<div class="block">An installed bundle in the Framework.
<p>
A <code>Bundle</code> object is the access point to define the lifecycle of an
installed bundle. Each bundle installed in the OSGi environment must have an
associated <code>Bundle</code> object.
<p>
A bundle must have a unique identity, a <code>long</code>, chosen by the
Framework. This identity must not change during the lifecycle of a bundle,
even when the bundle is updated. Uninstalling and then reinstalling the
bundle must create a new unique identity.
<p>
A bundle can be in one of six states:
<ul>
<li><a href="../../../org/osgi/framework/Bundle.html#UNINSTALLED"><code>UNINSTALLED</code></a>
<li><a href="../../../org/osgi/framework/Bundle.html#INSTALLED"><code>INSTALLED</code></a>
<li><a href="../../../org/osgi/framework/Bundle.html#RESOLVED"><code>RESOLVED</code></a>
<li><a href="../../../org/osgi/framework/Bundle.html#STARTING"><code>STARTING</code></a>
<li><a href="../../../org/osgi/framework/Bundle.html#STOPPING"><code>STOPPING</code></a>
<li><a href="../../../org/osgi/framework/Bundle.html#ACTIVE"><code>ACTIVE</code></a>
</ul>
<p>
Values assigned to these states have no specified ordering; they represent
bit values that may be ORed together to determine if a bundle is in one of
the valid states.
<p>
A bundle should only have active threads of execution when its state is one
of <code>STARTING</code>,<code>ACTIVE</code>, or <code>STOPPING</code>. An <code>UNINSTALLED</code> bundle can not be set to another state; it is a zombie and can
only be reached because references are kept somewhere.
<p>
The Framework is the only entity that is allowed to create <code>Bundle</code>
objects, and these objects are only valid within the Framework that created
them.
<p>
Bundles have a natural ordering such that if two <code>Bundle</code>s have the
same <a href="../../../org/osgi/framework/Bundle.html#getBundleId()"><code>bundle id</code></a> they are equal. A <code>Bundle</code> is
less than another <code>Bundle</code> if it has a lower <a href="../../../org/osgi/framework/Bundle.html#getBundleId()"><code>bundle id</code></a> and is greater if it has a higher bundle id.</div>

into account that the "contents" of this bundle can be extended

possibly changing the set of URLs returned by this method. If this bundle
