Enum TypeNullability

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<TypeNullability>
    public enum TypeNullability
extends java.lang.Enum<TypeNullability>
    Describes the instrinsic nullability of a data type as reported by the JDBC driver.

    • Enum Constant Summary

      Enum Constants 
      Enum Constant Description
      NON_NULLABLE
      The data type cannot accept nulls
      NULLABLE
      The data type can accept nulls
      UNKNOWN
      It is unknown if the data type accepts nulls

    • Method Detail

      • values

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

      • valueOf

        public static TypeNullability 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

      • interpret

        public static TypeNullability interpret​(short code)
        Based on the code retrieved from DatabaseMetaData.getTypeInfo() for the NULLABLE column, return the appropriate enum.
        Parameters:
        code - The retrieved code value.
        Returns:
        The corresponding enum.
