Constructor Details

UnionSetView

public UnionSetView(Set<? extends E> set1,
 Set<? extends E> set2)

Expects the two sets to be disjoint, otherwise some methods, e.g. size(), will return unreasonable results.

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

Parameters:

set1 - the first set

set2 - the second set
