Creates a new ClassDefinition binding using the supplied class and class file bytes. Does not copy the supplied buffer, just captures a reference to it.
Params:
  • theClass – the Class that needs redefining
  • theClassFile – the new class file bytes
Throws:
/** * Creates a new <code>ClassDefinition</code> binding using the supplied * class and class file bytes.
