IClientChannelSinkProvider Interface

.NET Framework (current version)

Creates client channel sinks for the client channel through which remoting messages flow.

Namespace: System.Runtime.Remoting.Channels
Assembly: mscorlib (in mscorlib.dll)

Syntax

[ComVisibleAttribute(true)]
public interface class IClientChannelSinkProvider

Properties

	Name	Description
	Next	Gets or sets the next sink provider in the channel sink provider chain.

Methods

	Name	Description
	CreateSink(IChannelSender^, String^, Object^)	Creates a sink chain.

Channel sinks are connected to a client channel through implementations of the IClientChannelSinkProvider interface. All the remoting client channels provide constructors that take a IClientChannelSinkProvider as a parameter.

Channel sink providers are stored in a chain, and the user is responsible for chaining all channel sink providers together before passing the outer one to the channel constructor. IClientChannelSinkProvider provides a property called Next for this purpose.

When multiple channel sink providers are specified in a configuration file, the remoting infrastructure will chain them together in the order they are found in the configuration file. The channel sink providers will be created when the channel is created during the RemotingConfiguration::Configure call.

Examples

The following code example illustrates an implementation of this interface.

C++

[System::Security::Permissions::PermissionSet(System::Security::
   Permissions::SecurityAction::Demand, Name = "FullTrust")]
public ref class ClientSinkProvider: public IClientChannelSinkProvider
{
private:

   // The next provider in the chain.
   IClientChannelSinkProvider^ nextProvider;

public:
   property IClientChannelSinkProvider^ Next 
   {
      virtual IClientChannelSinkProvider^ get()
      {
         return (nextProvider);
      }

      virtual void set( IClientChannelSinkProvider^ value )
      {
         nextProvider = value;
      }
   }

   virtual IClientChannelSink^ CreateSink( IChannelSender^ channel, String^ url, Object^ remoteChannelData )
   {
      Console::WriteLine( "Creating ClientSink for {0}", url );

      // Create the next sink in the chain.
      IClientChannelSink^ nextSink = nextProvider->CreateSink( channel, url, remoteChannelData );

      // Hook our sink up to it.
      return (gcnew ClientSink( nextSink ));
   }

   // This constructor is required in order to use the provider in file-based configuration.
   // It need not do anything unless you want to use the information in the parameters.
   ClientSinkProvider( IDictionary^ /*properties*/, ICollection^ /*providerData*/ ){}
};

See the IClientChannelSink interface documentation for an example of the corresponding client sink implementation.
