Enum Untyped

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<Untyped>, ComplexType, SchemaComponent, SchemaType
    public enum Untyped
extends java.lang.Enum<Untyped>

    This class has a singleton instance which represents the complex type xdt:untyped, used for elements that have not been validated.

    • Enum Constant Detail

      • INSTANCE

        public static final Untyped INSTANCE

    • Method Detail

      • values

        public static Untyped[] 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 (Untyped c : Untyped.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static Untyped 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

      • getInstance

        public static Untyped getInstance()
        Get the singular instance of this class

      • getRedefinitionLevel

        public int getRedefinitionLevel()
