@InterfaceAudience.Public public class SimplePositionedByteRange extends AbstractPositionedByteRange
SimpleMutableByteRange implementation with position
support and it is a readonly version. position is considered
transient, not fundamental to the definition of the range, and does not
participate in AbstractByteRange.compareTo(ByteRange), AbstractByteRange.hashCode(), or
AbstractByteRange.equals(Object). Position is retained by copy operations.limit, positionbytes, hash, length, offset, UNSET_HASH_VALUE| Constructor and Description |
