Class TypeDescriptor

java.lang.Object
  org.springsource.loaded.TypeDescriptor

All Implemented Interfaces:

org.objectweb.asm.Opcodes, Constants

public class TypeDescriptor
extends java.lang.Object
implements Constants

Encapsulates the information about a type relevant to reloading. The TypeDescriptor for a type is sometimes extracted whilst performing some other operation (eg. InterfaceExtractor) but can also be retrieved directly using TypeDescriptorExtractor.

Since:

0.5.0
