/**
 * Returns set of string. This is a convenient method for adding a set of

 * want to add a string to the map.//  w  w  w. j a  va  2 s  . c o  m
 *
 * @param key Key to the entry in the map.
 * @param map Map of String to Set of String.
 * @param value Value to be added to the map referenced by <code>key</code>.
 * @return Set of string.
