Syntax

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

Remarks

Caution: All operations on this graph lead to (potentially numerous) network requests. This presents complexity characteristics that are very different from those you might expect from in-memory implementations of the interface.

This graph, like LDF itself, does not support

• blank nodes,
• quoted triples or
• mutation.

Constructors

TpfLiveGraph(Uri, IRdfReader, Loader)

Initializes a new instance of the TpfLiveGraph class.

Declaration

public TpfLiveGraph(Uri baseUri, IRdfReader reader = null, Loader loader = null)

Parameters

Type	Name	Description
Uri	baseUri	The URI of the TPF endpoint used to obtain triples.
IRdfReader	reader	(Optional) The reader to be used for parsing LDF responses (Turtle by default).
Loader	loader	(Optional) The loader to be used when sending LDF requests (Loader by default).

Remarks

When this constructor is called then a network request will be sent to gather the LDF metadata.

Exceptions

Type	Condition
ArgumentNullException	baseUri is null.

Properties

Exceptions

Type	Condition

Property Value

Type	Description
IEnumerable<INode>

Exceptions

Type	Condition

This graph returns no quoted triples because Linked Data Fragments does not support RDF*.

Declaration

public override IEnumerable<Triple> QuotedTriples { get; }

Property Value

Type	Description
IEnumerable<Triple>

Overrides

BaseGraph.QuotedTriples

Exceptions

Type	Condition
LdfException	Throw under various circumstances to represent operations that are illigal in the context of LDF or when this client is not compatible with the response from the LDF endpoint.

This graph cannot assert triples because Linked Data Fragments does not support mutation.

Declaration

public override bool Assert(IEnumerable<Triple> _)

Parameters

Type	Name	Description
IEnumerable<Triple>	_	Ignored.

Returns

Type	Description
bool	Nothing.

Overrides

Graph.Assert(IEnumerable<Triple>)

Exceptions

Type	Condition
NotSupportedException	Always.

Assert(Triple)

This graph cannot assert a triple because Linked Data Fragments does not support mutation.

Declaration

public override bool Assert(Triple _)

Parameters

Type	Name	Description
Triple	_	Ignored.

Returns

Type	Description
bool	Nothing.

Overrides

Graph.Assert(Triple)

Exceptions

Type	Condition
NotSupportedException	Always.

Clear()

This graph cannot be cleared because Linked Data Fragments does not support mutation.

Declaration

public override void Clear()

Overrides

BaseGraph.Clear()

Exceptions

Type	Condition

ContainsQuotedTriple(Triple)

This graph does not contain any quoted triples because Linked Data Fragments does not support RDF*.

Declaration

public override bool ContainsQuotedTriple(Triple _)

Parameters

Type	Name	Description
Triple	_	Ignored.

Returns

Type	Description
bool	False.

Overrides

BaseGraph.ContainsQuotedTriple(Triple)

Exceptions

Type	Condition

Equals(IGraph, out Dictionary<INode, INode>)

Determines whether this graph is equal to the other graph.

Declaration

public override bool Equals(IGraph other, out Dictionary<INode, INode> mapping)

Parameters

Type	Name	Description
IGraph	other	Graph to test for equality.

Returns

Type	Description
bool	Whether this graph is equal to the other graph.

Overrides

BaseGraph.Equals(IGraph, out Dictionary<INode, INode>)

Remarks

LDF graphs are equal to each other if their search templates are the same.

An LDF graph might be equal to other graph types if they contain the same triples.

Caution: Comparing LDF graphs to other types of graphs requires enumerating all statements in the LDF graph, which potentially involves numerous network requests.
