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 double get(Object o)

Description copied from interface: DoubleObjectInspector

Get the double data.

Specified by:

get in interface DoubleObjectInspector

create

public Object create(double value)

Description copied from interface: SettableDoubleObjectInspector

Create an object with the value.

Specified by:

create in interface SettableDoubleObjectInspector

set

public Object set(Object o,
         double value)

Description copied from interface: SettableDoubleObjectInspector

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 SettableDoubleObjectInspector
