<dd class='body--doc'><p>This class implements a quantized resource scheduler.</p>
<p> Weighted consumers are added to the scheduler with <a class='ms reference' href='../../predef_3A_3A/ADT/Scheduler/add.html'>add()</a>,
which returns a <a class='ms reference' href='../../predef_3A_3A/ADT/Scheduler/Consumer.html'>Consumer</a> object.</p>
<p> When there's some of the resource available to be consumed
the resource owner calls <a class='ms reference' href='../../predef_3A_3A/ADT/Scheduler/get.html'>get()</a>, which returns the
<a class='ms reference' href='../../predef_3A_3A/ADT/Scheduler/Consumer.html'>Consumer</a> that is to use the resource. <a class='ms reference' href='../../predef_3A_3A/ADT/Scheduler/Consumer/consume.html'>Consumer()->consume()</a>
is then called with the fraction of the quanta that was consumed
(typically <code class='expr'>1.0</code>). The amount of resources allocated to a
consumer is proportional to the weight of the consumer.</p>
<p> A consumer may be temporarily deactivated (in which case it won't
be returned by <a class='ms reference' href='../../predef_3A_3A/ADT/Scheduler/get.html'>get()</a>, but still retain its share of the resource
which will be provided later by <a class='ms reference' href='../../predef_3A_3A/ADT/Scheduler/get.html'>get()</a> when it has been reactivated.</p>
