Constructor Summary

Range(Comparable<T> lowerBound, Comparable<T> upperBound)
both bounds are considered inclusive within the range.

Range(Comparable<T> lowerBound, Comparable<T> upperBound, boolean inclusive)
if either or both (lower- and upperBound) are non-null, they represent a limit that is either inclusive or not depending on the given boolean.

Method Summary

Comparable<T>	getLowerBound()
Comparable<T>	getUpperBound()
boolean	isInclusive()
boolean	isInRange(T obj)

Constructor Detail

Range

public Range(Comparable<T> lowerBound,
             Comparable<T> upperBound)

both bounds are considered inclusive within the range.

Range

public Range(Comparable<T> lowerBound,
             Comparable<T> upperBound,
             boolean inclusive)

if either or both (lower- and upperBound) are non-null, they represent a limit that is either inclusive or not depending on the given boolean. Both bounds may not be null (as this doesn't make any sense).
