Class CheckMethodAdapter

java.lang.Object
  org.objectweb.asm.MethodAdapter
      org.objectweb.asm.util.CheckMethodAdapter

All Implemented Interfaces:: MethodVisitor

public class CheckMethodAdapter
extends MethodAdapter

A MethodAdapter that checks that its methods are properly used. More precisely this code adapter checks each instruction individually (i.e., each visit method checks some preconditions based only on its arguments - such as the fact that the given opcode is correct for a given visit method), but does not check the sequence of instructions. For example, in a method whose signature is void m (), the invalid instruction IRETURN, or the invalid sequence IADD L2I will not be detected by this code adapter.
