Class FilterSet

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

All Implemented Interfaces:

Collection, Serializable, Set

public class FilterSet

extends Object

implements Set, Serializable

The FilterSet class contains another Set, 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 set is serializable.
