This class contains the state of an 'not' operator in the evaluation state tree. The not operator inverts the truth of the subexpression under it. It defaults to being true rather than being false at Startup. True at Startup means it will generate an event on newState such that parent expressions may turn true. It turns permenantly false when it receives an event from a subexpression and the subexpression quitted. It indicates the false state via an evaluateFalse call on its parent evaluator.

The following tables list the members exposed by the EvalNotStateNode type.

Public Methods

  NameDescription
Accept
Accept a visitor. Child classes are expected to invoke the visit method on the visitor instance passed in.
(Overrides .Accept(EvalStateNodeVisitor, Object).)
ChildrenAccept
Pass the visitor to all child nodes.
(Overrides .ChildrenAccept(EvalStateNodeVisitor, Object).)
Equals (Inherited from Object.)
EvaluateFalse
Indicate a change in truth value to false.

EvaluateTrue
Indicate a change in truth value to true.

GetHashCode (Inherited from Object.)
GetType (Inherited from Object.)
Quit
Stops the event expression or an instance of it. Child classes are expected to free resources and Stop any event listeners or remove any time-based callbacks.
(Overrides .Quit().)
Start
Starts the event expression or an instance of it. Child classes are expected to initialize and Start any event listeners or schedule any time-based callbacks as needed.
(Overrides .Start().)
ToString
Returns a String that represents the current Object.
(Overrides .ToString().)
