Re: [royale-asjs] branch develop updated: Added taskToPromise and promiseToTask
Posted by Harbs <ha...@gmail.com>.
FYI:
This commit adds easy conversion between the Promise paradigm and the Task paradigm.
I’ve taken to coding using AsyncTasks for pretty much all my async code. It has greatly improved code readability. But sometimes it’s necessary to convert between tasks and promises — especially when dealing with third party libraries.
taskToPromise and promiseToTask fill that need.
taskToPromise(someTask).then(function(result){
// do something with a promise result
});
or if you need to return a promise and are using tasks:
return taskToPromise(someTask)
For the reverse when you get a promise from some code and want to use it with tasks (i.e. CompoundAsyncTask or similar):
var task:PromiseTask = promiseToTask(promise);
HTH,
Harbs
