public class LazyArray
extends LazyNonPrimitive<LazyListObjectInspector>

LazyArray stores an array of Lazy Objects. LazyArray does not deal with the case of a NULL array. That is handled by the parent LazyObject.

Method Summary

List<Object>	getList() Returns the List of actual primitive objects.
Object	getListElementObject(int index) Returns the actual primitive object at the index position inside the array represented by this LazyObject.
int	getListLength() Returns -1 for null array.
void	init(ByteArrayRef bytes, int start, int length) Set the row data for this LazyArray.
