Package com.google.common.collect

Class GeneralRange<T>

java.lang.Object

com.google.common.collect.GeneralRange<T>

All Implemented Interfaces:

java.io.Serializable

final class GeneralRange<T>
extends java.lang.Object
implements java.io.Serializable

A generalized interval on any ordering, for internal use. Supports null. Unlike Range, this allows the use of an arbitrary comparator. This is designed for use in the implementation of subcollections of sorted collection types.

Whenever possible, use Range instead, which is better supported.
