All Implemented Interfaces:: ByteRange, PositionedByteRange, Comparable<ByteRange>

public class SimplePositionedMutableByteRange extends AbstractPositionedByteRange

Extends the basic AbstractPositionedByteRange implementation with position support and it is a mutable version. position is considered transient, not fundamental to the definition of the range, and does not participate in AbstractByteRange.compareTo(ByteRange), AbstractByteRange.hashCode(), or Object.equals(Object). Position is retained by copy operations.
