Class RuntimeCallInitialiser

java.lang.Object

net.sandius.rembulan.runtime.RuntimeCallInitialiser

All Implemented Interfaces:

CallInitialiser

public class RuntimeCallInitialiser
extends Object
implements CallInitialiser

The default implementation of a call initialiser.

This class serves as a bridge between call executors defined in the package net.sandius.rembulan.exec and the runtime implementation.

Method Summary

Modifier and Type	Method and Description
static RuntimeCallInitialiser	forState(StateContext stateContext) Returns a new call initialiser for calls executed in the specified state context stateContext, and using the default return buffer factory (see ReturnBuffers.defaultFactory()).
static RuntimeCallInitialiser	forState(StateContext stateContext, ReturnBufferFactory returnBufferFactory) Returns a new call initialiser for calls executed in the specified state context stateContext that use return buffers initialised by the specified factory returnBufferFactory.
Continuation	newCall(Object fn, Object... args) Returns the Lua call fn(args...) reified as a continuation.
