java.lang.Object
  org.cojen.classfile.Descriptor
      org.cojen.classfile.MethodDesc

All Implemented Interfaces:

Serializable

public class MethodDesc
extends Descriptor
implements Serializable

This class is used to build method descriptor strings as defined in The Java Virtual Machine Specification, section 4.3.3. MethodDesc instances are canonicalized and therefore "==" comparable.
