  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<SortingData.NullHandling>
    Enclosing class:
    SortingData
    public static enum SortingData.NullHandling
extends java.lang.Enum<SortingData.NullHandling>
    Enum containing the different types of null handling strategies (i.e nulls first or nulls last). It also contains a value which indicates that the handling should be performed by the underlying infrastructure.

      • values

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

      • valueOf

        public static SortingData.NullHandling 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
