Constructor Detail

TransSet

public TransSet(Set<S> source,
                Function<S,T> sourceToTarget,
                Function<T,S> targetToSource)

Creates a new TransSet with the specified source Set, and functions defining the translation of objects types S -> T and T -> S.

If sourceToTarget is null, all methods that require a translation of S -> T will throw a UnsupportedOperationException.

If targetToSource is null, all methods that require a translation of T -> S will throw a UnsupportedOperationException.

Parameters:

source - The source Set of type <S>.

sourceToTarget - The Function defining the translation from S -> T.

targetToSource - The Function defining the translation from T -> S.

Throws:

NullPointerException - If source is null.
