/** @HTML
|
|
|
|
Helper class for implementing the <code>XDispatchProvider</code> interface
|
|
of the ChartController. This class handles all commands to queryDispatch and
|
|
queryDispatches in the following way:
|
|
|
|
<ul>
|
|
<li>Check if there is a cached <code>XDispatch</code> for a given command.
|
|
If so, use it.</li>
|
|
<li>Check if the command is handled by this class, e.g. Undo. If so,
|
|
return a corresponding <code>XDispatch</code> implementation, and cache
|
|
this implementation for later use</li>
|
|
<li>Otherwise send the command to the chart dispatch provider, if it
|
|
can handle this dispatch (determined by the list of commands given in
|
|
<code>setChartDispatch()</code>).</li>
|
|
</ul>
|
|
|
|
<p>The <code>XDispatch</code>Provider is designed to return different
|
|
<code>XDispatch</code> implementations for each command. This class here
|
|
decides which implementation to use for which command.</p>
|
|
|
|
<p>As most commands need much information of the controller and are
|
|
implemented there, the controller handles most of the commands itself (it
|
|
also implements <code>XDispatch</code>). Therefore it is set here as
|
|
chart dispatch.</p>
