Method Summary

BytesWritable	copyObject(Object o) Get a copy of the Object in the same class, so the return value can be stored independently of the parameter.
BytesWritable	create(byte[] bb) Create an object with the value.
BytesWritable	create(BytesWritable bw) Create an object with the value.
byte[]	getPrimitiveJavaObject(Object o) Get the Java Primitive object.
BytesWritable	getPrimitiveWritableObject(Object o) Return the data in an instance of primitive writable Object.
BytesWritable	set(Object o, byte[] bb) Set the object with the value.
BytesWritable	set(Object o, BytesWritable bw) Set the object with the value.

Method Detail

copyObject

public BytesWritable 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 byte[] getPrimitiveJavaObject(Object o)

Description copied from interface: PrimitiveObjectInspector

Get the Java Primitive object.

Specified by:

getPrimitiveJavaObject in interface BinaryObjectInspector

Specified by:

getPrimitiveJavaObject in interface PrimitiveObjectInspector

getPrimitiveWritableObject

public BytesWritable 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 BinaryObjectInspector

Specified by:

getPrimitiveWritableObject in interface PrimitiveObjectInspector

Overrides:

getPrimitiveWritableObject in class AbstractPrimitiveWritableObjectInspector

set

public BytesWritable set(Object o,
                         byte[] bb)

Description copied from interface: SettableBinaryObjectInspector

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 SettableBinaryObjectInspector

set

public BytesWritable set(Object o,
                         BytesWritable bw)

Description copied from interface: SettableBinaryObjectInspector

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 SettableBinaryObjectInspector

create

public BytesWritable create(byte[] bb)

Description copied from interface: SettableBinaryObjectInspector

Create an object with the value.

Specified by:

create in interface SettableBinaryObjectInspector

create

public BytesWritable create(BytesWritable bw)

Description copied from interface: SettableBinaryObjectInspector

Create an object with the value.

Specified by:

create in interface SettableBinaryObjectInspector
