Enum EmptyValueHandling

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<EmptyValueHandling>
    public enum EmptyValueHandling
extends java.lang.Enum<EmptyValueHandling>
    This enum offers various ways in which empty values (EmptyValue) may be handled during conversion.

    • Enum Constant Summary

      Enum Constants 
      Enum Constant Description
      CONVERT
      Empty values should be converted normally - which most likely means they will end up as a String.
      KEEP_AS_IS
      Empty values will not be converted.

      • CONVERT

        public static final EmptyValueHandling CONVERT
        Empty values should be converted normally - which most likely means they will end up as a String. However, the String won't be just any object, but the specific, reserved instance ParameterUtil.EMPTY_VALUE (so even if converted, one could perform an instance comparison to specifically detect empty values - however, this is discouraged and should only be used if it is not possible to simply turn off conversion of inexistent values via KEEP_AS_IS).

        This is the default if not specified otherwise in a ConversionContext.

      • KEEP_AS_IS

        public static final EmptyValueHandling KEEP_AS_IS
        Empty values will not be converted.

    • Method Detail

      • values

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

      • valueOf

        public static EmptyValueHandling 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
