Enum QueryEvaluationMode

java.lang.Object

java.lang.Enum<QueryEvaluationMode>

org.eclipse.rdf4j.common.transaction.QueryEvaluationMode

All Implemented Interfaces:

Serializable, Comparable<QueryEvaluationMode>, TransactionSetting

public enum QueryEvaluationMode
extends Enum<QueryEvaluationMode>
implements TransactionSetting

The Query Evaluation Mode determines the behaviour of the SPARQL query engine on RDF4J repositories. It currently supports two modes, STRICT and and STANDARD.

Enum Constant Summary

Enum Constants

Enum Constant	Description
STANDARD	Standard mode extends minimal compliance with various practical operator behavioral extensions, in a way that is still compliant with the SPARQL 1.1 specification (as described in section 17.3.1 of the SPARQL 1.1 Query Recommendation).
STRICT	Strict minimally-compliant mode for SPARQL 1.1.

Method Summary

Modifier and Type	Method	Description
static QueryEvaluationMode	valueOf(String name)	Returns the enum constant of this type with the specified name.
static QueryEvaluationMode[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Details

STRICT

public static final QueryEvaluationMode STRICT

Strict minimally-compliant mode for SPARQL 1.1. In this mode, no operators have been extended (as described in section 17.3.1 of the SPARQL 1.1 Query Recommendation).

STANDARD

public static final QueryEvaluationMode STANDARD

Standard mode extends minimal compliance with various practical operator behavioral extensions, in a way that is still compliant with the SPARQL 1.1 specification (as described in section 17.3.1 of the SPARQL 1.1 Query Recommendation).

Method Details

values

public static QueryEvaluationMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared.

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static QueryEvaluationMode valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
