<a name="libpeas-PeasExtension.description"></a><h2>Description</h2>
<p><a class="link" href="libpeas-PeasExtension.html#PeasExtension" title="PeasExtension"><span class="type">PeasExtension</span></a> is a proxy class used to access actual extensions
implemented using various languages.  As such, the application writer will
use <a class="link" href="libpeas-PeasExtension.html#PeasExtension" title="PeasExtension"><span class="type">PeasExtension</span></a> instances to call methods on extension provided by
loaded plugins.</p>
<p>To properly use the proxy instances, you will need GObject-introspection
data for the <span class="type">GInterface</span> or <span class="type">GObjectClass</span> you want to use as an extension
point.  For instance, if you wish to use <a class="link" href="PeasActivatable.html" title="PeasActivatable"><span class="type">PeasActivatable</span></a>, you will need to
put the following code excerpt in the engine initialization code, in order
to load the required "Peas" typelib:</p>
<div class="informalexample"><pre class="programlisting">
g_irepository_require (g_irepository_get_default (),
                       "Peas", "1.0", 0, NULL);
</pre></div>
<p></p>
<p>You should proceed the same way for any namespace which provides interfaces
you want to use as extension points. GObject-introspection data is required
for all the supported languages, even for C.</p>
<p><a class="link" href="libpeas-PeasExtension.html#PeasExtension" title="PeasExtension"><span class="type">PeasExtension</span></a> does not provide any way to access the underlying object.
The main reason is that some loaders may not rely on proper GObject
inheritance for the definition of extensions, and hence it would not be
possible for libpeas to provide a functional GObject instance at all.
Another reason is that it makes reference counting issues easier to deal
with.</p>

<p>Call a method of the object behind <em class="parameter"><code>extension</code></em>

<p>The arguments provided to this functions should be of the same type as
those defined in the <span class="type">GInterface</span> or <span class="type">GObjectClass</span> used as a base for the
proxied extension. They should be provided in the same order, and if its
return type is not void, then a pointer to a variable of that type should
be passed as the last argument.</p>
<p>For instance, if the method prototype is:</p>
<div class="informalexample"><pre class="programlisting">
you should call peas_extension_call() this way:
|[ peas_extension_call (extension, "my_method", "some_str", obj, &amp;gint_var); ]|

This function will not do anything if the introspection data for the proxied
object's class has not been loaded previously through g_irepository_require().
