20.5. Salience State Example: Rule "Bootstrap"

rule Bootstrap
    when
        a : State(name == "A", state == State.NOTRUN )
    then
        System.out.println(a.getName() + " finished" );
        a.setState( State.FINISHED );
end

Result:

rule "A to B"
    when
        State(name == "A", state == State.FINISHED )
        b : State(name == "B", state == State.NOTRUN )
    then
        System.out.println(b.getName() + " finished" );
        b.setState( State.FINISHED );
end

Every action and the corresponding changes appear in the Working Memory.
The assertion of the State object A in the state NOTRUN activates the Bootstrap rule, while the assertions of the other State objects have no immediate effect.
The execution of rule Bootstrap changes the state of A to FINISHED, which, in turn, activates rule "A to B".
