All Implemented Interfaces:

IExtension<V>

public class DerivedNumericsExtension<V extends BigdataValue>
extends Object
implements IExtension<V>

This implementation of IExtension implements inlining for literals that represent the derived numeric types:

• xsd:nonPositiveInteger
• xsd:negativeInteger
• xsd:nonNegativeInteger
• xsd:positiveInteger

Methods

Modifier and Type	Method and Description
V	asValue(LiteralExtensionIV iv, BigdataValueFactory vf) Use the BigInteger value of the XSDIntegerIV delegate to create a datatype literal value with the appropriate datatype.
LiteralExtensionIV	createIV(org.openrdf.model.Value value) Attempts to convert the supplied value into an internal representation using BigInteger.
Set<BigdataURI>	getDatatypes() Return the fully resolved datatype(s) handled by this interface in the form of a BigdataURI with the TermId already set.

Method Detail

getDatatypes

public Set<BigdataURI> getDatatypes()

Description copied from interface: IExtension

Return the fully resolved datatype(s) handled by this interface in the form of a BigdataURI with the TermId already set.

Specified by:

getDatatypes in interface IExtension<V extends BigdataValue>

Returns:

the datatype

createIV

public LiteralExtensionIV createIV(org.openrdf.model.Value value)

Attempts to convert the supplied value into an internal representation using BigInteger.

Specified by:

createIV in interface IExtension<V extends BigdataValue>

Parameters:

value - The RDF Value

Returns:

The extension IV -or- null if the Value can not be inlined using this IExtension.

asValue

public V asValue(LiteralExtensionIV iv,
        BigdataValueFactory vf)

Use the BigInteger value of the XSDIntegerIV delegate to create a datatype literal value with the appropriate datatype.

Specified by:

asValue in interface IExtension<V extends BigdataValue>

Parameters:

iv - The extension IV

vf - The bigdata value factory

Returns:

The RDF Value
