IpClientChannel

Overview

The IpClientChannel internal abstract class is used as base for both the IpTcpClientChannel and the IpHttpClientChannel classes. The sole purpose of this class is to provide several protected helper methods (described below) to simplify the routing of transfer progress events of the underlying Internet Pack-based connections to the current instance of the ClientChannel.

Location


 

constructor  protected

Creates a new instance of the IpClientChannel class.

This method should never be called directly, because the IpClientChannel class is an abstract class and cannot be instantiated directly.

 

constructor

 

IpClientChannel()

 

Sub New()

AfterReceiveStream    (declared in Channel)

This event is triggered by client and server channels directly after a request or response stream has been received and before the stream gets parsed into a message. User code can assign handlers to this event to process, inspect or modify incoming messages, before they get handled by the Remoting SDK framework. The passed Stream is a MemoryStream and may be modified.

If no handlers are assigned to the AfterReceiveStream event, the message will load the data directly from the incoming medium (usually the network stream); assigning event handlers to AfterReceiveStream will induce a slight overhead as the data will first be copied into a local memory buffer for the event handler. This should not have any noticeably effect except for very large messages or on resource-limited systems such as Compact Framework Clients, but if utmost performance is important, take this note into consideration.

OnException    (declared in ClientChannel)

This event is raised if an exception occurs during the execution of a remote request through the channel.

This way, your client can recover from a timed-out session to automatically logging in again, without the calling code having to consider the handling of SessionNotFoundExceptions manually.

This event is triggered by client and server channels directly after a request or response stream has been received and before the stream gets parsed into a message. User code can assign handlers to this event to process, inspect or modify incoming messages, before they get handled by the Remoting SDK framework. The passed Stream is a MemoryStream and may be modified.

If no handlers are assigned to the AfterReceiveStream event, the message will load the data directly from the incoming medium (usually the network stream); assigning event handlers to AfterReceiveStream will induce a slight overhead as the data will first be copied into a local memory buffer for the event handler. This should not have any noticeably effect except for very large messages or on resource-limited systems such as Compact Framework Clients, but if utmost performance is important, take this note into consideration.
