true if the graph contains triples, otherwise false

Since:

3.5

addTriple

public void addTriple(RDFTriple triple)

Parameters:

triple - triple to add

getTriplesForSubject

@Deprecated
public Set<RDFTriple> getTriplesForSubject(RDFNode subject)

Deprecated. this method makes a defensive copy for each element in the map, but most uses of this only iterate over the results. Use getSortedTriplesForResult instead

Parameters:

subject - node to search

Returns:

triples which have subject as subject

getSortedTriplesForSubject

public List<RDFTriple> getSortedTriplesForSubject(RDFNode subject,
                                         boolean sort)

isAnonymousNodeSharedSubject

public boolean isAnonymousNodeSharedSubject(RDFResourceNode node)

Parameters:

node - node to search

Returns:

true if the anon node is shared

getRootAnonymousNodes

public Set<RDFResourceNode> getRootAnonymousNodes()

Returns:

root anonymous nodes

dumpTriples

public void dumpTriples(Writer w)
                 throws IOException

Parameters:

w - writer to write to

Throws:

IOException - if exceptions happen
