@InterfaceAudience.Public @InterfaceStability.Evolving public class RawString extends Object implements DataType<String>
DataType for interacting with values encoded using
Bytes.toBytes(String). Intended to make it easier to transition
away from direct use of Bytes.| Modifier and Type | Field and Description |

String |
decode(PositionedByteRange src)
Read an instance of
T from the buffer src. |
int |
encode(PositionedByteRange dst,
String val)
Write instance
val into buffer dst. |
Class<String> |
encodedClass()
Inform consumers over what type this
DataType operates. |
int |
encodedLength(String val)
Inform consumers how long the encoded
byte[] will be. |
Order |
getOrder()
Retrieve the sort
Order imposed by this data type, or null when
natural ordering is not preserved. |
boolean |
isNullable()
Indicates whether this instance supports encoding null values.
|
boolean |
isOrderPreserving()
Indicates whether this instance writes encoded
byte[]'s
which preserve the natural sort order of the unencoded value. |
boolean |
isSkippable()
Indicates whether this instance is able to skip over it's encoded value.
|
int |
skip(PositionedByteRange src)
Skip
src's position forward over one encoded value. |

public boolean isOrderPreserving()
DataTypebyte[]'s
which preserve the natural sort order of the unencoded value.isOrderPreserving in interface DataType<String>true when natural order is preserved,
false otherwise.public Order getOrder()
DataTypeOrder 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.public boolean isNullable()
DataTypeDataTypes that support null should treat null as comparing
less than any non-null value for default sort ordering purposes.isNullable in interface DataType<String>true when null is supported, false otherwise.public boolean isSkippable()
DataTypeDataTypes that are not skippable can only be used as the
right-most field of a Struct.isSkippable in interface DataType<String>public int skip(PositionedByteRange src)
