Class 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 Detail

      • 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.
