Method Summary

Modifier and Type	Method	Description
Map<IRI,Set<IRI>>	buildOneToMany()	Builds a One-to-Many Map using the configuration of this builder.
Map<IRI,IRI>	buildOneToOne()	Builds a One-to-One Map using the configuration of this builder.
RelationMapBuilder	constraints(GraphPattern... constraints)	Constrains the result iff the GraphPattern contains the variables _relSubject and/or _relObject, which are the variables in the triple with the RdfPredicate specified in the constructor.
RelationMapBuilder	relationIsOptional()	Indicates that the existence of the triple is not required, allowing to use the constraints to select certain subjects and to answer the mapping to an empty Set in the buildOneToMany() case and NOTHING in the buildOneToOne() case.
RelationMapBuilder	useRelationObjectAsKey()	Indicates that the builder should use the triple's object for the key in the resulting Map instead of the subject (the default).

 RdfPredicate predicate)

RelationMapBuilder

public RelationMapBuilder(RDF4JTemplate rdf4JTemplate,
 IRI predicate)

Method Details

constraints

public RelationMapBuilder constraints(GraphPattern... constraints)

Constrains the result iff the GraphPattern contains the variables _relSubject and/or _relObject, which are the variables in the triple with the RdfPredicate specified in the constructor.

relationIsOptional

public RelationMapBuilder relationIsOptional()

Indicates that the existence of the triple is not required, allowing to use the constraints to select certain subjects and to answer the mapping to an empty Set in the buildOneToMany() case and NOTHING in the buildOneToOne() case.

Returns:

the builder

useRelationObjectAsKey

public RelationMapBuilder useRelationObjectAsKey()

Indicates that the builder should use the triple's object for the key in the resulting Map instead of the subject (the default).

buildOneToOne

public Map<IRI,IRI> buildOneToOne()

Builds a One-to-One Map using the configuration of this builder. Throws an Exception if more than one values are found for a given key. If isRelationOptional is true and no triple is found for the key, NOTHING is set as the value.

buildOneToMany

public Map<IRI,Set<IRI>> buildOneToMany()

Builds a One-to-Many Map using the configuration of this builder.
