Enum TerminalKind

java.lang.Object
java.lang.Enum<TerminalKind>
org.oristool.lello.parse.TerminalKind
All Implemented Interfaces:
Serializable, Comparable<TerminalKind>
public enum TerminalKind extends Enum<TerminalKind>
Represents the kind of a terminal symbol. The kind of a terminal symbol influences the behavior (precedence, associativity, etc...) of the parser when it encounters the symbol.

    • values

      public static TerminalKind[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
