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.

PlainMultiThreading |
In PlainMultiThreading mode only one action can be performed at the same time. Calls block until the previous call is done.
|
ReadWriteMultiThreading |
In ReadWriteMultiThreading mode multiple read operations can be performed at the same time but only one write operation. In general write operations take precedence over read operations when locking. However, the same thread can perform nested read locks an arbitrary number of times. |
ReadWriteSingleThreading |
