Enum ClassInfo.Traversal

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<ClassInfo.Traversal>
    Enclosing class:
    ClassInfo
    public static enum ClassInfo.Traversal
extends java.lang.Enum<ClassInfo.Traversal>

    To all intents and purposes, the "real" class hierarchy and the mixin class hierarchy exist in parallel, this means that for some hierarchy validation operations we need to walk across to the other hierarchy in order to allow meaningful validation to occur.

    This enum defines the type of traversal operations which are allowed for a particular lookup.

    Each traversal type has a next property which defines the traversal type to use on the next step of the hierarchy validation. For example, the type IMMEDIATE which requires an immediate match falls through to NONE on the next step, which prevents further traversals from occurring in the lookup.

    • Enum Constant Summary

      Enum Constants 
      Enum Constant Description
      ALL
      Traversal is allowed at all stages.
      IMMEDIATE
      Traversal is allowed at the bottom of the hierarchy but no further.
      NONE
      No traversals are allowed.
      SUPER
      Traversal is allowed only on superclasses and not at the bottom of the hierarchy.

    • Method Detail

      • values

        public static ClassInfo.Traversal[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (ClassInfo.Traversal c : ClassInfo.Traversal.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static ClassInfo.Traversal valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null

      • next

        public ClassInfo.Traversal next()
        Return the next traversal type for this traversal type

      • canTraverse

        public boolean canTraverse()
        Return whether this traversal type allows traversal
