public CorruptUnknownValue(ValueStoreRevision revision,
 int internalID,
 byte[] data)

Method Details

getLabel

public String getLabel()

Description copied from interface: Literal

Gets the label (the lexical value) of this literal.

Specified by:

getLabel in interface Literal

Returns:

The literal's label.

getLanguage

public Optional<String> getLanguage()

Description copied from interface: Literal

Gets the language tag for this literal, normalized to lower case.

Specified by:

getLanguage in interface Literal

Returns:

The language tag for this literal, or Optional.empty() if it doesn't have one.

getDatatype

public IRI getDatatype()

Description copied from interface: Literal

Gets the datatype for this literal.

If Literal.getLanguage() returns a non-empty value than this must return rdf:langString. If no datatype was assigned to this literal by the creator, then this method must return xsd:string.

Specified by:

getDatatype in interface Literal

Returns:

The datatype for this literal.

booleanValue

public boolean booleanValue()

Description copied from interface: Literal

Returns the boolean value of this literal.

Specified by:

booleanValue in interface Literal

Returns:

The boolean value of the literal.

byteValue

public byte byteValue()

Description copied from interface: Literal

Returns the byte value of this literal.

Specified by:

byteValue in interface Literal

Returns:

The byte value of the literal.

shortValue

public short shortValue()

Description copied from interface: Literal

Returns the short value of this literal.

Specified by:

shortValue in interface Literal

Returns:

The short value of the literal.

intValue

public int intValue()

Description copied from interface: Literal

Returns the int value of this literal.

Specified by:

intValue in interface Literal

Returns:

The int value of the literal.

longValue

public long longValue()

Description copied from interface: Literal

Returns the long value of this literal.

Specified by:

longValue in interface Literal

Returns:

The long value of the literal.

integerValue

public BigInteger integerValue()

Description copied from interface: Literal

Returns the integer value of this literal.

Specified by:

integerValue in interface Literal

Returns:

The integer value of the literal.

decimalValue

public BigDecimal decimalValue()

Description copied from interface: Literal

Returns the decimal value of this literal.

Specified by:

decimalValue in interface Literal

Returns:

The decimal value of the literal.

floatValue

public float floatValue()

Description copied from interface: Literal

Returns the float value of this literal.

Specified by:

floatValue in interface Literal

Returns:

The float value of the literal.

doubleValue

public double doubleValue()

Description copied from interface: Literal

Returns the double value of this literal.

Specified by:

doubleValue in interface Literal

Returns:

The double value of the literal.

calendarValue

public XMLGregorianCalendar calendarValue()

Description copied from interface: Literal

Returns the XMLGregorianCalendar value of this literal. A calendar representation can be given for literals whose label conforms to the syntax of the following XML Schema datatypes: dateTime, time, date, gYearMonth, gMonthDay, gYear, gMonth or gDay.

Specified by:

calendarValue in interface Literal

Returns:

The calendar value of the literal.

getCoreDatatype

public CoreDatatype 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

Returns:

The CoreDatatype or

invalid @link

{@link CoreDatatype#NONE)

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

equals

public boolean equals(Object o)

Description copied from interface: Literal

Compares this literal to another object.

Specified by:

equals in interface Literal

Overrides:

equals in class CorruptValue

Parameters:

o - the object to compare this literal to

Returns:

true, if the other object is an instance of Literal and if their labels, language tags and datatypes are equal
