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
| Abort() |
Causes a communication object to transition immediately from its current state into the closing state. (Inherited from CommunicationObject) |
| Attach(ServiceHostBase) |
When overridden in a derived class, attaches the channel dispatcher to a specific host. |
| BeginClose(AsyncCallback, Object) |
Begins an asynchronous operation to close a communication object. (Inherited from CommunicationObject) |
| BeginClose(TimeSpan, AsyncCallback, Object) |
Begins an asynchronous operation to close a communication object with a specified timeout. (Inherited from CommunicationObject) |
| BeginOpen(AsyncCallback, Object) |
Begins an asynchronous operation to open a communication object. (Inherited from CommunicationObject) |
| BeginOpen(TimeSpan, AsyncCallback, Object) |
Begins an asynchronous operation to open a communication object within a specified interval of time. (Inherited from CommunicationObject) |
| Close() |
Causes a communication object to transition from its current state into the closed state. (Inherited from CommunicationObject) |
| Close(TimeSpan) |
Causes a communication object to transition from its current state into the closed state within a specified interval of time. (Inherited from CommunicationObject) |
| CloseInput() |
When overridden in a derived class, removes the endpoint dispatchers associated with the channel dispatcher. |
| Detach(ServiceHostBase) |
When overridden in a derived class, detaches the channel dispatcher from a specific host. |
| EndClose(IAsyncResult) |
Completes an asynchronous operation to close a communication object. (Inherited from CommunicationObject) |
| EndOpen(IAsyncResult) |
Completes an asynchronous operation to open a communication object. (Inherited from CommunicationObject) |

| GetType() |
Gets the Type of the current instance. (Inherited from Object) |
| MemberwiseClone() |
Creates a shallow copy of the current Object. (Inherited from Object) |
| OnAbort() |
Inserts processing on a communication object after it transitions to the closing state due to the invocation of a synchronous abort operation. (Inherited from CommunicationObject) |
| OnBeginClose(TimeSpan, AsyncCallback, Object) |
Inserts processing after a communication object transitions to the closing state due to the invocation of an asynchronous close operation. (Inherited from CommunicationObject) |
| OnBeginOpen(TimeSpan, AsyncCallback, Object) |
Inserts processing on a communication object after it transitions to the opening state due to the invocation of an asynchronous open operation. (Inherited from CommunicationObject) |
| OnClose(TimeSpan) |
Inserts processing on a communication object after it transitions to the closing state due to the invocation of a synchronous close operation. (Inherited from CommunicationObject) |
| OnClosed() |
Invoked during the transition of a communication object into the closing state. (Inherited from CommunicationObject) |
| OnClosing() |
Invoked during the transition of a communication object into the closing state. (Inherited from CommunicationObject) |
| OnEndClose(IAsyncResult) |
Completes an asynchronous operation on the close of a communication object. (Inherited from CommunicationObject) |
| OnEndOpen(IAsyncResult) |
Completes an asynchronous operation on the open of a communication object. (Inherited from CommunicationObject) |
| OnFaulted() |
Inserts processing on a communication object after it transitions to the faulted state due to the invocation of a synchronous fault operation. (Inherited from CommunicationObject) |
| OnOpen(TimeSpan) |
Inserts processing on a communication object after it transitions into the opening state which must complete within a specified interval of time. (Inherited from CommunicationObject) |
| OnOpened() |
Invoked during the transition of a communication object into the opened state. (Inherited from CommunicationObject) |
| OnOpening() |
Invoked during the transition of a communication object into the opening state. (Inherited from CommunicationObject) |
| Open() |
Causes a communication object to transition from the created state into the opened state. (Inherited from CommunicationObject) |
| Open(TimeSpan) |
Causes a communication object to transition from the created state into the opened state within a specified interval of time. (Inherited from CommunicationObject) |
| ThrowIfDisposed() |
Throws an exception if the communication object is disposed. (Inherited from CommunicationObject) |
| ThrowIfDisposedOrImmutable() |
