The extension object is responsible for returning a number of
interesting objects through its methods. These objects are meant to be
used for interacting with the component. One of these is
getDispatcher which lets us retrieve the component's Dispatcher object.
Your extension can have a custom dispatcher class,
\,
where
My\Component\Example\Dispatcher\Dispatcher\
is your component's prefix. If this class exists, an object instance of
it is returned.My\Component\Example
If your extension does not have a dispatcher an instance of the
default Joomla\CMS\Dispatcher\ComponentDispatcher
(site and administrator applications) or
Joomla\CMS\Dispatcher\ApiDispatcher (API
application) will be created and returned instead.
