Syntax

public class ThreadSafeTripleCollection : WrapperTripleCollection, IEnumerable<Triple>, IEnumerable, IDisposable

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.

Constructors

ThreadSafeTripleCollection()

Creates a new thread safe triple collection which wraps a new instance of the default unindexed TripleCollection.

Declaration

public ThreadSafeTripleCollection()

ThreadSafeTripleCollection(BaseTripleCollection)

Creates a new thread safe triple collection which wraps the provided triple collection.

Declaration

public ThreadSafeTripleCollection(BaseTripleCollection tripleCollection)
