TripletImpl

public TripletImpl(V subject,
                   E predicate,
                   V object)

Method Detail

makeDirected

public static <V,E> Triplet<V,Directed<E>> makeDirected(Triplet<V,E> in,
                                                                    V source)

makeUndirected

public static <V,E> Triplet<V,E> makeUndirected(Triplet<V,Directed<E>> in)

create

public static <V,E> Triplet<V,E> create(V s,
                                                    E e,
                                                    V o,
                                                    boolean reverse)

getSource

public static <V> V getSource(Triplet<V,?> triplet,
                              boolean reverse)

getTarget

public static <V> V getTarget(Triplet<V,?> triplet,
                              boolean reverse)

getTarget

public static <V> V getTarget(Triplet<V,?> triplet,
                              Object source)

getDirections

public static List<Boolean> getDirections(Triplet<?,?> triplet,
                                          Object node)

Return a list of indices based on whether the given node is equal to the triple's subject and/or object.

Parameters:

triplet -

node -

Returns:

getDirection

public static int getDirection(Triplet<?,?> triplet,
                               Object node)

Returns a bit mask: index: 1 0 [bwdBit] [fwdBit] The first bit indicates whether the subject was equal to the given node, the second bit whether the object was equal to the given node. Possible values are therefore 0 (no match), 3 (both subject and object matched) or 1 and 2.

Parameters:

triplet -

node -

Returns:

getSubject

public V getSubject()

Specified by:

getSubject in interface Triplet<V,E>

getPredicate

public E getPredicate()

Specified by:

getPredicate in interface Triplet<V,E>

getObject

public V getObject()

Specified by:

getObject in interface Triplet<V,E>

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object
