220<h2><a name="extension_objects">Extension Objects</a></h2>
221<p>Very perl extension is a perl class. A separate perl object is created
222for each terminal and each extension and passed as the first parameter to
223hooks. So extensions can use their <code>$self</code> object without having to think
224about other extensions, with the exception of methods and members that
225begin with an underscore character <code>_</code>: these are reserved for internal
226use.</p>
227<p>Although it isn't a <code>urxvt::term</code> object, you can call all methods of the
228<code>urxvt::term</code> class on this object.</p>
229<p>It has the following methods and data members:</p>

241Dynamically enable the given hooks (named without the <code>on_</code> prefix) for
242this extension, replacing any previous hook. This is useful when you want
243to overwrite time-critical hooks only temporarily.
