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