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

220</dt>
221<dd>
222Returns the <code>urxvt::term</code> object associated with this instance of the
223extension. This member <em>must not</em> be changed in any way.

227</dt>
228<dd>
229Dynamically enable the given hooks (named without the <code>on_</code> prefix) for
230this extension, replacing any previous hook. This is useful when you want
231to overwrite time-critical hooks only temporarily.

372not always immediately.
