MutexModel Class Reference
from PyKDE4.soprano import *
Inherits: Soprano.FilterModel → Soprano.Model → QObject
Namespace: Soprano.Util
Detailed Description
\class MutexModel mutexmodel.h Soprano/Util/MutexModel
Protect a Model for multiple calls in multi-threaded
applications.
In most cases one does not need to use this FilterModel since Models
created by Soprano.createModel and Soprano.Backend.createModel
are thread-safe. It may, however, come in handy for custom models.
