Enum JoinType

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

    public enum JoinType
    extends java.lang.Enum<JoinType>
    Defines the three varieties of join.

    Support for RIGHT outer joins is not required. Applications which make use of right joins might not be portable between providers or between SQL databases.

    Since:
    2.0

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

        public static JoinType 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
