Methods

EncodeForXml(String)

Encodes values for use in XML.

Declaration

public static string EncodeForXml(string value)

Parameters

Type	Name	Description
System.String	value	Value to encode.

Returns

Type	Description
System.String	The value with any ampersands escaped to &.

FindCollections(IGraph, BaseTripleCollection)

Helper method which finds Collections expressed in the Graph which can be compressed into concise collection syntax constructs in some RDF syntaxes.

Declaration

[Obsolete("Use the alternative overloads of this method which take an ICollectionCompressingWriterContext instead", true)]
public static Dictionary<INode, OutputRdfCollection> FindCollections(IGraph g, BaseTripleCollection triplesDone)

Parameters

Type	Name	Description
IGraph	g	Graph to find collections in.
BaseTripleCollection	triplesDone	Triple Collection in which Triples that have been output are to be listed.

Returns

Type	Description
System.Collections.Generic.Dictionary<INode, OutputRdfCollection>

FindCollections(ICollectionCompressingWriterContext)

Helper method which finds Collections expressed in the Graph which can be compressed into concise collection syntax constructs in some RDF syntaxes.

Declaration

public static void FindCollections(ICollectionCompressingWriterContext context)

Parameters

Type	Name	Description
ICollectionCompressingWriterContext	context	Writer Context.

FindCollections(ICollectionCompressingWriterContext, CollectionSearchMode)

Helper method which finds Collections expressed in the Graph which can be compressed into concise collection syntax constructs in some RDF syntaxes.

Declaration

public static void FindCollections(ICollectionCompressingWriterContext context, CollectionSearchMode mode)

Parameters

Type	Name	Description
ICollectionCompressingWriterContext	context	Writer Context.
CollectionSearchMode	mode	Collection Search Mode.

GetTriplesSortedBySubjectPredicate(IGraph)

Get a list of all triples in the specified graph, sorted by subject and then predicate.

Declaration

public static List<Triple> GetTriplesSortedBySubjectPredicate(IGraph graph)

Parameters

Type	Name	Description
IGraph	graph	The graph whose triples are to be returned.

Returns

Type	Description
System.Collections.Generic.List<Triple>	A list of the triples in graph sorted by their subject and then predicate.

IsDefaultGraph(Uri)

Determines whether a given Uri refers to one of the Default Graph URIs assigned to the default Graph when parsing from some RDF dataset syntax.

Declaration

[Obsolete("No longer required since all code that uses 'magic' URIs to refer to the default graph has been removed from the API", true)]
public static bool IsDefaultGraph(Uri u)

Parameters

Type	Name	Description
System.Uri	u	Uri to test.

Returns

Type	Description
System.Boolean

IsValidBlankNodeID(String)

Determines whether a Blank Node ID is valid as-is when serialised in NTriple like syntaxes (Turtle/N3/SPARQL).

Declaration

public static bool IsValidBlankNodeID(string id)

Parameters

Type	Name	Description
System.String	id	ID to test.

Returns

Type	Description
System.Boolean

Remarks

If false is returned then the writer will alter the ID in some way.

IsValidStrictBlankNodeID(String)

Determines whether a Blank Node ID is valid as-is when serialised as NTriples.

Declaration

public static bool IsValidStrictBlankNodeID(string id)

Parameters

Type	Name	Description
System.String	id

Returns

Type	Description
System.Boolean

SortTriplesBySubjectPredicate(List<Triple>)

Sort the provided list of triples by subject and then predicate. The list is modified in-place.

Declaration

public static void SortTriplesBySubjectPredicate(List<Triple> ts)

Parameters

Type	Name	Description
System.Collections.Generic.List<Triple>	ts	The list of triples to be sorted.
