Enum Class Nullability

All Implemented Interfaces:
Serializable, Comparable<Nullability>, Constable

public enum Nullability extends Enum<Nullability>
An enum that specifies the nullability of a DataType.

  • Enum Constant Details

    • NULL

      @NotNull @Support public static final Nullability NULL
      The data type is explicitly nullable.
    • NOT_NULL

      @NotNull @Support public static final Nullability NOT_NULL
      The data type is explicitly not nullable.

      @NotNull @Support public static final Nullability DEFAULT
      Default behaviour for data types.

      The interpretation of this value depends on the context in which a DataType is used:

      • CREATE TABLE: The data type is implicitly nullable (or explicitly, if the underlying database does not support implicit nullability or defaults to implicit non-nullability).
      • ALTER TABLE … ALTER COLUMN … SET TYPE: The data type's nullability will not be modified by jOOQ (but it may well be modified by the database, e.g. SQLDialect.MYSQL or SQLDialect.SQLSERVER).

    • values

      public static Nullability[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      an array containing the constants of this enum class, in the order they are declared
    • valueOf

      public static Nullability valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      name - the name of the enum constant to be returned.
      the enum constant with the specified name
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null
    • of

      @NotNull public static @NotNull Nullability of(boolean nullability)
      Get the explicit Nullability corresponding to a boolean value.
    • nullable

      public boolean nullable()
      Whether this nullability encodes an explicitly or implicitly nullable type.
