140=head2 Extension Objects
141
142Very perl extension is a perl class. A separate perl object is created
143for each terminal and each extension and passed as the first parameter to
144hooks. So extensions can use their C<$self> object without having to think
145about other extensions, with the exception of methods and members that
146begin with an underscore character C<_>: these are reserved for internal
147use.
148
149Although it isn't a C<urxvt::term> object, you can call all methods of the
150C<urxvt::term> class on this object.
151
152It has the following methods and data members:
153

155
156=item $urxvt_term = $self->{term}

158Returns the C<urxvt::term> object associated with this instance of the
159extension. This member I<must not> be changed in any way.
160
161=item $self->enable ($hook_name => $cb, [$hook_name => $cb..])
162
163Dynamically enable the given hooks (named without the C<on_> prefix) for
164this extension, replacing any previous hook. This is useful when you want
165to overwrite time-critical hooks only temporarily.
166
167=item $self->disable ($hook_name[, $hook_name..])

169Dynamically disable the given hooks.
