Class FilterList

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

All Implemented Interfaces:

Collection, List, Serializable

public class FilterList

extends Object

implements List, Serializable

The FilterList class contains another List, 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 list.

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