 * @param useHashKeys use <code>equals()</code> and <code>hashCode()</code> methods by storing objects in hash maps
 * @param matchingMode to optimize storing and searching, and to specify which matching mode should used
 * @param uniqueMatch keep in the lookup only the last put object, but store the current number of same values for

 * @param keepAllValues keep all identical values (with same key values) in each list of each key
 * @param countValuesForEachKey force internal count of values
