\class SignalCacheModel signalcachemodel.h Soprano/Util/SignalCacheModel
Caches multiple signals into one to avoid slowdown when adding
or removing many statements.
When adding or removing many statements with separate calls to Model.addStatement
or Model.removeStatement Model emits signals Model.statementsAdded and Model.statementsRemoved
over and over for each call. This can slow down an application that monitors
the state of the model.
The SignalCacheModel caches multiple emitted signals into one, trying to ensure
that only one signal is delivered in a certain time. The downside of this is
that signals are not delivered immiadetely but through the event loop. This,
however, should seldomly be a problem.
