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

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<T>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<T>public int skip(PositionedByteRange src)
DataTypesrc's position forward over one encoded value.Copyright © 2007–2019 The Apache Software Foundation. All rights reserved.
