net.oneandone.mork.compiler.InvocationCode

All Implemented Interfaces:

Bytecodes

public class InvocationCode
extends Object
implements Bytecodes

Generates bytecode for invoke methods. Must not be saved without functions. Java bytecode does not offer pointers to code. For that reason, there are three ways for functions to refer to the code to be executed when invoking the function (1) store a string and use reflection to refer to some generated method (2) generate a new class for every functions and store a pointer to an instance (3) use invocationCode Solution (1) is to slow. Solution (2) generates to many classes.
