Class ATNState

  • Direct Known Subclasses:
    BasicState, BlockEndState, DecisionState, LoopEndState, RuleStartState, RuleStopState, StarLoopbackState

    public abstract class ATNState
    extends Object
    The following images show the relation of states and transitions for various grammar constructs.
    • Solid edges marked with an ε indicate a required EpsilonTransition.
    • Dashed edges indicate locations where any transition derived from Transition might appear.
    • Dashed nodes are place holders for either a sequence of linked BasicState states or the inclusion of a block representing a nested construct in one of the forms below.
    • Nodes showing multiple outgoing alternatives with a ... support any number of alternatives (one or more). Nodes without the ... only support the exact number of alternatives shown in the diagram.
