Method Summary
 Object copyObject(Object o)
          Get a copy of the Object in the same class, so the return value can be stored independently of the parameter.

          Get the boolean data.
 Object getPrimitiveJavaObject(Object o)
          Get the Java Primitive object.
 Object set(Object o, boolean value)
          Set the object with the value.

Method Detail

get

public boolean get(Object o)
Description copied from interface: BooleanObjectInspector
Get the boolean data.

Specified by:
get in interface BooleanObjectInspector

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(boolean value)
Description copied from interface: SettableBooleanObjectInspector
Create an object with the value.

Specified by:
create in interface SettableBooleanObjectInspector

set

public Object set(Object o,
                  boolean value)
Description copied from interface: SettableBooleanObjectInspector
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 SettableBooleanObjectInspector
