Synopsis

This class is a simple wrapper around a Class object and an array of bytes that represents a class file for that class. An array of ClassDefinition objects is passed to the redefineClasses( ) method of the Instrumentation class. Class redefinitions are allowed to change method implementations, but not the members or inheritance of a class or the signature of the methods.
