public class State extends Object
StateMachine
. Normally you wouldn't create
instances of this class directly but rather use the
State
annotation to define
your states and then let StateMachineFactory
create a
StateMachine
for you.
State
s inherits Transition
s from
their parent. A State
can override any of the parents
Transition
s. When an Event
is processed the Transition
s
of the current State
will be searched for a Transition
which
can handle the event. If none is found the State
's parent will be
searched and so on.
