io.deephaven.web.client.api.impl.TicketAndPromise<T>

All Implemented Interfaces:

elemental2.promise.IThenable<T>

public class TicketAndPromise<T>
extends Object
implements elemental2.promise.IThenable<T>

Pair of ticket and the promise that indicates it has been resolved. Tickets are usable before they are resolved, but to ensure that all operations completed successfully, the promise should be used to handle errors.

then

public <V> TicketAndPromise<V> then(elemental2.promise.IThenable.ThenOnFulfilledCallbackFn<? super T,? extends V> onFulfilled)

Specified by:

then in interface elemental2.promise.IThenable<T>

race

public <V> TicketAndPromise<V> race(JsFunction<Ticket,elemental2.promise.IThenable<V>> racedCall)

Rather than waiting for the original promise to succeed, lets the caller start a new call based only on the original ticket. The intent of "race" here is unlike Promise.race(), where the first to succeed should resolve - instead, this raced call will be sent to the server even though the previous call has not successfully returned, and the server is responsible for ensuring they happen in the correct order.

Type Parameters:

V - type of the next call to perform

Parameters:

racedCall - the call to perform at the same time that any pending call is happening

Returns:

a new TicketAndPromise that will resolve when all work is successful

then

public <V> elemental2.promise.IThenable<V> then(elemental2.promise.IThenable.ThenOnFulfilledCallbackFn<? super T,? extends V> onFulfilled,

release
