Type Parameters:

T - the type of range values.

All Implemented Interfaces:

Serializable

@StableMinor(version="12.1",
             sinceVersion="9.0")
public class Range<T extends Comparable<T>>
extends Object
implements Serializable

Represents a range of values by having a from and a to value.

Both from and to may be null, but not at the same time. A null value means an unbounded limit. For example, the range (null, 100) represents all numbers less than or equal to 100, while the range (100, null) represents all numbers greater than or equal to 100.
If both from and to were null at the same time, it would represent the whole universe of possible values.

Since:

9.0.0
