Constructor Details

JavaScriptCompilerBase

protected JavaScriptCompilerBase(JasperReportsContext jasperReportsContext)

Creates a JavaScript compiler.

Method Details

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

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

loadEvaluator

protected JREvaluator loadEvaluator(Serializable compileData,
 String unitName)
                             throws JRException

Description copied from class: JRAbstractCompiler

Creates an expression evaluator instance from data saved when the report was compiled.

Specified by:

loadEvaluator in class JRAbstractCompiler

Parameters:

compileData - the data saved when the report was compiled

unitName - the evaluator unit name

Returns:

an expression evaluator instance

Throws:

JRException

defaultExpressionCreator

protected JavaScriptCompilerBase.ScriptExpressionVisitor defaultExpressionCreator()

oldExpressionCreator

protected JavaScriptCompilerBase.ScriptExpressionVisitor oldExpressionCreator()

estimatedExpressionCreator

protected JavaScriptCompilerBase.ScriptExpressionVisitor estimatedExpressionCreator()

getParameterVar

protected static String getParameterVar(String name)

getVariableVar

protected static String getVariableVar(String name)

getFieldVar
