Class Range

java.lang.Object
  jal.bytes.Range

public final class Range

extends Object

A range of values within an array, consisting of the array, the index of the first element in the range, and an index one past the range. The notation is [first, last), indicating that array[first] is part of the range but array[last] is not. The range [n, n) is a valid range that contains zero elements, while the range [n, n-1) is invalid.

Note that operations on a Range object do not actually change any array elements. A Range is simply a way of describing a set of values.
