Method Detail

value

public T1 value(T2 first)

Description copied from interface: FunctionalRelation

Produce the second corresponding to first, or null if there is none.

Specified by:

value in interface FunctionalRelation<T2,T1>

Specified by:

value in interface Lambda<T2,T1>

functionMap

public LambdaMap<T2,T1> functionMap()

Description copied from interface: FunctionalRelation

A map view of the relation, mapping firsts to seconds. Need not allow mutation, but must reflect subsequent changes.

Specified by:

functionMap in interface FunctionalRelation<T2,T1>

inverse

public Relation<T1,T2> inverse()

Description copied from interface: Relation

Produce the inverse of the relation, derived by swapping the elements of each pair. Need not allow mutation, but must reflect subsequent changes.

Specified by:

inverse in interface FunctionalRelation<T2,T1>

Specified by:

inverse in interface Relation<T2,T1>

Overrides:

inverse in class AbstractRelation.InverseRelation
