210<h2><a name="extension_objects">Extension Objects</a></h2>
211<p>Very perl extension is a perl class. A separate perl object is created
212for each terminal and each extension and passed as the first parameter to
213hooks. So extensions can use their <code>$self</code> object without having to think
214about other extensions, with the exception of methods and members that
215begin with an underscore character <code>_</code>: these are reserved for internal
216use.</p>
217<p>Although it isn't a <code>urxvt::term</code> object, you can call all methods of the
218<code>urxvt::term</code> class on this object.</p>
219<p>It has the following methods and data members:</p>

232this extension, replacing any previous hook. This is useful when you want
233to overwrite time-critical hooks only temporarily.
