## What I want
|
|
|
|
```d
|
|
// Create en event engine (it logs promises)
|
|
Eventy eventy = new Eventy();
|
|
|
|
/**
|
|
* Create a new promise who's job is to run the
|
|
* provided lambda `(x) => (x*2)`
|
|
*/
|
|
Promise myPromise = eventy.new((x) => (x*2));
|
|
|
|
/**
|
|
* Chain a promise to this one such that upon completion of
|
|
* `myPromise` then `promise2` will run and `myPromise` will only
|
|
* be considered completely done once everything from its chain forward is
|
|
*
|
|
* NOTE: That a promise is only completed then once its chain forwards
|
|
* is completed
|
|
*/
|
|
Promise promise2 = eventy.new((x)=>());
|
|
myPromise.then(promise2);
|
|
|
|
/**
|
|
* Now start the promise and await its completion,
|
|
* this will basically sleep the calling thread
|
|
* till it awakes. It returns a result
|
|
*
|
|
* Internally this calls `this.execute()` and
|
|
* then `await()` on the calling thread (as
|
|
* described above)
|
|
*/
|
|
Result result = myPromise.await();
|
|
|
|
/**
|
|
* One can also just start a promise without awaiting it,
|
|
* however the result will have to be grabbed manually later
|
|
*/
|
|
myPromise.execute();
|
|
|
|
/**
|
|
* The status of a promise can be checked
|
|
*
|
|
* TODO: There should be a version
|
|
*/
|
|
if(myPromise.state == State.Finished)
|
|
{
|
|
|
|
}
|
|
|
|
/**
|
|
* You can call await (it won't start it again)
|
|
* but will rather sleep like await first call.
|
|
*
|
|
* If it has finished then result is returned.
|
|
* It can be called over and over and the result
|
|
* will just be returned.

Result result = myPromise.await();
