Methods

	Name	Description
	Add	Adds a Triple to the Collection. (Overrides WrapperTripleCollection.Add(Triple).)
	Contains	Determines whether a given Triple is in the Triple Collection. (Overrides WrapperTripleCollection.Contains(Triple).)

Events

	Name	Description
	TripleAdded	Event which occurs when a Triple is added to the Collection (Inherited from BaseTripleCollection.)

Remarks

Depending on the platform this either uses ReaderWriterLockSlim to provide MRSW concurrency or it uses Monitor to provide exclusive access concurrency, either way usage is thread safe.

Thread Safety

This decorator provides thread safe access to any underlying triple collection.
