<div class="wiki-content maincontent"><h2>Life cycle of Channels</h2>

<p>Blaze Channels are in one of five states:</p>

<h3>Constructed - the Channel isn't initialized or has been shutDown</h3>

<h3>initialized - </h3>
<p> you can explicitly initialize a Channel by invoking its init() method. At this point its Configuration is set</p>

 BlazeChannelFactory factory = new BlazeChannelFactory();
 BlazeChannel channel = factory.createChannel();
 channel.init();
</plain-text-body></structured-macro>

<h3>started - </h3>
<p> this will implicitly initialize the channel and start the Channel's underlying communication with its peers:</p>

<structured-macro ac:macro-id="4b16db1d-9359-4600-8d74-4fc58d51bec0" ac:name="code" ac:schema-version="1"><plain-text-body>
 BlazeChannelFactory factory = new BlazeChannelFactory();
 BlazeChannel channel = factory.createChannel();
 channel.start();
</plain-text-body></structured-macro>

<h3>stopped - </h3>
<p> this will stop communication - however you are able to re-start the channel at a latter point</p>

<structured-macro ac:macro-id="268ac83c-3aac-47ec-a2bb-82fb9c7ef9e6" ac:name="code" ac:schema-version="1"><plain-text-body>
 BlazeChannelFactory factory = new BlazeChannelFactory();
 BlazeChannel channel = factory.createChannel();
 channel.stop();
 // do something else
 ...
 //re-start
 channel.start();
</plain-text-body></structured-macro>

<h3>shut down</h3>
<ul class="alternate"><li>this will implicitly call stop() - and de-construct the channel. It is possible to re-initialize the channel again - and it is recommend that to apply configuration changes to the channel - it be shut down and re-started - e.g.</li></ul>

 BlazeChannelFactory factory = new BlazeChannelFactory();
 BlazeChannel channel = factory.createChannel();
 channel.shutDown();
 // change the congiguration
 channel.getConfiguration().setBroadcastURI("tcp://localhost:60661");
 //re-start
 channel.start();
