Syntax

public class SparqlQueryParserContext : TokenisingParserContext, IParserContext, ITokenisingParserContext

Constructors

SparqlQueryParserContext(SparqlQueryParserContext, ITokenQueue)

Creates a new SPARQL Query Parser Context for parsing sub-queries.

Declaration

protected SparqlQueryParserContext(SparqlQueryParserContext parent, ITokenQueue tokens)

Parameters

Type	Name	Description
SparqlQueryParserContext	parent	Parent Query Parser Context.
ITokenQueue	tokens	Tokens that need parsing to form a subquery.

SparqlQueryParserContext(ITokenQueue, Uri, INamespaceMapper)

Creates a new Query Parser Context from the given Token Queue.

Declaration

protected SparqlQueryParserContext(ITokenQueue tokens, Uri baseUri, INamespaceMapper namespaceMap)

Parameters

Type	Name	Description
ITokenQueue	tokens	Token Queue.
Uri	baseUri	The base URI to use when resolving relative URIS in the query. May be null if there is no initial base URI.
INamespaceMapper	namespaceMap	The namespace map to use when resolving QNames in the query. If null, will default to a new empty namespace map.

SparqlQueryParserContext(ITokeniser)

Creates a new SPARQL Query Parser Context with default settings.

Declaration

public SparqlQueryParserContext(ITokeniser tokeniser)

Parameters

Type	Name	Description
ITokeniser	tokeniser	Tokeniser to use.

SparqlQueryParserContext(ITokeniser, bool, bool)

Creates a new SPARQL Query Parser Context with custom settings.

Declaration

public SparqlQueryParserContext(ITokeniser tokeniser, bool traceParsing, bool traceTokeniser)

Parameters

Type	Name	Description
ITokeniser	tokeniser	Tokeniser to use.
bool	traceParsing	Whether to trace parsing.
bool	traceTokeniser	Whether to trace tokenisation.

SparqlQueryParserContext(ITokeniser, TokenQueueMode)

Creates a new SPARQL Query Parser Context with custom settings.

Declaration

public SparqlQueryParserContext(ITokeniser tokeniser, TokenQueueMode queueMode)

Parameters

Type	Name	Description
ITokeniser	tokeniser	Tokeniser to use.
TokenQueueMode	queueMode	Tokeniser Queue Mode.

SparqlQueryParserContext(ITokeniser, TokenQueueMode, bool, bool, IUriFactory)

Creates a new SPARQL Query Parser Context with custom settings.

Declaration

public SparqlQueryParserContext(ITokeniser tokeniser, TokenQueueMode queueMode, bool traceParsing, bool traceTokeniser, IUriFactory uriFactory = null)

Parameters

Type	Name	Description
ITokeniser	tokeniser	Tokeniser to use.
TokenQueueMode	queueMode	Tokeniser Queue Mode.
bool	traceParsing	Whether to trace parsing.
bool	traceTokeniser	Whether to trace tokenisation.
IUriFactory	uriFactory	URI Factory to use.

Properties
