Interface AsyncNodeObserver

Namespace

IceGrid

Assembly

IceGrid.dll

Monitors changes to the state of the nodes.

[SliceTypeId("::IceGrid::NodeObserver")]
public interface AsyncNodeObserver : Object

Inherited Members

Object.dispatchAsync(IncomingRequest)

Object.ice_isA(string, Current)

Object.ice_ping(Current)

Object.ice_ids(Current)

Object.ice_id(Current)

Object.ice_staticId()

Remarks

This Async interface maps each Slice operation to an asynchronous method that returns a Task. Your servant class implements this interface by deriving fromAsyncNodeObserverDisp_ or from the Disp_ class for a derived interface. The Slice compiler generated this skeleton interface from Slice interface ::IceGrid::NodeObserver.
