All Implemented Interfaces:

Collection, Serializable, Set

public class AltFilterSet

extends AbstractSet

implements Serializable

The AltFilterSet wraps around another Set object providing the same functionality as AbstractSet.

See the AltFilterCollection class for a description why the AltFilter classes exist.

This object is only serializable if the backing set is serializable. All methods which override the subclass implementations simply call the method of the same name in the backing set.
