All Implemented Interfaces:

Discriminator<java.util.List<T>>

public class RandomAccessListDiscriminator<T>
extends ChainedDiscriminator<java.util.List<T>>

A RandomAccessListDiscriminator discriminates Lists of Lists. The Lists are the items being discriminated and they should implement RandomAccess.
