<DD>Find hook method. This method is called for the following:
<ul>
<li>Bundle find operations using <A HREF="../../../../../org/osgi/framework/BundleContext.html#getBundle(long)"><CODE>BundleContext.getBundle(long)</CODE></A>
and <A HREF="../../../../../org/osgi/framework/BundleContext.html#getBundles()"><CODE>BundleContext.getBundles()</CODE></A> methods. The find method can
filter the result of the find operation. Note that a find operation using
the <A HREF="../../../../../org/osgi/framework/BundleContext.html#getBundle(java.lang.String)"><CODE>BundleContext.getBundle(String)</CODE></A> method does not cause the
find method to be called.</li>
<li>Bundle install operations when an existing bundle is already
installed at a given location. In this case, the find method is called to
determine if the context performing the install operation is able to find
the bundle. If the context cannot find the existing bundle then the
install operation must fail with a
<A HREF="../../../../../org/osgi/framework/BundleException.html#REJECTED_BY_HOOK"><CODE>BundleException.REJECTED_BY_HOOK</CODE></A> exception.</li>
</ul>
<P>
<DD><DL>
<DT><B>Parameters:</B><DD><CODE>context</CODE> - The bundle context of the bundle performing the find
operation.<DD><CODE>bundles</CODE> - A collection of Bundles to be returned as a result of the find
operation. The implementation of this method may remove
bundles from the collection to prevent the bundles from being
returned to the bundle performing the find operation. The
collection supports all the optional <code>Collection</code>
operations except <code>add</code> and <code>addAll</code>. Attempting
to add to the collection will result in an
<code>UnsupportedOperationException</code>. The collection is not
synchronized.</DL>
