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