All Implemented Interfaces:

Callable

public class Apply
extends Site

Apply a callable to a list of arguments. HACK: this is a subclass of site but has slightly different semantics: the callable argument is forced as a call (i.e. free variables in the callable are not forced).

createCall

public void createCall(Token caller,
                       java.util.List<java.lang.Object> args,
                       Node nextNode)
                throws TokenException

Description copied from class: Site

Invoked by a Call to invoke a site. The argument list is scanned to make sure that all parameters are bound. If an unbound parameter is found, the call is placed on a queue and nothing more is done. Once all parameters are bound, their values are collected and the corresponding subclass (the actual site) is called.

Specified by:

createCall in interface Callable

Overrides:

createCall in class Site

Parameters:

caller - token for which the call is being made: points to the call node

args - argument list

nextNode - next node after the call node, to which the result should be sent

Throws:

TokenException

callSite

public void callSite(Args args,
                     Token caller)
              throws TokenException

Description copied from class: Site

Must be implemented by subclasses to implement the site behavior

Specified by:

callSite in class Site

Parameters:

args - list of argument values

caller - where the result should be sent

Throws:

TokenException
