Class FunctionCompiler

java.lang.Object

net.oneandone.mork.compiler.CustomCompiler

net.oneandone.mork.compiler.FunctionCompiler

All Implemented Interfaces:

Bytecodes

public class FunctionCompiler
extends CustomCompiler
implements Bytecodes

Generates classes derived from CompiledFunctionBase classes. Generates zero, one (or multiple if the code attribute grows to big) instances of InvocationCode that perform the actual work. Support multiple instances of InvocationCode is currently rarely used because it takes quite a few functions to exceed InvocationCode's code attribute size. However, future versions might generate more code into InvocationCode.
