Method Detail

get

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

Specified by:
get in interface LongObjectInspector

copyObject

public Object copyObject(Object o)
Description copied from interface: PrimitiveObjectInspector
Get a copy of the Object in the same class, so the return value can be stored independently of the parameter. If the Object is a Primitive Java Object, we just return the parameter since Primitive Java Object is immutable.

Specified by:
copyObject in interface PrimitiveObjectInspector

getPrimitiveJavaObject

public Object getPrimitiveJavaObject(Object o)
Description copied from interface: PrimitiveObjectInspector
Get the Java Primitive object.

Specified by:
getPrimitiveJavaObject in interface PrimitiveObjectInspector

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
