Interface Result<T>

Result of an asynchronous function that may be available immediately or some time later. Similar to Deferred.

interface Result<T> {
    get(): T;
    isPending(): boolean;
    then(callback: (p1: T) => void): void;
    thenAsync<T1>(callback: (p1: T) => Result<T1>): Result<T1>;
    thenFinish(frame: Frame<T>): void;
    thenReturn<T1>(result: T1): Result<T1>;
}

isPending

isPending(): boolean
Check if this Result is still pending.

Returns boolean

thenAsync

thenAsync<T1>(callback: (p1: T) => Result<T1>): Result<T1>

thenFinish

thenFinish(frame: Frame<T>): void
Finish given frame with the result value when result becomes ready.
Parameters
- frame: Frame<T>
Returns void
