Method Detail

add

public boolean add(FixedPair<FROM,TO> a)

Description copied from interface: UniMultiRelationship

Adds a pair to the relationship.

Specified by:

add in interface UniMultiRelationship<FROM,TO,FixedPair<FROM,TO>>

get

public FixedPair<FROM,TO> get(FROM f,
                              TO t)

Description copied from interface: UniMultiRelationship

Gets a Pair instance.

Specified by:

get in interface UniMultiRelationship<FROM,TO,FixedPair<FROM,TO>>

add

public boolean add(FROM f,
                   TO t)

Specified by:

add in interface SimpleRelationship<FROM,TO>

clearFrom

public void clearFrom(FROM f)

Description copied from interface: UniMultiRelationship

Clears all pairs with t in the TO position

Specified by:

clearFrom in interface UniMultiRelationship<FROM,TO,FixedPair<FROM,TO>>

clearTo

public void clearTo(TO t)

Description copied from interface: MultiRelationship

Clears all pairs with t in the TO position

Specified by:
