Constructor Details

MinusSetView

public MinusSetView(Set<E> superset,
 Set<E> subset)

Constructs a view of the result of superset - subset.

As the name suggests, it is expected that all elements of subset are contained in superset, otherwise one has to expect unreasonable results.

It is up to the caller to ensure this property, this class performs no additional checks.

Parameters:

superset - the minuend

subset - the subtrahend
