201<h2><a name="extension_objects">Extension Objects</a></h2>
202<p>Very perl extension is a perl class. A separate perl object is created
203for each terminal and each extension and passed as the first parameter to
204hooks. So extensions can use their <code>$self</code> object without having to think
205about other extensions, with the exception of methods and members that
206begin with an underscore character <code>_</code>: these are reserved for internal
207use.</p>
208<p>Although it isn't a <code>urxvt::term</code> object, you can call all methods of the
209<code>urxvt::term</code> class on this object.</p>
210<p>It has the following methods and data members:</p>

216extension. This member <em>must not</em> be changed in any way.

221<dd>
222Dynamically enable the given hooks (named without the <code>on_</code> prefix) for
223this extension, replacing any previous hook. This is useful when you want
224to overwrite time-critical hooks only temporarily.
