<h4>ServicePermission</h4>
<pre>public ServicePermission(java.lang.String name,
java.lang.String actions)</pre>
<div class="block">Create a new ServicePermission.
<p>
The name of the service is specified as a fully qualified class name.
Wildcards may be used.
<pre>
name ::= <class name> | <class name ending in ".*"> | *
</pre>
Examples:
<pre>
org.osgi.service.http.HttpService
org.osgi.service.http.*
*
</pre>
For the <code>get</code> action, the name can also be a filter expression. The
filter gives access to the service properties as well as the following
attributes:
<ul>
<li>signer - A Distinguished Name chain used to sign the bundle
publishing the service. Wildcards in a DN are not matched according to
the filter string rules, but according to the rules defined for a DN
chain.</li>
<li>location - The location of the bundle publishing the service.</li>
<li>id - The bundle ID of the bundle publishing the service.</li>
<li>name - The symbolic name of the bundle publishing the service.</li>
</ul>
Since the above attribute names may conflict with service property names
used by a service, you can prefix an attribute name with '@' in the
filter expression to match against the service property and not one of
the above attributes. Filter attribute names are processed in a case
sensitive manner unless the attribute references a service property.
Service properties names are case insensitive.
<p>
There are two possible actions: <code>get</code> and <code>register</code>. The
<code>get</code> permission allows the owner of this permission to obtain a
service with this name. The <code>register</code> permission allows the bundle
to register a service under that name.</div>
