Class EquivalentHashSet<E>

  • All Implemented Interfaces:
    Iterable<E>, Collection<E>, Set<E>
    public class EquivalentHashSet<E>
extends AbstractSet<E>
    Deprecated.
    Custom hash-based set which accepts no null values, where equality and hash code calculations are done based on passed Equivalence function implementations for values, as opposed to relying on their own equals/hashCode/toString implementations. This is handy when using key/values whose mentioned methods cannot be overriden, i.e. arrays, and in situations where users want to avoid using wrapper objects.
