Lines Matching defs:State
22 * Linear or DAG of {@link State}s. StateMachine is by default a linear model, until
23 * {@link #addState(State, State)} is called. Each State has three status:
24 * STATUS_ZERO, STATUS_INVOKED, STATUS_EXECUTED. We allow client to run a State, which will
25 * put State in STATUS_INVOKED. A State will be executed when prior States are executed and
26 * Precondition for this State is true, then the State will be marked as STATUS_EXECUTED.
33 * No request on the State
42 * Somebody wants to run the State and the State was executed.

58 * Returns true if State can run, false otherwise. Subclass may override.

66 * @return True if the State has been executed.
