java.lang.Object

org.wikidata.query.rdf.blazegraph.inline.literal.AbstractMultiTypeExtension<V>

Type Parameters:

V - Blazegraph value to expand. These are usually treated a bit roughly by Blazegraph - lots of rawtypes

Constructor Detail

AbstractMultiTypeExtension

public AbstractMultiTypeExtension(com.bigdata.rdf.internal.IDatatypeURIResolver resolver,
                                  List<org.openrdf.model.URI> supportedDataTypes)

Method Detail

getDatatypes

public Set<com.bigdata.rdf.model.BigdataURI> getDatatypes()

Specified by:

getDatatypes in interface com.bigdata.rdf.internal.IExtension<V extends com.bigdata.rdf.model.BigdataValue>

createIV

public com.bigdata.rdf.internal.impl.literal.LiteralExtensionIV createIV(org.openrdf.model.Value value)

Specified by:

createIV in interface com.bigdata.rdf.internal.IExtension<V extends com.bigdata.rdf.model.BigdataValue>

asValue

public V asValue(com.bigdata.rdf.internal.impl.literal.LiteralExtensionIV iv,
                 com.bigdata.rdf.model.BigdataValueFactory vf)

Specified by:

asValue in interface com.bigdata.rdf.internal.IExtension<V extends com.bigdata.rdf.model.BigdataValue>

createDelegateIV

protected abstract com.bigdata.rdf.internal.impl.literal.AbstractLiteralIV createDelegateIV(org.openrdf.model.Literal literal,
                                                                                            com.bigdata.rdf.model.BigdataURI dt)

Create the delegate iv for the literal.

safeAsValue

protected abstract com.bigdata.rdf.model.BigdataLiteral safeAsValue(com.bigdata.rdf.internal.impl.literal.LiteralExtensionIV iv,
                                                                    com.bigdata.rdf.model.BigdataValueFactory vf,
                                                                    com.bigdata.rdf.model.BigdataURI dt)

Convert the iv into the value. Its ok to throw exceptions here and the caller will catch them an make them ok with Blazegraph, thus "safe".

resolveDataType

protected com.bigdata.rdf.model.BigdataURI resolveDataType(com.bigdata.rdf.internal.impl.literal.LiteralExtensionIV literal)

Convert the literal into a uri as resolved by the resolve this extension received on construction.

resolveDataType

protected com.bigdata.rdf.model.BigdataURI resolveDataType(org.openrdf.model.Literal literal)

Resolve the data type uri from the literal's type.
