Method Detail

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

getPrimitiveJavaObject

public Object getPrimitiveJavaObject(Object o)

Description copied from interface: PrimitiveObjectInspector

Get the Java Primitive object.

Specified by:

getPrimitiveJavaObject in interface PrimitiveObjectInspector

Overrides:

getPrimitiveJavaObject in class AbstractPrimitiveJavaObjectInspector

create

public Object create(byte val)

Description copied from interface: SettableByteObjectInspector

Create an object with the value.

Specified by:

create in interface SettableByteObjectInspector

set

public Object set(Object o,
         byte val)

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

get

public byte get(Object o)

Description copied from interface: ByteObjectInspector

Get the byte data.

Specified by:

get in interface ByteObjectInspector
