All Implemented Interfaces:

MapKI<String>, Serializable, Cloneable, Writable

public class HMapSIW
extends HMapKI<String>
implements Writable

Writable representing a map where keys are Strings and values are ints. This class is specialized for String objects to avoid the overhead that comes with wrapping Strings inside Text objects.
