/**
 * Wrapper class to make a TShortList conform to the java.util.List API.

 * APIs into their Trove primitive analogs.
 * 
 * Note that wrapping and unwrapping primitive values is extremely inefficient.  If
 * possible, users of this class should override the appropriate methods in this class
 * and use a table of canonical values.
