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

getPrimitiveJavaObject

public Date getPrimitiveJavaObject(Object o)
Description copied from interface: PrimitiveObjectInspector
Get the Java Primitive object.

Specified by:
getPrimitiveJavaObject in interface DateObjectInspector
Specified by:
getPrimitiveJavaObject in interface PrimitiveObjectInspector
