Class Method

java.lang.Object
gnu.bytecode.Method
All Implemented Interfaces:
AttrContainer, Member
public class Method extends Object implements AttrContainer, Member
Represents a method in a ClassType.

A Method contain a CodeAttr object; the interface for generating bytecode instructions is primarily in CodeAttr.

All the methods whose name start with compile_ are deprecated, and should not be used; use the methods in CodeAttrinstead.

  • Constructor Details

    • Method

      public Method(Method base, ClassType clas)
      A copy constructor, except you can override the declaring class. This can be used to improve binary compatibility by emitting method references where the declared class is the type of the receiver.
