Field Details

TRUE

public static final BooleanLiteral TRUE

FALSE

public static final BooleanLiteral FALSE

Constructor Details

BooleanLiteral

protected BooleanLiteral(boolean value)

Creates an xsd:boolean typed literal with the specified value.

Method Details

booleanValue

public boolean booleanValue()

Description copied from interface: Literal

Returns the boolean value of this literal.

Specified by:

booleanValue in interface Literal

Overrides:

booleanValue in class SimpleLiteral

Returns:

The boolean value of the literal.

valueOf

public static BooleanLiteral valueOf(boolean value)

Returns a BooleanLiteral for the specified value. This method uses the constants TRUE and FALSE as result values, preventing the often unnecessary creation of new BooleanLiteral objects.

getCoreDatatype

public CoreDatatype.XSD getCoreDatatype()

Description copied from interface: Literal

CoreDatatype is an interface for natively supported datatypes in RDF4J. This includes, among others, the XML Schema datatypes and rdf:langString. CoreDatatypes are implemented as enums and more performant and convenient to work with than IRI-based datatypes. The constant

invalid @link

{@link CoreDatatype#NONE)

} is used to represent a datatype that is not one of the supported core datatypes.

Specified by:

getCoreDatatype in interface Literal

Overrides:

getCoreDatatype in class SimpleLiteral

Returns:

The CoreDatatype or

invalid @link

{@link CoreDatatype#NONE)

} if the datatype matches none of the core datatypes. This method will not return null.
