Enum DuplicateKeyStrategy

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<DuplicateKeyStrategy>

    public enum DuplicateKeyStrategy
    extends java.lang.Enum<DuplicateKeyStrategy>
    An enum containing all supported behaviors for duplicate keys
    • Enum Constant Summary

      Enum Constants 
      Enum Constant Description
      DUPLICATE
      Wraps duplicate values inside an array, effectively treating them as if they were declared as one
      LAST_WINS
      Only the last encountered value is significant, all previous occurrences are silently discarded
      UNIQUE
      Throws an exception when a key is encountered multiple times within the same object

      • values

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

        public static DuplicateKeyStrategy 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
