org.apache.hadoop.hbase.types.OrderedBlobVar
@InterfaceAudience.Private @InterfaceStability.Evolving public class OrderedBlobVar
An alternative to OrderedBlob for use by Struct fields that
do not terminate the fields list. Built on

public int encodedLength(byte[] val)
DataTypebyte[] will be.
val - The value to check.
val.apublic Class<byte[]> encodedClass()
DataTypeDataType operates. Useful
when working with bare DataType instances.
public byte[] decode(PositionedByteRange src)
DataTypeT from the buffer src.
src - the buffer containing the encoded value.
public int encode(PositionedByteRange dst,
byte[] val)
DataTypeval into buffer dst.
dst - the buffer containing the encoded value.val - the value to encode onto dst.
public int encode(PositionedByteRange dst,
byte[] val,
int voff,
int vlen)
val to buff.
