| Method Summary | |
| abstract protected void | checkLanguage(String language)
Checks that the report language is supported by the compiler. | | final public JasperReport | compileReport(JasperDesign jasperDesign)
| | abstract protected String | compileUnits(JRCompilationUnit[] units, String classpath, File tempDirFile)
Compiles several expression evaluator units. | | abstract protected JRCompilationSourceCode | generateSourceCode(JRSourceCompileTask sourceTask)
Generates expression evaluator code. | | protected String | getCompilerClass()
| | abstract protected String | getSourceFileName(String unitName)
Returns the name of the source file where generated source code for an unit is saved. | | public static String | getUnitName(JasperReport report, JRDataset dataset)
Returns the name of the expression evaluator unit for a dataset of a report. | | protected static String | getUnitName(JRReport report, JRDataset dataset, String nameSuffix)
| | public static String | getUnitName(JasperReport report, JRCrosstab crosstab)
Returns the name of the expression evaluator unit for a crosstab of a report. | | protected static String | getUnitName(JRReport report, JRCrosstab crosstab, JRExpressionCollector expressionCollector, String nameSuffix)
| | protected static String | getUnitName(JRReport report, int crosstabId, String nameSuffix)
| | public JREvaluator | loadEvaluator(JasperReport jasperReport)
| | public JREvaluator | loadEvaluator(JasperReport jasperReport, JRDataset dataset)
| | public JREvaluator | loadEvaluator(JasperReport jasperReport, JRCrosstab crosstab)
| | abstract protected JREvaluator | loadEvaluator(Serializable compileData, String unitName)
Creates an expression evaluator instance from data saved when the report was compiled. |
| JRAbstractCompiler | | protected JRAbstractCompiler(boolean needsSourceFiles)(Code) | | Constructor.
Parameters:
needsSourceFiles - whether the compiler needs source files or is able to do in memory compilationIf true, the generated code is saved in source files to be used by the compiler. |
| checkLanguage | | abstract protected void checkLanguage(String language) throws JRException(Code) | | Checks that the report language is supported by the compiler.
Parameters:
language - the report language
throws:
JRException - |
| compileUnits | | abstract protected String compileUnits(JRCompilationUnit[] units, String classpath, File tempDirFile) throws JRException(Code) | | Compiles several expression evaluator units.
The result of the compilation should be set by calling
JRCompilationUnit.setCompileData(Serializable) setCompileData on all compile units.
Parameters:
units - the compilation units
Parameters:
classpath - the compilation classpath
Parameters:
tempDirFile - temporary directory a string containing compilation errors, or null if the compilation was successfull
throws:
JRException - |
| getSourceFileName | | abstract protected String getSourceFileName(String unitName)(Code) | | Returns the name of the source file where generated source code for an unit is saved.
If the compiler needs source files for compilation
or
JRProperties.COMPILER_KEEP_JAVA_FILE COMPILER_KEEP_JAVA_FILE is set, the generated source
will be saved in a file having the name returned by this method.
Parameters:
unitName - the unit name the source file name |
| getUnitName | | public static String getUnitName(JasperReport report, JRDataset dataset)(Code) | | Returns the name of the expression evaluator unit for a dataset of a report.
Parameters:
report - the report
Parameters:
dataset - the dataset the generated expression evaluator unit name |
| getUnitName | | public static String getUnitName(JasperReport report, JRCrosstab crosstab)(Code) | | Returns the name of the expression evaluator unit for a crosstab of a report.
Parameters:
report - the report
Parameters:
crosstab - the crosstab the generated expression evaluator unit name |
| loadEvaluator | | abstract protected JREvaluator loadEvaluator(Serializable compileData, String unitName) throws JRException(Code) | | Creates an expression evaluator instance from data saved when the report was compiled.
Parameters:
compileData - the data saved when the report was compiled
Parameters:
unitName - the evaluator unit name an expression evaluator instance
throws:
JRException - |
