Class FilterSortedSet

java.lang.Object
  |
  +--gausssoft.collections.FilterSortedSet

All Implemented Interfaces:

Collection, Set, SortedSet

public class FilterSortedSet

extends Object

implements SortedSet

The FilterSortedSet class contains another SortedSet, which it uses as it's basic source of data, possibly transforming the data along the way or providing additional functionality.

Each method in this implementation calls the method with the same signature in the backing set.

This class can only be serialized if the backing sorted set is serializable.
