searchForObject

public <T> T searchForObject(Identifier subject,
                             IRI predicate,
                             Class<T> assignableTo)

Retrieve the first object by specified subject and predicates, which is assignable to a specified class. If an argument is null then it will match all values.

Parameters:

subject - to filter or null for wildcard.

predicate - to filter or null for wildcard.

assignableTo - verify if the result may be casted to the specified type

Returns:

The first object of a triple to match the subject and predicate.

searchForObjectByJoin

public Identifier searchForObjectByJoin(Identifier subject,
                                        IRI predicate,
                                        IRI predicate2,
                                        Identifier object)

Retrieve the first ?result to bind the pattern . This is regarded as a primitive join operation between triples.

Parameters:

subject - the value of ?s, may be null for wildcard.

predicate - the value of ?p1, may be null for wildcard.

predicate2 - the value of ?p2, may be null for wildcard.

object - the value of ?o, may be null for wildcard.

Returns:

the value of ?return or null if no match is possible
