public class Engine
extends Object
implements Serializable, NodeParser, ReportGenerator

This is the i-net Clear Reports report engine. Its purpose is to transform a report template and its associated data. The result can either be binary data to be viewed/printed by the viewer or it can be exported into a lot of export formats, like: HTML, PDF, PS, RTF, XLSX, XML, ....

The engine reads the report file and creates an array of output data that can be used by the client (java viewer or CSV, HTML, PDF, RTF, XLSX, XML, PS viewer, ...). The output data can be created by executing the following steps:

• Create a new engine by calling engine = new Engine(Engine.NO_EXPORT).
  To create a PDF render engine for example, use engine = new Engine(Engine.EXPORT_PDF).
• Set the path to the report template by calling engine.setReportFile("file:c:/report1.rpt") on windows or engine.setReportFile("/usr/share/clearreports/report1.rpt") on unix.
• Change the parameters of the report.
  For example if the report was created using ODBC to an Oracle database and you want to use a native driver (e.g. i-net SERO) instead to connect to a Oracle database, copy the file Sero.jar into the class path of i-net Clear Reports and set the name of the Data Source Configuration that should be used instead:
  

  
     DatabaseTables dbTables = engine.getDatabaseTables();
     Datasource ds = dbTables.getDatasource(0);
     ds.setDataSourceConfigurationName("Oracle_DataSourceConfiguration");
    

  Also, you could change the selection formula and examine or change other parts of the report template using RDC if you wish.
• Execute the report.
  Executing a report means transforming the report template together with the data from the database (or with the data that you have set using the method engine.setData()) into the target format (PDF, RTF, HTML, binary, ...).
• The last action would be to call the method engine.getPageData(int) which returns the requested report page.
• A report which has been executed can not be used further, you can not use neither engine.setReportFile() nor all other set or get methods other then the getPage*() methods on an executed report.

Note that the above command sequence will usually be located in a callback, for example in the checkProperties(Engine e, Properties p) callback of the ReportServlet or the ReportSocket. The callback will always be invoked when the viewer requests data from you.
In general you do not have to use the methods of this class directly. If you use the ReportServlet or the ReportSocket (Report Server), then you use a report URL instead which the ReportServlet and the ReportSocket parses and automatically calls the necessary setter methods for you. For example if you specify the URL http://localhost:9000/?report=file:c:/report1.rpt&datasource=Oracle_DataSourceConfiguration then the ReportSocket will automatically invoke the above code sequence.

However, you can use one of the checkProperties() callbacks to change the parameters before the above set methods are called (for example if you want to set or change the password).

If you want to use RDC, you can use the checkProperties(Engine e, Properties p) callback to examine and change the fields of the engine before the engine will execute the report.

setLocale

public void setLocale(@Nonnull
 Locale locale)
               throws ReportException

Sets the locale, which will be used for language independent reports. This locale will be used for formating of field values (number, date, time boolean, ... ) and for the translation of labels used in reports into the language specified in the locale. It will be not used for formatting of the result of formula functions like CDbl, ToText etc. The locale is either the one used by the operating system of the client or the one specified in the report URL as property "locale". The strings for the different languages are saved in ResourceBundles. The base class for the ResourceBundles need to be specified in the i-net Clear Reports configuration using the Configuration Manager.
This method also sets the locale for the sub-reports of the engine. If you want to set a different locale for one of the sub-reports then please set the language for the sub-report engine after you've set the language for the main report engine.

Parameters:

locale - The locale to be used by the client

Throws:

ReportException - if Engine is not initialized or finished.

setUserProperties

public void setUserProperties(Properties props)
                       throws ReportException

With this method you can associate additional data with the engine of the main report. Later you can use this data e.g. in your own class that is derived from Database.
The data are always attached to the main report engine, never to the sub report engine(s).
To set data for main or subreport engine use the method setUserData(Hashtable). A list and description of interpreted properties can you find in the Report URL Parameters.

Specified by:

setUserProperties in interface ReportGenerator

Parameters:

props - The data to be set in a Properties object.

Throws:

ReportException - if Engine is not initialized or finished.

getUserProperties

public Properties getUserProperties()

Returns the user data that has been set either with setUserProperties(), checkProperties() or in the report URL.
This method can be useful if you have additional properties which should be associated with the engine. But please see also the method set/getUserData(Hashtable data) which is probably more useful.

Returns:

The user properties or null if user properties not set.

Since:

6.0

See Also:

• setUserProperties(Properties props)
• setUserData(Hashtable data)
• getUserData()

getUserData

public Hashtable<Object,Object> getUserData()

Returns the user data that has been set with setUserData(Hashtable).
This method can be useful e.g. in your own database class, a class that extends from com.inet.report.Database and in that you set the report data without a JDBC connection e.g. with an external ResultSet.
For instance you can use this method to get the selection formula (sf) specified in the report URL and use it to fill you own ResultSet in your database class:

   public void getReportData( Engine engine, String configs ) {
       try {
           ...
           // get the url properties from the report URL
           Hashtable p = engine.getUserData();
           String[] cols = p.get("my_cols"));
           ...
           engine.setData(cols, data, true);
       } catch (Throwable t) {Utils.printStackTrace(t);}
    }

In the report URL you can set these parameter, e.g.:
http://<servername>:9000/?report=...rpt&...&sf=table.field=5

Returns:

The user data associated with this report.

Since:

6.0

See Also:

• setUserData(Hashtable)
• setUserProperties(Properties props)
• getUserProperties()

setUserData

public void setUserData(Hashtable<Object,Object> hash)

With this method you can associate additional data with the engine and retrieve it later (e.g. in a class that is derived from Database). The data are always attached to the current engine.

Parameters:

hash - The data to be set.

getParent

public Engine getParent()
                 throws ReportException

Returns the parent Engine for the current subreport or null if the current engine is the engine for the main report.

Returns:

The parent engine or null.

Throws:

ReportException - if Engine is finished.

Since:

6.0

execute

public void execute()
             throws ReportException

Executes the report and stores the result data in an internal cache. Before you can execute the report generation you need to set all options. You need to call this method before you can request the page data with getPageData.

Specified by:

execute in interface ReportGenerator

Throws:

ReportException - if Engine is not initialized or finished.

Since:

6.0

See Also:

• getPageData(int)

getPageData

public byte[] getPageData(int page)
                   throws ReportException

Returns the data of a single report page. If no export format has been specified for this engine then this method returns the binary data of one report page. These binary data are useful for the Java client only.
If an export format has been specified (e.g. EXPORT_PDF) for this engine [new Engine(Export_Format)] then this method returns the bytes of a report page or of a part (e.g. XLS sheet) of the report. For the export to PDF, RTF, XLS, XML and CSV it is necessary to write the bytes of all pages to a single file to get a valid export file (e.g. .pdf).
If the export to PS is used then it is possible to use the single pages of the .ps file, e.g. for printing.
The html export creates one html file for each report page and one jpg file for each image in the report. Therefore it is necessary to create multiple files from the byte array returned from getPageData (see samples/export/ExportWithoutViewerToHTML.java).

With the following code you can export into a .pdf file:

 Engine engine = new Engine(Engine.EXPORT_PDF);
 engine.setReportFile( "file:D:/reports/MySample.rpt" );
 engine.execute();
 File pdfFile = new File("D:/exports/sample.pdf");
 FileOutputStream fos = new FileOutputStream(pdfFile);
 for(int i=1;i<=engine.getPageCount();i++){
     fos.write(engine.getPageData(i));
 }
 fos.close();
 

Please note: Before you can call this method you need to call engine.execute() to execute and render the report.
This method is waiting until the rendering process of the requested page has been finished.

Specified by:

getPageData in interface ReportGenerator

Parameters:

page - The number of the page. The first page is 1, the second is 2, ... . If the page number is bigger than the page count then null will be returned.

Returns:

the binary data for the Java Viewer or the bytes of the exported file (page).

Throws:

IllegalArgumentException - if the page number is zero or negative.

ReportException - If rendering the page encounters a problem

Since:

6.0

See Also:

If fontID is greater than the number of embedded fonts available it will return the last font available.

Parameters:

fontID - Identifying number of font to fetch

Returns:

the encoded byte array of the embedded font at the specified fontId or null if not font is available.

Throws:

IllegalArgumentException - If fontID is less than 1.

setCatalog

public void setCatalog(String catalog)
                throws ReportException

Sets the database name that will be used at runtime instead of the database name that was specified at design time in the report template. If the used database does not support catalogs (e.g. ORACLE databases) then these parameter will be ignored.
This parameter has an effect only if a catalog was specified at design time. It is not possible to change the catalog if it was not specified at design time.
This function is a convenience function that sets the catalog for the main and all sub reports. Please see the appopriate function in DatabaseTables which only modifies the parameters of the current report.

This method only points to the first datasource of the report and sub reports.

Parameters:

catalog - name of the catalog

Throws:

ReportException - if Engine is not initialized or finished.

Since:

6.0

setData

public void setData(String[] columns,
 Object[][] data,
 boolean longColumnNames)
             throws ReportException

Sets the report data with external data without the use of a JDBC driver. You only need this function if you do not use a JDBC driver. You can create a rpt template with the report designer or RDC on dummy tables. At runtime you do not have database access.
If a record or group selection formula is set, it will still be evaluated after reading the ResultSet. If you do not wish this, you should remove these formulas with setSF(String) and/or setGF(String).
Note that this does not work with a "query file"; fetching data via a query file takes always precedence even if you call setData().
Example:

Engine eng = new Engine( Engine.NO_EXPORT );
eng.setReportFile( "file:C:/report/MySample.rpt" );
String[] columns = {"TestTable.ID", "TestTable.Name"};
Object[][] data =
{{new Integer(10), "John"},
{new Integer(20), "Peter"},
{new Integer(23), "Ana"}};
eng.setData( columns, data, true );
eng.execute();

Make sure you do not not modify the arrays, columns and data. The Engine does not create a copy of it. The Engine modifies the data array on execute(). Do not use the same array for two calls of setData(). You need to create a copy (for example with clone() ).
As column names it is recommended to set them full qualified: <tableName>. <columnName>

Parameters:

columns - The names of the columns in the report template. This names are case in-sensitiv.

data - the report data. Supported datatypes are: all instances of Number, String and byte[].

longColumnNames - this flag is obsolete since i-net Crystal-Clear 5.3

Throws:

setData

public void setData(List<String> columns,
 List<?> data,
 boolean longColumnNames)
             throws ReportException

The columns contains the strings with the columns names. The data can contain object arrays or vectors with the data for the columns. It is a wrapper for the methods with arrays.
If a record or group selection formula is set, it will still be evaluated after reading the ResultSet. If you do not wish this, you should remove these formulas with setSF(String) and/or setGF(String).

Parameters:

columns - must include Strings only

data - can include Vectors or Object[]

longColumnNames - this flag is obsolete since i-net Crystal-Clear 5.3

Throws:

ReportException - If there are problems with the engine not being initialized or with the data not being valid

If a record or group selection formula is set, it will still be evaluated after reading the ResultSet. If you do not wish this, you should remove these formulas with setSF(String) and/or setGF(String). Note that this does not work when using a "query file"; fetching data via a query file takes always precedence even if you call setData().

Object[][] data =
{{new Integer(10), "John"},
{new Integer(20), "Peter"},
{new Integer(23), "Ana"}};
eng.setData( columns, data );
eng.execute();

Make sure you do not not modify the arrays, columns and data. The Engine does not create a copy of it. The Engine modifies the data array on execute(). Do not use the same array for two calls of setData(). You need to create a copy (for example with clone() ).

setConnection

public void setConnection(Connection con)
                   throws ReportException

Sets the connection object to the engine of the main- or subreport.
You can use this method for instance if you have your own pool of database connections so that you can take the advantage of your own pooled connections.
The i-net Clear Reports engine will close the connection after using it, thus indicating to the pool manager that the connection is no longer in use. The pool manager can then re-use the real connection.
The main report and each subreport need it's own connection so you need to set separate connections for the main and the subreport(s).

Please note:
1. This method set the catalog to Null. Therefore it is only possible to execute a main or subreport to one database (catalog).
2. The method setConnection() replace the database connection, only. It does not change the settings of the Data Source Configuration on that the report was designed. The driver for a given Data Source Configuration need to be configured as if setConnection() were not used.
3. The properties (like "supports SQL92", "supports brackets in join", "alias keyword", ...) on the Data Source Manager tab "Compatibility Settings" can be used to configure the set connections.

You can find more information about the Data Source Manager in the documentation (click here to read it online).

Code Example:

Class.forName("com.inet.ora.OraDriver");
Engine eng = new Engine( Engine.NO_EXPORT );
eng.setReportFile( "file:C:/report/MySample.rpt" );
Connection con = DriverManager.getConnection("jdbc:inetora:host:port:sid?user=USRName&password=PWD");

setData

public void setData(ResultSet resultSet)
             throws NullPointerException,
SQLException,
ReportException

Sets the report data with an ResultSet. You can create a report file with the report designer on dummy tables (i.e. create a report file that accesses a database). At runtime you can set different ResultSet's for the same report template.
If a record or group selection formula is set, it will still be evaluated after reading the ResultSet. If you do not wish this, you should remove these formulas with setSF(String) and/or setGF(String).
Note: This does not work when using a "query file";
To fetching data via a query file takes always precedence even if you call setData().

If it is not executable on the database then i-net Clear Reports will execute it after the data was fetched from the database.
The result of the selection formula need to be a boolean, that means 'true' or 'false'.
If you want to use a database field in the new selection formula that was not added to your report at design time or that was not used in the old selection formula, then you have to add it into your report design.
The record selection formula need to be in Crystal Syntax for formulas.
For example: engine.setSF("if ({table.row} = 1) then true else false");
The expression is evaluated either on the database server when the expression could be translated into a where ... clause or by the report engine when fetching records. The formula must return true or false.

Parameters:

sf - record selection formula to use, null if record selection is to be removed.

Throws:

ReportException - if Engine is not initialized or finished.

setPrompt

public void setPrompt(String value,
 int i)
               throws ReportException

Specifies the value for a parameter field in the report. Parameter field values are assigned to parameter fields in that order the parameter field exists in the report.

For example: engine.setPrompt("Date(2001,01,01)", 0);
To set the value for a parameter field with multiple values use the array syntax, e.g.:
engine.setPrompt("[Date(2001,01,01),Date(2007,05,15)]", 0);
To set a string value with quotation marks at the beginning and at the end which should be displayed in the report, you need to add additional quotation marks, e.g.:
engine.setPrompt("MyStringPrompt","\"\"string-value\"\"");.

Note: The expression will be executed before any data will be fetched from the database.

Specified by:

setPrompt in interface ReportGenerator

Parameters:

value - value for parameter field i

i - index in the parameter list

If the name is not in the parameter list the call is ignored.

For example: engine.setPrompt("MyDatePrompt","Date(2006,01,03)");
To set the value for a parameter field with multiple values use the array syntax, e.g.:
engine.setPrompt("MyDatePrompt","[Date(2001,01,01),Date(2007,05,15)]");.
To set a value with quotation marks at the beginning and at the end which should be displayed in the report, you need to add additional quotation marks, e.g.:
engine.setPrompt("MyStringPrompt","\"\"string-value\"\"");.

Note: The expression will be executed before any data will be fetched from the database.

Note also that if you want to set the value of a prompt in a subreport, you should use the following syntax: #SubreportID#Name
For example: #2#TestName would address a prompt called "TestName" in the second subreport.

public void setPrompts(Vector<?> prompts)
                throws ReportException

Deprecated.

As of i-net Clear Reports 19.0, use setPrompt(PromptField, String), setPrompt(String, int) or setPrompt(String, String)

Specifies value for parameter fields in the report. Only String values are accepted in the Vector. If you want set Object values then you need to do this with getFields().getPromptField(x).setPromptValue(value). Parameter field values are assigned to parameter fields in that order the parameter field exists in the report.
Make sure that parameter field values appear in the Vector in the same order the parameter fields appears in the report.

For example:
Vector prompts = new Vector();
prompts.add("Date(2006,01,03)");
...
engine.setPrompt(prompts);

Note: The expression will be executed before any data will be fetched from the database.

Parameters:

prompts - Vector containing parameter field values as String objects, e.g.: "Date(2005,31,12)"

setSql

public void setSql(String statement)
            throws ReportException

Replaces all defined tables and joins by this SQL statement. If a record or group selection formula is set, it will still be evaluated after reading the ResultSet. If you do not wish this, you should remove these formulas with setSF(String) and/or setGF(String). This will cause a query to the database for the meta data of the supplied SQL statement. If not all required columns have been specified in the supplied SQL statement this will throw a ReportException with error code 1212.
Note: This can cause a loss of performance or fail for complex SQL statements. If you experience any problem with this method you should use setSqlIgnoreMetaData(String) instead which will not query the meta data for the SQL statement. Please also note that in this case no ReportException will be thrown if the SQL statement does not contain all required columns for the report. The error will occur at execution then. (error code 14)

Parameters:

statement - The SQL statement

Throws:

ReportException - If not all required columns have been specified in the supplied SQL statement (error code 1212) or an error occurred during setting the SQL statement.

Since:

6.0

setSqlIgnoreMetaData

public void setSqlIgnoreMetaData(String statement)
                          throws ReportException

Replaces all defined tables and joins of this report with the supplied sql statement. In contrast to setSql(String) this call will not check the supplied sql statement to return all required columns for the report. This means that no request for meta data information will be sent to the database.
If a record or group selection formula is set, it will still be evaluated after reading the ResultSet. If you do not wish this, you should remove these formulas with setSF(String) and/or setGF(String).
Note: As this will not check if all required columns have been specified in the supplied sql statement it is not guaranteed that the report will work with the sql statement. If not all required columns have been specified this will cause a ReportExeption with error code 14 after the engine has been executed with execute(). You can check if an error occurred during rendering by calling getErrorMsg() after execution.

Parameters:

statement - The sql statement which should be executed for this report.

Throws:

ReportException - If an error occurred during setting the sql statement.

setSql

public void setSql(String statement,
 boolean useColumnIndexFromReportDesign)
            throws ReportException

Manually sets the SQL statement that will be send to the database to fetch the report data. If you set a sql statement then this statement will work like a stored procedure that means that the long names "table.column" are not available but only the short name "column".
Instead of using setSql directly, it often can make more sense to call engine.setSF() which overrides the record selection formula ("where ...").
If you want to use long column names (for example table1.field1), then you should set useColumnIndexFromReportDesign to true. This method is meant for advanced users who wish to manually enter their own SQL statment. Note that this is only possible if the report design contains the column names specified in your statement. Furthermore you must create a select statement that matches the column index in the report design (for example you could use the original select statement from the report designer and then modify the where and order by clause only).

Parameters:

statement - The SQL statement

useColumnIndexFromReportDesign - is obsolete.

Throws:

ReportException - if Engine is not initialized or finished.

getDefaultSqlOfAllStatements

public String[] getDefaultSqlOfAllStatements(boolean leavePrompts)
                                      throws ReportException

Returns the statements that will be send to the database.
The result depends on the used DataFactories classes. Non JDBC DataFactories produce an empty string. NOTE: If there are prompt fields in the record selection formula and the prompts are not yet set and 'leavePrompts' is set to false, the prompt fields will be replaced by #CONSTANT ...# placeholders to indicate, that some parts of the statement will be constant at runtime but don't have a final value yet.

Parameters:

leavePrompts - If true, PromptFields used in the statement will be replaced by its placeholder.

Returns:

The statements that will be send to the database.

Throws:

ReportException - If creating the statements failed or the engine is finished.

getMetaProperties

public Properties getMetaProperties()

Returns any meta properties belonging to this engine. This is NOT a copy but the actual Properties itself - adding or removing properties to this Properties object will add or remove them for this engine. Note that these properties will have NO effect on the rendering of a report. Note also that properties with the prefix "designer" are reserved for use by i-net Designer and should therefore not be used or manipulated. Properties should be string pairs of keys and values: non-string values will lead to issues when saving. See the documentation for Properties

Returns:

purely design-time meta properties of this engine. never null.

Since:

10.0

setMetaProperties

public void setMetaProperties(Properties props)

Sets (and overwrites!) the meta properties which will be stored in the report file if the engine is saved and retrieved if this report file is loaded. Note that these properties will have NO effect on the rendering of a report. Note also that properties with the prefix "designer" are reserved for use by i-net Designer and should therefore not be used or manipulated. Finally, note that any existing meta properties will be overwritten by this method. If you only want to add properties to the report, use getMetaProperties() instead and add your properties to the Properties object.

Parameters:

props - Properties to set. May not be null.

Throws:

IllegalArgumentException - if props is null
