public void init(ByteArrayRef bytes,
int start,
int length)
- Description copied from class:
LazyBinaryObject
- Set the data for this LazyBinaryObject. We take ByteArrayRef instead of
byte[] so that we will be able to drop the reference to byte[] by a single
assignment. The ByteArrayRef object can be reused across multiple rows.
Never call this function if the object represent a null!!!
- Specified by:
init
in class LazyBinaryObject<WritableVoidObjectInspector>
- Parameters:
bytes
- The wrapper of the byte[].start
- The start position inside the bytes.length
- The length of the data, starting from "start"- See Also:
