evaluate
@Deprecated Value evaluate(ValueFactory valueFactory, Value... args) throws ValueExprEvaluationException
Deprecated.since 3.3.0. Useevaluate(TripleSource, Value...)instead. A reference to a ValueFactory can be retrieved usingTripleSource.getValueFactory()if needed.Evaluate the function over the supplied input arguments, using the suppliedValueFactoryto produce the result.- Parameters:
valueFactory- aValueFactoryto use for producing the function result.args- the function input arguments.- Returns:
- the function result value.
- Throws:
ValueExprEvaluationException

evaluate
default Value evaluate(TripleSource tripleSource, Value... args) throws ValueExprEvaluationException
Evaluate the function over the supplied input arguments.- Parameters:
tripleSource- theTripleSourceused in the query evaluation. This can be used to access the current state of the store.args- the function input arguments.- Returns:
- the function result value.
- Throws:
ValueExprEvaluationException- Since:
- 3.3.0
