@InterfaceAudience.Private @InterfaceStability.Evolving public abstract class AbstractPositionedByteRange extends AbstractByteRange implements PositionedByteRange
SimpleByteRange implementation with position
support. 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.| Modifier and Type | Field and Description |

ByteBuffer position, it
points to the next value that will be read/written in the array. It
provides the appearance of being 0-indexed, even though its value is
calculated according to offset.
Position is considered transient and does not participate in
Object.equals(Object) or AbstractByteRange.hashCode() comparisons.
