IClientChannelSinkProvider Interface

 

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

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

[ComVisibleAttribute(true)]
public interface IClientChannelSinkProvider

NameDescription
System_CAPS_pubpropertyNext

Gets or sets the next sink provider in the channel sink provider chain.

NameDescription
System_CAPS_pubmethodCreateSink(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.

The following code example illustrates an implementation of this interface.

public class ClientSinkProvider : IClientChannelSinkProvider
{

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

    public IClientChannelSinkProvider Next
    {
        [SecurityPermission(SecurityAction.LinkDemand, Flags = SecurityPermissionFlag.Infrastructure)]
        get
        {
            return(nextProvider);
        }
        [SecurityPermission(SecurityAction.LinkDemand, Flags = SecurityPermissionFlag.Infrastructure)]
        set
        {
            nextProvider = value;
        }
    }

    [SecurityPermission(SecurityAction.LinkDemand, Flags = SecurityPermissionFlag.Infrastructure)]
    public 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( new 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.
    public ClientSinkProvider (IDictionary properties, ICollection providerData) {}

}

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