Method Detail

andHas

default TriplePattern andHas(RdfPredicate predicate,
                             RdfObject... objects)

Add predicate-object lists describing this triple pattern's subject

Parameters:

predicate - the predicate to use to describe this triple pattern's subject

objects - the corresponding object(s)

Returns:

this triple pattern

andHas

TriplePattern andHas(RdfPredicateObjectList... lists)

Add predicate-object lists describing this triple pattern's subject

Parameters:

lists - the RdfPredicateObjectList(s) to add

Returns:

this triple pattern

andHas

default TriplePattern andHas(RdfPredicate predicate,
                             String... objects)

Convenience version of andHas(RdfPredicate, RdfObject...) that takes Strings and converts them to StringLiterals

Parameters:

predicate - the predicate to use to describe this triple pattern's subject

objects - the corresponding object(s)

Returns:

this triple pattern

andHas

default TriplePattern andHas(RdfPredicate predicate,
                             Boolean... objects)

Convenience version of andHas(RdfPredicate, RdfObject...) that takes Boolean and converts them to BooleanLiterals

Parameters:

predicate - the predicate to use to describe this triple pattern's subject

objects - the corresponding object(s)

Returns:

this triple pattern

andHas

default TriplePattern andHas(RdfPredicate predicate,
                             Number... objects)

Convenience version of andHas(RdfPredicate, RdfObject...) that takes Numbers and converts them to NumberLiterals

Parameters:

predicate - the predicate to use to describe this triple pattern's subject

objects - the corresponding object(s)

Returns:

this triple pattern

andIsA

default TriplePattern andIsA(RdfObject object)

Use the built-in RDF shortcut a for rdf:type to specify the subject's type

Parameters:

object - the object describing this triple pattern's subject's rdf:type

Returns:

this triple pattern

RDF Type abbreviation

isEmpty

default boolean isEmpty()

Specified by:

isEmpty in interface GraphPattern

Returns:

if this pattern is a collection of GraphPatterns (ie., Group or Alternative patterns), returns if the collection contains any patterns
