Is DoubleWritable and DoubleObjectInspector doing the same thing in Hive UDF?

[Alex]

Hi,

can You guys tell me if below peice of two codes are returning the same
thing?

(((DoubleObjectInspector) ins2).get(obj)); and (DoubleWritable)obj).get(); from
below two  codes


code 1)

public Object get(Object name) {
  int pos = getPos((String)name);
  if(pos<0) return null;
  String f = "string";
  Object obj= list.get(pos);
  if(obj==null) return null;
  ObjectInspector ins = ((StructField)colnames.get(
pos)).getFieldObjectInspector();
  if(ins!=null) f = ins.getTypeName();
  switch (f) {
case "double" :  return ((DoubleWritable)obj).get();
case "bigint" :  return ((LongWritable)obj).get();
case "string" :  return ((Text)obj).toString();
default  :  return obj;
  }
}


Code 2)

public Object get(Object name) {

int pos = getPos((String) name);

if (pos < 0)

return null;

String f = "string";

String f1 = "string";

Object obj = list.get(pos);



if (obj == null)

return null;

ObjectInspector ins = ((StructField) colnames.get(pos)).
getFieldObjectInspector();

if (ins != null)

f = ins.getTypeName();





PrimitiveObjectInspector ins2 = (PrimitiveObjectInspector)
ins;

f1 = ins2.getPrimitiveCategory().name();





   switch (ins2.getPrimitiveCategory()) {

case DOUBLE:



return (((DoubleObjectInspector) ins2).get(obj));



case LONG:



   return  (((LongObjectInspector) ins2).get(obj));



   case STRING:

return (((StringObjectInspector)
ins2).getPrimitiveJavaObject(obj)).toString();



default:return obj;

}

 }
