implements
PromiseAdapter
Allows changing order of field resolution even in sync environments (by leveraging queue of deferreds and promises).
Interfaces, Classes and Traits
- PromiseAdapter
- Provides a means for integration of async PHP platforms ([related docs](data-fetching.md#async-php)).
Table of Contents
- all() : Promise
- Given an iterable of promises (or values), returns a promise that is fulfilled when all the items in the iterable are fulfilled.
- convertThenable() : Promise
- Converts thenable of the underlying platform into Automattic\WooCommerce\Vendor\GraphQL\Executor\Promise\Promise instance.
- create() : Promise
- Creates a Promise from the given resolver callable.
- createFulfilled() : Promise
- Creates a fulfilled Promise for a value if the value is not a promise.
- createRejected() : Promise
- Creates a rejected promise for a reason if the reason is not a promise.
- isThenable() : bool
- Is the value a promise or a deferred of the underlying platform?
- then() : Promise
- Accepts our Promise wrapper, extracts adopted promise out of it and executes actual `then` logic described in Promises/A+ specs. Then returns new wrapped instance of Automattic\WooCommerce\Vendor\GraphQL\Executor\Promise\Promise.
- wait() : mixed
- Synchronously wait when promise completes.
- beforeWait() : void
- Execute just before starting to run promise completion.
- onWait() : void
- Execute while running promise completion.

Promise —isThenable()
Is the value a promise or a deferred of the underlying platform?
public
isThenable(mixed $value) : bool
Parameters
