Syntax

public class SparqlUpdateParser : ITraceableTokeniser, IObjectParser<SparqlUpdateCommandSet>

Constructors

SparqlUpdateParser()

Creates a new parser instance that parses SPARQL 1.1 syntax and uses the default (root) URI Factory.

Declaration

public SparqlUpdateParser()

SparqlUpdateParser(IUriFactory)

Creates a new parser instance that uses the specified URI factory to create URIs.

Declaration

public SparqlUpdateParser(IUriFactory uriFactory)

Parameters

Type	Name	Description
IUriFactory	uriFactory	The factory to use when creating URIs while parsing the update.

SparqlUpdateParser(SparqlQuerySyntax, IUriFactory)

Creates a new parser instance that uses the specified query syntax and URI factory.

Declaration

public SparqlUpdateParser(SparqlQuerySyntax syntax = SparqlQuerySyntax.Sparql_1_1, IUriFactory uriFactory = null)

Parameters

Type	Name	Description
SparqlQuerySyntax	syntax	The syntax mode to support when parsing the update.
IUriFactory	uriFactory	The factory to use when creating URIs while parsing the update.

Properties

AllowUnknownFunctions

Gets/Sets whether functions that can't be parsed into Expressions should be represented by the UnknownFunction.

Declaration

public bool AllowUnknownFunctions { get; set; }

Property Value

Type	Description
bool

DefaultBaseUri

Gets/Sets the Default Base URI used for Updated Commands parsed by this parser instance.

Declaration

public Uri DefaultBaseUri { get; set; }

Property Value

Type	Description
Uri

ExpressionFactories

Gets/Sets the locally scoped custom expression factories.

Declaration

public IEnumerable<ISparqlCustomExpressionFactory> ExpressionFactories { get; set; }

Property Value

Type	Description
IEnumerable<ISparqlCustomExpressionFactory>

QueryOptimisation

Get / set whether the update commands should be optimized at the end of the parsing process.

Declaration

public bool QueryOptimisation { get; set; }

Property Value

Type	Description
bool

Remarks

Defaults to true.

QueryOptimiser

Gets/Sets the locally scoped Query Optimiser applied to graph patterns in update commands at the end of the parsing process.

Declaration

public IQueryOptimiser QueryOptimiser { get; set; }

Property Value

Type	Description
IQueryOptimiser

Remarks

May be null if no locally scoped optimiser is set in which case the globally scoped optimiser will be used.
