arieh/functionstack

A mootols class that allows stacking functions and calling them step by step or periodicaly.

FunctionStack

A very simple class that allows stacking functions and calling them step by step or priodiacly. This class is different from Chain in few ways:

1. It is ment to be used as a periodical caller - the play method.
2. It is posible to pass arguments to the functions in the stack.
3. It is ment to be used as a standalone, not to be implemented by other classes. Class method names are trivial and probably will be needed by implementors (push, play, clear, reset, stop, pause).

How to use

This is quite stright farward:

#JS
var stack = new FunctionStack(
	function(){console.log('a');},
	function(){console.log('b');},
	function(){console.log('c');},
	function(){console.log('d');},
	function(){console.log('e');}
);

stack.step(); //will call log 'a'

stack.play(); //will log 'b' 'c' 'd' 'e' periodicaly (defualt to 1000 miliseconds)

Methods

1. push (function[,function[,...]]): Recives an unlimited list of functions. Adds them to the stack.
2. step : Will call the next function in the stack. If any paramaters were sent, will send them to the function.
3. play (int duration, array args) : Will step through the stack priodicaly. If args is supplied, will pass them to the functions.
4. pause : Will pause the periodical call.
5. stop : Will stop the periodcal call, reseting the counter.
6. reset : will reset the stack index.
7. clear : will clear the stack.
