java.lang.Objectorg.apache.hadoop.hbase.types.RawInteger
@InterfaceAudience.Public @InterfaceStability.Evolving public class RawInteger
An DataType
for interacting with values encoded using
Bytes.putInt(byte[], int, int)
. Intended to make it easier to
transition away from direct use of Bytes
.
Bytes.putInt(byte[], int, int)
,
Bytes.toInt(byte[])

public boolean isOrderPreserving()
DataType
byte[]
's
which preserve the natural sort order of the unencoded value.
isOrderPreserving
in interface DataType<Integer>
true
when natural order is preserved,
false
otherwise.public Order getOrder()
DataType
Order
imposed by this data type, or null when
natural ordering is not preserved. Value is either ascending or
descending. Default is assumed to be Order.ASCENDING
.
getOrder
in interface DataType<Integer>
public boolean isNullable()
DataType
DataType
s that support null should treat null as comparing
less than any non-null value for default sort ordering purposes.
isNullable
in interface DataType<Integer>
true
when null is supported, false
otherwise.public boolean isSkippable()
DataType
DataType
s that are not skippable can only be used as the
right-most field of a Struct
.
