comb.PromiseList Public

PromiseList object used for handling a list of Promises

Example 
  1. var myFunc = function(){
  2.     var promise = new Promise();
  3.     //callback the promise after 10 Secs
  4.     setTimeout(hitch(promise, "callback"), 10000);
  5.     return promise.promise();
  6. }
  7. var myFunc2 = function(){
  8.     var promises =[];
  9.     for(var i = 0; i < 10; i++){
  10.         promises.push(myFunc);
  11.     }
  12.     //create a new promise list with all 10 promises
  13.     return new PromiseList(promises).promise();
  14. }
  15.  
  16. myFunc.then(function(success){}, function(error){})
  17. //chain promise operations
  18. myFunc.chain(myfunc).then(function(success){}, function(error){})
  19.  
  20. myFunc2.then(function(success){}, function(error){})
  21. //chain promise operations
  22. myFunc2.chain(myfunc).then(function(success){}, function(error){})
  23.
