Method Detail

find

java.util.Iterator<Triple> find(Node s,
                                Node p,
                                Node o)

Return an iterator over all triples matching the (s,p,o) pattern. Each element of (s,p,o) can be concrete, or the wildcard Node.ANY.

contains

boolean contains(Node s,
                 Node p,
                 Node o)

Return whether any triple matches the (s,p,o) pattern. Each element of (s,p,o) can be concrete, or the wildcard Node.ANY.

count

default int count(Node s,
                  Node p,
                  Node o)

Return the number of triples matching the (s,p,o) pattern.
