Class Enum

water.Iced

water.parser.Enum

All Implemented Interfaces:

java.lang.Cloneable, Freezable

public final class Enum
extends Iced

Class for tracking enum columns. Basically a wrapper around non blocking hash map. In the first pass, we just collect set of unique strings per column (if there are less than MAX_ENUM_SIZE unique elements). After pass1, the keys are sorted and indexed alphabetically. In the second pass, map is used only for lookup and never updated. Enum objects are shared among threads on the local nodes!
