<B>Datashare API for Channel Lifecycle Events</B>

</TD>
<TD vAlign=top width="70%">
<p><br></p>
<P>IChannel lifecycle events are now delivered via: <a href="http://www.eclipse.org/ecf/org.eclipse.ecf.docs/api/org/eclipse/ecf/datashare/IChannelContainerListener.html">IChannelContainerListener</a>.
Methods <a href="http://www.eclipse.org/ecf/org.eclipse.ecf.docs/api/org/eclipse/ecf/datashare/IAbstractChannelContainer.html#addChannelContainerListener(org.eclipse.ecf.datashare.IChannelContainerListener)">IChannelContainer.addChannelContainerListener</a>
and <a href="http://www.eclipse.org/ecf/org.eclipse.ecf.docs/api/org/eclipse/ecf/datashare/IAbstractChannelContainer.html#removeChannelContainerListener(org.eclipse.ecf.datashare.IChannelContainerListener)">IChannelContainer.removeChannelContainerListener</a>
have been added to <b>IChannelContainer</b> allow the registration of listeners prior to the creation of <b>IChannels</b> within the <b>IChannelContainer</b>.
</p><p>Datashare provider implementations <b>must</b> deliver IChannelContainerListeners instances of the following events when IChannel instances are
created, either via local calls to IChannelContainer.createChannel, or via remote calls to create replica <b>IChannels</b>. In either the local or remote case,
the following events are to be
delivered to IChannelContainerListeners:</p>
<p></p>
<p><b>IChannelContainerChannelActivatedEvent</b> - delivered when an IChannel within this container is first activated</p>
<p><b>IChannelContainerChannelDeactivatedEvent</b> - delivered when an IChannel within this container is deactivated</p>
Instances of these events must be delivered synchronously to all <b>IChannelContainerListeners</b>. In the case of the <b>IChannelContainerChannelActivatedEvent</b>, the event should
be delivered to all <b>IChannelContainerListeners</b> before any other messages are delivered to the channel.</p>
<p>Note that the reception of the <b>IChannelContainerChannelActivatedEvent</b> can be responded to by (for example), setting the IChannelListener on
the channel to the desired channel message handler (for handling <b>IChannelMessageEvents</b>).
</p>
<p>See example test code in the <b>org.eclipse.ecf.test.datashare</b> plugin, in the <b>DatashareFixedChannelTest</b>, <b>DatashareDynamicChannelTest</b>, and <b>DatashareCustomChannelTest</b> test classes.</p>
