Constructor Detail

NodeToTriplesMap

public NodeToTriplesMap(Triple.Field indexField,
                        Triple.Field f2,
                        Triple.Field f3)

Method Detail

add

public boolean add(Triple t)

Description copied from class: NodeToTriplesMapBase

Add t to this NTM; the node o must be the index node of the triple. Answer true iff the triple was not previously in the set, ie, it really truly has been added.

Specified by:

add in class NodeToTriplesMapBase

remove

public boolean remove(Triple t)

Description copied from class: NodeToTriplesMapBase

Remove t from this NTM. Answer true iff the triple was previously in the set, ie, it really truly has been removed.

Specified by:

remove in class NodeToTriplesMapBase

iterator

public ExtendedIterator<Triple> iterator(java.lang.Object o,
                                         HashCommon.NotifyEmpty container)

Specified by:

iterator in class NodeToTriplesMapBase

contains

public boolean contains(Triple t)

Description copied from class: NodeToTriplesMapBase

Answer true iff this NTM contains the concrete triple t.

Specified by:

contains in class NodeToTriplesMapBase

containsBySameValueAs

public boolean containsBySameValueAs(Triple t)

Specified by:

containsBySameValueAs in class NodeToTriplesMapBase

iterateAll

public ExtendedIterator<Triple> iterateAll(Triple pattern)

iterator

public ExtendedIterator<Triple> iterator(Node index,
                                         Node n2,
                                         Node n3)

Specified by:

iterator in class NodeToTriplesMapBase

iteratorForIndexed

public java.util.Iterator<Triple> iteratorForIndexed(java.lang.Object y)

Answer an iterator over all the triples that are indexed by the item y. Note that y need not be a Node (because of indexing values).

Specified by:

iteratorForIndexed in class NodeToTriplesMapBase
