  29  * Custom statistic type created for the Sun ONE Application Server.
  30  * The goal is to be able to represent changing attribute values that are strings
  31  * in the form of Statistics. Semantically, it is analogous to a {@link CountStatistic},
  32  * the only difference being in the value that is returned. Unlike a CountStatistic
  33  * (which always is unidirectional), this Statistic type is not having any
  34  * specified direction, simply because there is no natural order. An example
  35  * of the values that an instance of this statistic type can assume is: A State
  36  * Statistic which can have "CONNECTED, CLOSED, DISCONNECTED" as the permissible
  37  * values and the current value can be any one of them (and them only).
  38  * The permissible values are upto a particular implementation.
