IVs Enum Async
IVs Enum Async
Implemented by enumerators supporting asynchronous behavior.

Public Interface IVsAsyncEnum
You should query for the interface and advise any callback interfaces before calling the Next method. Synchronous enumerators can support
IVsAsyncEnum, and the same requirements apply (the callback interfaces are added prior to normal direct manipulation of the enumerator via its primary interface). However, the entire count of elements available is passed as
cElementsAvailable to OnDataAvailable, and
fIsComplete is set to
Stopping an asynchronous enumerator is itself an asynchronous operation. When the enumerator is stopped, an OnDataAvailable event is fired, with
cElementsAvailable set to zero, and
fIsComplete set to
true to the Stop call causes the thread to block until the enumerator has fired its final OnDataAvailable event.
|AdviseAsyncEnumCallback(IVsAsyncEnumCallback, UInt32) AdviseAsyncEnumCallback(IVsAsyncEnumCallback, UInt32) AdviseAsyncEnumCallback(IVsAsyncEnumCallback, UInt32)||
Enables the client to receive events about changes to the asynchronous enumeration.
|Stop(Int32) Stop(Int32) Stop(Int32)||
Requests that the asynchronous enumeration be stopped.
|UnadviseAsyncEnumCallback(UInt32) UnadviseAsyncEnumCallback(UInt32) UnadviseAsyncEnumCallback(UInt32)||
Indicates the client is no longer interested in receiving asynchronous enumeration events.
