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(byte value) Create an object with the value.
byte	get(Object o) Get the byte data.
Object	getPrimitiveJavaObject(Object o) Get the Java Primitive object.
Object	set(Object o, byte value) Set the object with the value.

public WritableByteObjectInspector()

Method Detail

get

public byte get(Object o)

Description copied from interface: ByteObjectInspector

Get the byte data.

Specified by:

get in interface ByteObjectInspector

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(byte value)

Description copied from interface: SettableByteObjectInspector

Create an object with the value.

Specified by:

create in interface SettableByteObjectInspector

set

public Object set(Object o,
                  byte value)

Description copied from interface: SettableByteObjectInspector

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 SettableByteObjectInspector
