System.ServiceModel 4.0.0.0 System.ServiceModel.Channels.CommunicationObject System.ServiceModel.Channels.IChannel System.ServiceModel.IDefaultCommunicationTimeouts

The class provides an abstract base class implementation of the interface. It also requires that each channel be associated with a channel manager. Note that the only constructor available for creating instances of requires a input parameter.

State changes are managed by inheriting from the implementation of the state machine.

The gets its default communication timeouts for the open, close, send and receive operations from the associated with it.

The also manages the manager for you. In addition to exposing a reference to the manager, the base class also notifies the manager when channels are created and destroyed. But the reference to the manager is only good until the channel is destroyed.

Even if you do use the base class, you must still provide behaviors for opening and closing the channel. The default implementations of these methods do not provide useful information.

You must also make sure to override whenever you implement a channel. is an excellent way to communicate information along the channel stack without having to know what channels are below you, or what channels above you may perform queries. Define interfaces that can be queried for available information. Whenever you do not recognize the type argument for , delegate down to the next channel in the stack or return null if you are creating a new transport channel at the bottom of the stack.

Provides the base implementation for custom channels.

- Constructor
  4.0.0.0
  To be added.

  Note that the only constructor available for creating instances of requires a input parameter.

  Initializes a new instance of the class.

- Property
  4.0.0.0
  System.TimeSpan To be added.

  Gets the associated with for the channel.

  All operations that are potentially lengthy must have a timeout. Methods that do not take explicit timeouts, must delegate to those methods with default timeouts or must not do any work that blocks. Timeouts are the total limit for high-level operations for which they are to complete, so any retries must be limited to the time not already accessed by earlier tries.

  Gets the default interval of time provided for a close operation to complete.

- Method
  4.0.0.0
  T ReferenceTypeConstraint

  Use this to request a typed object such as an interface for setting properties or getting status from the appropriate layer in the channel stack. If a layer supports returning the requested object, it returns it. If not, it delegates the call down to the next layer in the stack. If it gets to the bottom of the stack and no channel layer supported the requested object, then the method returns null.

  You must also make sure to override whenever you implement a channel. is an excellent way to communicate information along the channel stack without having to know what channels are below you, or what channels above you may perform queries. Define interfaces that can be queried for available information. Whenever you do not recognize the type argument for , delegate down to the next channel in the stack or return null if you are creating a new transport channel at the bottom of the stack.

  Returns the typed object requested, if present, from the appropriate layer in the channel stack.

  The typed object requested, if it is present, or null, if it is not.

  The typed object for which the method is querying.

  Every must have a associated with it.

  Gets the channel manager that is associated with the current channel.
