Class ExternalComponent

java.lang.Object

org.jivesoftware.whack.ExternalComponent

All Implemented Interfaces:

org.xmpp.component.Component

public class ExternalComponent
extends Object
implements org.xmpp.component.Component

ExternalComponents are responsible for connecting and authenticating with a remote server and for sending and processing received packets. In fact, an ExternalComponent is a wrapper on a Component that provides remote connection capabilities. The actual processing of the packets is done by the wrapped Component.

Method Detail

connect

public void connect(String host,
           int port,
           String subdomain)
             throws org.xmpp.component.ComponentException

Generates a connection with the server and tries to authenticate. If an error occurs in any of the steps then a ComponentException is thrown.

Parameters:

host - the host to connect with.

port - the port to use.

subdomain - the subdomain that this component will be handling.

Throws:

org.xmpp.component.ComponentException - if an error happens during the connection and authentication steps.
