Method Detail

init

public void init(org.codehaus.jam.internal.elements.ElementContext ctx)

Description copied from class: JamClassBuilder

This method is called by JAM to initialize this class builder. Extending classes can override this to perform additional initialization work (just remember to call super.init()!).

Overrides:

init in class JamClassBuilder

build

public MClass build(java.lang.String pkg,
                    java.lang.String cname)

Description copied from class: JamClassBuilder

This is called by JAM when it attempts to load a class. If the builder has access to an artifact (typically a java source or classfile) that represents the given type, it should call createClassToBuild() to get a new instance of MClass and then return it. No caching should be performed - if an MClass is going to be returned, it should be a new instance returned by createClassToBuild()

If no artififact is available, the builder should just return null, signalling that other JamClassBuilders should attempt to build the class.
