handlesClass

public final boolean handlesClass(ClassProcessor.SelectionContext context)

Description copied from interface: ClassProcessor

Returns whether the processor wants to recieve the class.

Parameters:

context - the context of the class to consider

Returns:

whether the processor wants to recieve the class

processClass

public final ClassProcessor.ComputeFlags processClass(ClassProcessor.TransformationContext context)

Description copied from interface: ClassProcessor
