Field Detail

generateClassFiles

protected boolean generateClassFiles

outputDir

protected java.lang.String outputDir

listGeneratedCode

protected boolean listGeneratedCode

primitiveTypes

protected static InjectionGenerator.PrimitiveTypeInfo[] primitiveTypes

instance

protected static InjectionGenerator instance

Constructor Detail

InjectionGenerator

public InjectionGenerator(boolean generateClassFiles,
                          java.lang.String outputDir,
                          boolean listGeneratedCode)

InjectionGenerator constructor

Parameters:

generateClassFiles - True if we should generate new class files containing injected methods. This is used by the batch injection code.

outputDir - If not the empty string, this is the directory in which generated class files should be stored.

listGeneratedCode - True if we should log the generated methods in the log file. This is only set when debugging InjectionGenerator.

Method Detail

getInstance

public static InjectionGenerator getInstance()

Get the InjectionGenerator singleton instance

maybeInjectMarshalling

public JavaClass maybeInjectMarshalling(JavaClass clazz,
                                        java.lang.Short typeNum)

This is the public method called by MarshallingRuntime to inject marshalling methods into the clazz argument

Parameters:

clazz - The BCEL JavaClass instance representing the class file

typeNum - The type number for the class

Returns:

The modified JavaClazz instance
