Method Details

getCoreXsdDatatype

protected CoreDatatype.XSD getCoreXsdDatatype()

Specified by:

getCoreXsdDatatype in class CastFunction

isValidForDatatype

protected boolean isValidForDatatype(String lexicalValue)

Description copied from class: CastFunction

Verifies that the supplied lexical value is valid for the datatype.

Specified by:

isValidForDatatype in class CastFunction

Parameters:

lexicalValue - a lexical value

Returns:

true if the lexical value is valid for the datatype, false otherwise.

createTypedLiteral

protected Optional<Literal> createTypedLiteral(ValueFactory vf,
 BigInteger integerValue)
                                        throws ArithmeticException

Description copied from class: IntegerCastFunction

create a Literal with the specific datatype for the supplied BigInteger value.

Specified by:

createTypedLiteral in class IntegerCastFunction

Parameters:

vf - the ValueFactory to use for creating the Literal

integerValue - the integer value to use for creating the Literal

Returns:

an Optional literal value, which may be empty if the supplied integerValue can not be successfully converted to the specific datatype.

Throws:

ArithmeticException - if an error occurs when attempting to convert the supplied value to a value of the specific datatype.
