Method Detail

getPrimitiveWritableObject

public Object getPrimitiveWritableObject(Object o)
Description copied from interface: PrimitiveObjectInspector
Return the data in an instance of primitive writable Object. If the Object is already a primitive writable Object, just return o.

Specified by:
getPrimitiveWritableObject in interface PrimitiveObjectInspector

get

public byte get(Object o)
Description copied from interface: ByteObjectInspector
Get the byte data.

Specified by:
get in interface ByteObjectInspector

create

public Object create(byte value)
Description copied from interface: SettableByteObjectInspector
Create an object with the value.

Specified by:
create in interface SettableByteObjectInspector

set

public Object set(Object o,
                  byte value)
Description copied from interface: SettableByteObjectInspector
Set the object with the value. Return the object that has the new value. In most cases the returned value should be the same as o, but in case o is unmodifiable, this will return a new object with new value.

Specified by:
set in interface SettableByteObjectInspector
