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 long get(Object o)
Description copied from interface: LongObjectInspector
Get the long data.

Specified by:
get in interface LongObjectInspector

create

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

Specified by:
create in interface SettableLongObjectInspector

set

public Object set(Object o,
                  long value)
Description copied from interface: SettableLongObjectInspector
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 SettableLongObjectInspector
