return	React\Promise\Promise	A promise resolved to $value

Example #1

File: PromiseFactoryTest.php Project: voryx/Rx.PHP

 /**
  * @test
  */
 public function from_promise_success()
 {
     $source = PromiseFactory::toObservable(function () {
         return Promise::resolved(42);
     });
     $results = $this->scheduler->startWithCreate(function () use($source) {
         return $source;
     });
     $this->assertMessages(array(onNext(200, 42), onCompleted(200)), $results->getMessages());
 }

Example #2

File: PromiseToObservableTest.php Project: voryx/Rx.PHP

 /**
  * @test
  *
  */
 public function from_promise_success()
 {
     $p = Promise::resolved(42);
     $source = Promise::toObservable($p);
     $source->subscribe(new CallbackObserver(function ($x) {
         $this->assertEquals(42, $x);
     }, function ($error) {
         $this->assertFalse(true);
     }, function () {
         $this->assertTrue(true);
     }));
 }

Example #3

File: promise-to-observable.php Project: bluetechy/Rx.PHP

<?php

require_once __DIR__ . '/../bootstrap.php';
$p = \Rx\React\Promise::resolved(42);
$source = \Rx\React\Promise::toObservable($p);
$subscription = $source->subscribe($stdoutObserver);
//Next value: 42
//Complete!
// Create a promise which rejects with an error
$p = \Rx\React\Promise::rejected(new Exception('because'));
$source2 = \Rx\React\Promise::toObservable($p);
$subscription = $source2->subscribe($createStdoutObserver());
//Exception: because

Example #4

File: defer.php Project: Katakeyni/Rx.PHP

<?php

require_once __DIR__ . '/../bootstrap.php';
/* Using a promise */
$source = \Rx\React\PromiseFactory::toObservable(function () {
    return \Rx\React\Promise::resolved(42);
});
$subscription = $source->subscribe($createStdoutObserver());
//Next value: 42
//Complete!
