Partitions the given List of values into another List, in which all of the values from the given list exist in the new list, and all values that compare equal are adjacent to each other, according to the given Extractor.

Specified by:

discriminate in interface Discriminator<java.lang.Character>

Overrides:

discriminate in class PortionDiscriminator<java.lang.Character>

Type Parameters:

E - The type of element that is being discriminated by the type <E>

Parameters:

elements - A List of elements.

extractor - An Extractor that gives labels for each element.
