Declaration

public static void FindAnnotations(IAnnotationCompressingWriterContext context)

Parameters

Type	Name	Description
IAnnotationCompressingWriterContext	context	Writer context.

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

IGraph	graph	The graph whose triples are to be returned.

Returns

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

IsValidBlankNodeID(string)

Declaration

public static bool IsValidBlankNodeID(string id)

Parameters

Type	Name	Description
string	id	ID to test.

Returns

Type	Description
bool

Remarks

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

IsValidStrictBlankNodeID(string)

Declaration

public static void SortTriplesBySubjectPredicate(List<Triple> ts)

Parameters

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