IAsyncOperation<TResult> class abstract interface

Represents an asynchronous operation, which returns a result upon completion. This is the return type for many Windows Runtime asynchronous methods that have results but don't report progress.

Constructors

IAsyncOperation.fromPtr(Pointer<COMObject> ptr, {TResult creator(Pointer<COMObject>)?, TResult enumCreator(int)?, DoubleType? doubleType, IntType? intType})
Creates an instance of IAsyncOperation from the given ptr.

inherited
tryCast<T extends IUnknown>(T creator(Pointer<COMObject>), String iid) → T?

Available on IUnknown, provided by the IUnknownHelpers extension

Tries to cast this COM object to an interface specified in iid.

Operators

operator ==(Object other) → bool
The equality operator.
