compileUnits
protected String compileUnits(JRCompilationUnit[] units, String classpath, File tempDirFile) throws JRException Description copied from class:JRAbstractCompiler
Compiles several expression evaluator units.The result of the compilation should be set by calling
setCompileData
on all compile units.- Specified by:
compileUnits
in classJRAbstractCompiler
- Parameters:
units
- the compilation unitsclasspath
- the compilation classpathtempDirFile
- temporary directory- Returns:
- a string containing compilation errors, or null if the compilation was successfull
- Throws:
JRException
-
checkLanguage
Description copied from class:JRAbstractCompiler
Checks that the report language is supported by the compiler.- Specified by:
checkLanguage
in classJRAbstractCompiler
- Parameters:
language
- the report language- Throws:
JRException
-
generateSourceCode
protected JRCompilationSourceCode generateSourceCode(JRSourceCompileTask sourceTask) throws JRException Description copied from class:JRAbstractCompiler
Generates expression evaluator code.- Specified by:
generateSourceCode
in classJRAbstractCompiler
- Parameters:
sourceTask
- the source code generation information- Returns:
- generated expression evaluator code
- Throws:
JRException
-
getSourceFileName
Description copied from class:JRAbstractCompiler
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
COMPILER_KEEP_JAVA_FILE
is set, the generated source will be saved in a file having the name returned by this method.- Specified by:
getSourceFileName
in classJRAbstractCompiler
- Parameters:
unitName
- the unit name- Returns:
- the source file name
