IAsyncInfo class

Supports asynchronous actions and operations. IAsyncInfo is a base interface for IAsyncAction, IAsyncActionWithProgress<TProgress>, IAsyncOperation<TResult> and IAsyncOperationWithProgress<TResult,TProgress>, each of which support combinations of return type and progress for an asynchronous method.

Methods

addRef() → int
Increments the reference count for an interface pointer to a COM object.
inherited
cancel() → void
cast<T extends IUnknown>(T creator(Pointer<COMObject>), String iid) → T

Available on IUnknown, provided by the IUnknownHelpers extension

Casts this COM object to an interface specified in iid.

inherited
getRuntimeClassName(Pointer<IntPtr> className) → int
inherited
getTrustLevel(Pointer<Int32> trustLevel) → int
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
queryInterface(Pointer<GUID> riid, Pointer<Pointer<NativeType>> ppvObject) → int
Queries a COM object for a pointer to one of its interface; identifying the interface by a reference to its interface identifier (IID).
inherited
release() → int

inherited
toInterface(String iid) → Pointer<COMObject>
Cast an existing COM object to a specified interface.
inherited
toString() → String
A string representation of this object.
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.
