Class goog.async.DeferredList

Constructs an object that waits on the results of multiple asynchronous operations and marshals the results. It is itself a Deferred, and sends results to its registered callback chain. Each instance is single use and may only fire once. Unless overridden by one of the options below, the DeferredList will wait for a result from every input Deferred. The results are stored in a list of two-element arrays as [success, result], where success is whether that result was from a callback or errback. Once all results are available, the DeferredList's callback chain is invoked with the full result list.

extends goog.async.Deferred

Instance Method Summary
	`errback(<Any Type> result)` Record that this operation failed with an error, and send the error to all registered errback functions.
	`handleCallback_(number index, boolean success, <Any Type> result) ⇒ <Any Type>` Registers the result from an input deferred callback or errback. The result is returned and may be passed to additional handlers in the callback chain.

Static Method Summary
	`gatherResults(!Array list) ⇒ !goog.async.DeferredList` Creates a `DeferredList` that gathers results from multiple `Deferred` inputs. If all inputs succeed, the callback is fired with the list of results as a flat array. If any input fails, the errback is fired with the error.
