Class Method

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.

compile_push_this

public void compile_push_this()

compile_push_value

public void compile_push_value(Variable var)

Deprecated:

compile_store_value

public void compile_store_value(Variable var)

Deprecated:

getAttributes

public final Attribute getAttributes()

getCode
