145=head2 Extension Objects
146
147Very perl extension is a perl class. A separate perl object is created
148for each terminal and each extension and passed as the first parameter to
149hooks. So extensions can use their C<$self> object without having to think
150about other extensions, with the exception of methods and members that
151begin with an underscore character C<_>: these are reserved for internal
152use.
153
154Although it isn't a C<urxvt::term> object, you can call all methods of the
155C<urxvt::term> class on this object.
156
157It has the following methods and data members:

164extension. This member I<must not> be changed in any way.
165
166=item $self->enable ($hook_name => $cb, [$hook_name => $cb..])
167
168Dynamically enable the given hooks (named without the C<on_> prefix) for
169this extension, replacing any previous hook. This is useful when you want
170to overwrite time-critical hooks only temporarily.

127object that is shared between all packages is stored in the C<term>

692The sole purpose of this class is to deliver an interface to the
693C<AnyEvent> module - any module using it will work inside urxvt without
694further programming. The only exception is that you cannot wait on
695condition variables, but non-blocking condvar use is ok. What this means
696is that you cannot use blocking APIs, but the non-blocking variant should
697work.

1309=item $success = $term->grab ($eventtime[, $sync])
1310
1311Calls XGrabPointer and XGrabKeyboard in asynchronous (default) or
1312synchronous (C<$sync> is true). Also remembers the grab timestampe.
1313
1314=item $term->allow_events_async
1315
1316Calls XAllowEvents with AsyncBoth for the most recent grab.
1317
1318=item $term->allow_events_sync
1319
1320Calls XAllowEvents with SyncBoth for the most recent grab.
1321
1322=item $term->allow_events_replay
1323
1324Calls XAllowEvents with both ReplayPointer and ReplayKeyboard for the most
1325recent grab.
1326
1327=item $term->ungrab
1328
1329Calls XUngrab for the most recent grab. Is called automatically on
1330evaluation errors, as it is better to lose the grab in the error case as
1331the session.
