Method Detail

compileUnits

protected String compileUnits(JRCompilationUnit[] units,
                  String classpath,
                  File tempDirFile)

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 class JRAbstractCompiler

Parameters:

units - the compilation units

classpath - the compilation classpath

tempDirFile - temporary directory

Returns:

a string containing compilation errors, or null if the compilation was successfull

getNameEnvironment

protected org.eclipse.jdt.internal.compiler.env.INameEnvironment getNameEnvironment(JRCompilationUnit[] units)

getCompilerRequestor

protected JRJdtCompiler.CompilerRequestor getCompilerRequestor(JRCompilationUnit[] units)

getJdtSettings

protected Map<String,String> getJdtSettings()

getResource

protected InputStream getResource(String resourceName)

loadClass

protected Class<?> loadClass(String className)
                      throws ClassNotFoundException

Throws:

ClassNotFoundException

checkLanguage

protected void checkLanguage(String language)
                      throws JRException

Description copied from class: JRAbstractCompiler

Checks that the report language is supported by the compiler.

Specified by:

checkLanguage in class JRAbstractCompiler

Parameters:

language - the report language

Throws:

JRException

recreateCompileUnit

protected JRCompilationUnit recreateCompileUnit(JRCompilationUnit compilationUnit,
                                    Set<Method> missingMethods)

generateSourceCode

protected JRCompilationSourceCode generateSourceCode(JRSourceCompileTask sourceTask)
                                              throws JRException

Description copied from class: JRAbstractCompiler

Generates expression evaluator code.

Specified by:

generateSourceCode in class JRAbstractCompiler

Parameters:

sourceTask - the source code generation information

Returns:

generated expression evaluator code

Throws:

JRException

getSourceFileName

protected String getSourceFileName(String unitName)

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 class JRAbstractCompiler

Parameters:

unitName - the unit name

Returns:

the source file name

getCompilerClass

protected String getCompilerClass()

Overrides:

getCompilerClass in class JRAbstractCompiler
