All Implemented Interfaces:

Cloneable, ConstantObjectInspector, ObjectInspector, VoidObjectInspector, PrimitiveObjectInspector

public class WritableVoidObjectInspector
extends AbstractPrimitiveWritableObjectInspector
implements VoidObjectInspector, ConstantObjectInspector

A WritableVoidObjectInspector inspects a NullWritable Object. Note that this is also a constant object inspector.

Method Detail

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

getWritableConstantValue

public Object getWritableConstantValue()

Specified by:

getWritableConstantValue in interface ConstantObjectInspector

getPrimitiveJavaObject

public Object getPrimitiveJavaObject(Object o)

Description copied from interface: PrimitiveObjectInspector

Get the Java Primitive object.

Specified by:

getPrimitiveJavaObject in interface PrimitiveObjectInspector

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
