Method Summary

Modifier and Type	Method and Description
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.
Object	create(double value) Create an object with the value.
double	get(Object o) Get the double data.
Object	getPrimitiveJavaObject(Object o) Get the Java Primitive object.
Object	set(Object o, double value) Set the object with the value.

Method Detail

get

public double get(Object o)

Description copied from interface: DoubleObjectInspector

Get the double data.

Specified by:

get in interface DoubleObjectInspector

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(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
