ChannelDispatcherBase Class

Definition

Abstract base class for the channel dispatcher that accepts channels and associates them with a service.

Remarks

This is used by developers who want to keep the Windows Communication Foundation (WCF) programming model but replace the system-provided runtime. Such applications will pull messages out of channels and handle them directly with user-defined dispatchers. To use ChannelDispatcherBase , create a class derived from it, extend ServiceHost and override InitializeRuntime, adding instances of your class derived from ChannelDispatcherBase to ChannelDispatchers.

The IChannelListener and the ServiceHost, associated with the ChannelDispatcherBase object are available for inspection or modification through the Listener and Host respectively.

ServiceHost calls the Attach(ServiceHostBase) or Detach(ServiceHostBase) methods when adding or removing a ChannelDispatcherBase item from its ChannelDispatchers collection.

ServiceHost calls the CloseInput during shutdown before closing InstanceContexts. Windows Communication Foundation (WCF) uses this call to close datagram channels and wait for all messages to get to an InstanceContext.

Constructors

ChannelDispatcherBase()

Initializes a new instance of the ChannelDispatcherBase class.

Properties

DefaultCloseTimeout

When overridden in a derived class, gets the default interval of time provided for a close operation to complete.

(Inherited from CommunicationObject)
DefaultOpenTimeout

When overridden in a derived class, gets the default interval of time provided for an open operation to complete.

(Inherited from CommunicationObject)
Host

When overridden in a derived class, gets the service host associated with the channel dispatcher.

IsDisposed

Gets a value that indicates whether the communication object has been disposed.

(Inherited from CommunicationObject)
Listener

When overridden in a derived class, gets the channel listener associated with the channel dispatcher.

State

Gets a value that indicates the current state of the communication object.

(Inherited from CommunicationObject)
ThisLock

Gets the mutually exclusive lock that protects the class instance during a state transition.

(Inherited from CommunicationObject)

Methods
