Method Detail

name

protected abstract String name()

Returns the name of the function for error-reporting.

Returns:

the function name

invoke

public void invoke(org.classdump.luna.runtime.ExecutionContext context,
                   Object[] args)
            throws org.classdump.luna.runtime.ResolvedControlThrowable

Specified by:

invoke in class org.classdump.luna.runtime.LuaFunction<Object,Object,Object,Object,Object>

Throws:

org.classdump.luna.runtime.ResolvedControlThrowable

invoke

protected abstract void invoke(org.classdump.luna.runtime.ExecutionContext context,
                               ArgumentIterator args)
                        throws org.classdump.luna.runtime.ResolvedControlThrowable

Invokes the function in the context context with arguments passed in the iterator args.

This is the method that is meant to be implemented by the function implementation. The function should not retain a reference to context or args beyond the scope of its invocation. In particular, context and args should not be part of suspended state if this method throws a control throwable.

context and args are guaranteed to be non-null when the function is invoked via Dispatch.

Parameters:

context - execution context, must not be null

args - call arguments, must not be null

Throws:

org.classdump.luna.runtime.ResolvedControlThrowable - if the call initiates a non-local control change

resume

public void resume(org.classdump.luna.runtime.ExecutionContext context,
                   Object suspendedState)
            throws org.classdump.luna.runtime.ResolvedControlThrowable

Throws:

org.classdump.luna.runtime.ResolvedControlThrowable
