public abstract class AbstractLongSet
An abstract implementation of Set to make it easier to create your own implementations. In order to create a Set, subclass AbstractSet and implement the same methods that are required for AbstractCollection (although these methods must of course meet the requirements that Set puts on them - specifically, no element may be in the set more than once). This class simply provides implementations of equals() and hashCode() to fulfil the requirements placed on them by the Set interface.

size()
to determine
the smaller collection. Then, if this set is smaller, it iterates
over the set, calling Iterator.remove if the collection contains
the element. If this set is larger, it iterates over the collection,
calling Set.remove for all elements in the collection. Note that
this operation will fail if a remove methods is not supported.
