aoqi@0 | 30 | * Custom statistic type created for the Sun ONE Application Server. |
aoqi@0 | 31 | * The goal is to be able to represent changing attribute values that are strings |
aoqi@0 | 32 | * in the form of Statistics. Semantically, it is analogous to a {@link CountStatistic}, |
aoqi@0 | 33 | * the only difference being in the value that is returned. Unlike a CountStatistic |
aoqi@0 | 34 | * (which always is unidirectional), this Statistic type is not having any |
aoqi@0 | 35 | * specified direction, simply because there is no natural order. An example |
aoqi@0 | 36 | * of the values that an instance of this statistic type can assume is: A State |
aoqi@0 | 37 | * Statistic which can have "CONNECTED, CLOSED, DISCONNECTED" as the permissible |
aoqi@0 | 38 | * values and the current value can be any one of them (and them only). |
aoqi@0 | 39 | * The permissible values are upto a particular implementation. |
