Syntax

public class ThreadSafeGraph : Graph, IGraph, INodeFactory, IDisposable, ITripleIndex, IEquatable<IGraph>, IEquatable<Graph>, IEquatable<ThreadSafeGraph>

Remarks

Performance will be marginally worse than a normal Graph but in multi-threaded scenarios this will likely be offset by the benefits of multi-threading.

Constructors

ThreadSafeGraph()

Creates a new Thread Safe Graph.

Declaration

public ThreadSafeGraph()

ThreadSafeGraph(BaseTripleCollection)

Creates a new Thread Safe graph using the given Triple Collection.

Declaration

public ThreadSafeGraph(BaseTripleCollection tripleCollection)

Parameters

Type	Name	Description
IRefNode	name	The graph name.

ThreadSafeGraph(IRefNode, BaseTripleCollection)

Creates a new named thread-safe graph using the given triple collection.

Declaration

public ThreadSafeGraph(IRefNode name, BaseTripleCollection tripleCollection)

Parameters

Type	Name	Description
IRefNode	name	The graph name.
