class Deferred<T>
- All implemented interfaces:
webdriver.promise.Thenable<T>
Represents a value that will be resolved at some point in the future. This class represents the protected "producer" half of a Promise - each Deferred has a promise property that may be returned to consumers for registering callbacks, reserving the ability to resolve the deferred to the producer.
If this Deferred is rejected and there are no listeners registered before the next turn of the event loop, the rejection will be passed to the webdriver.promise.ControlFlow as an unhandled failure.
new Deferred(opt_flow)
Parameters
- opt_flow
?webdriver.promise.ControlFlow= The control flow this instance was created under. This should only be provided during unit tests.
Instance Methods
fulfill(opt_value)code »
Resolves this deferred with the given value. It is safe to call this as a normal function (with no bound "this").
Parameters
- opt_value
?(T|IThenable<T>|{then: Function})= The fulfilled value.
reject(opt_reason)code »
Rejects this promise with the given reason. It is safe to call this as a normal function (with no bound "this").
Parameters
- opt_reason
*= The rejection reason.
then(opt_cb, opt_eb)code »
