public abstract class LazyBinaryPrimitive<OI extends ObjectInspector,T extends Writable>
extends LazyBinaryObject<OI>

Defines a LazyBinaryPrimitive. data will be initialized to corresponding types in different LazyBinary primitive classes. For example, data will be a BooleanWritable in the LazyBinaryBoolean class. There is no null flag any more,

Method Detail

getObject

public java.lang.Object getObject()

Returns the primitive object represented by this LazyBinaryObject. This is useful because it can make sure we have "null" for null objects.

Specified by:

getObject in class LazyObjectBase

getWritableObject

public T getWritableObject()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

hashCode

public int hashCode()

Specified by:

hashCode in class LazyBinaryObject<OI extends ObjectInspector>
