## README

async-task-mgr
==============

## Intro
A simple nodeJS module for async task manager. Identical tasks will be executed only once and the result will be saved for further use.

## Features

* tasks with the same name are identified as **the same**, and will be executed only once
* task result will be saved for further use


## How to use

``npm install async-task-mgr --save``

## Sample
```javascript
var asyncTask = require("async-task-mgr");

var asyncTaskInstance = new asyncTask();

function taskAction(callback){
	setTimeout(function(){ //simulate an async task
		var resultA = Math.floor(Math.random()*100),
			resultB = Math.floor(Math.random()*100),
			resultC = Math.floor(Math.random()*100);

		callback(resultA, resultB, resultC);
	},2000); 
}

//add a new task named task_A
//when taskAction is done, its return value will be saved and apply to all the task with the same name
asyncTaskInstance.addTask("task_A",taskAction,function(resultA,resultB,resultC){ 
	console.log("task A_1 result :" + resultA + " " + resultB + " " + resultC); //all result generated by taskAction will be passed here
});


//add a new task named task_A
/*
since a task with the same name has been added, this taskAction will not be executed.
the callback function will be put in a queue and will be called when previous callbacks are done.
*/
asyncTaskInstance.addTask("task_A",taskAction,function(resultA,resultB,resultC){
	console.log("task A_2 result :" + resultA + " " + resultB + " " + resultC);
});


//add a new task named task_X
//a new task, have no relationship to the previous ones
asyncTaskInstance.addTask("task_X",taskAction,function(resultA,resultB,resultC){
	console.log("task X_0 result :" + resultA + " " + resultB + " " + resultC);
});

```
