All Implemented Interfaces:

java.lang.Cloneable, State

public abstract class AbstractStateWithGen

extends AbstractState

Optional basis for class implementing State interface. Derived classes constructor must fill the protected variables. Add necessary state information and properties. This implementation uses ActionGenerator and StateGenerator to respond to State.getActions() and State.getNextStates(lnsc.page.Action) (and for State#getActionsEnumerator) calls. When states are not observable, it uses a (@link StateGenerator} with null action to generate the observable states for the agents. It does not support local Do or Undo operation (within an instance do operation) nor clone operation (by default). State and Action generators properties should be passed to to local variable (isDeterministic, areActionsFixed, ActionCount), oservable state generator should be should be deterministic (return a single state).
