Class WrapperClassGenerator

java.lang.Object

jmplib.util.WrapperClassGenerator

public class WrapperClassGenerator
extends java.lang.Object

Helper class to generate source code of wrapper classes. This class encapsulates dynamic code into classes to compile them and invoke the dynamic code.

Version:

1.1 (Redondo) Adds the possibility of generating eval code that uses imports to simplify dynamic cod. Adds the final modifier to generated eval methods to improve performance. Adds a map of simple type names to their Class object to improve performance.
