Class CheckClassAdapter

Implemented Interfaces:
ClassVisitor
public class CheckClassAdapter
extends ClassAdapter
A ClassAdapter that checks that its methods are properly used. More precisely this class adapter checks each method call individually, based only on its arguments, but does not check the sequence of method calls. For example, the invalid sequence visitField(ACC_PUBLIC, "i", "I", null) visitField(ACC_PUBLIC, "i", "D", null) will not be detected by this class adapter.
