Enum Constant Detail

NULL

@Support
public static final Nullability NULL

The data type is explicitly nullable.

NOT_NULL

@Support
public static final Nullability NOT_NULL

The data type is explicitly not nullable.

DEFAULT

@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).

Method Detail

values

public static Nullability[] 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 (Nullability c : Nullability.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Nullability valueOf(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:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

of

public static 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.
