Enum Class ReferentialAction

java.lang.Enum<ReferentialAction>

dev.frostlake.metastore.model.ReferentialAction

All Implemented Interfaces:

Serializable, Comparable<ReferentialAction>, Constable

public enum ReferentialAction
extends Enum<ReferentialAction>

A foreign-key referential action (ON DELETE / ON UPDATE). Informational only — the engine records but does not enforce these. getSqlText() is the canonical DDL spelling (with spaces, e.g. "NO ACTION", not the enum's underscores).

String	getSqlText()	The canonical SQL spelling used in DDL and SHOW output (e.g.
static ReferentialAction	valueOf(String name)	Returns the enum constant of this class with the specified name.

Enum Constant Details

NO_ACTION

public static final ReferentialAction NO_ACTION

RESTRICT

public static final ReferentialAction RESTRICT

CASCADE

public static final ReferentialAction CASCADE

SET_NULL

public static final ReferentialAction SET_NULL

SET_DEFAULT

public static final ReferentialAction SET_DEFAULT

Method Details

values

public static ReferentialAction[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static ReferentialAction 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.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

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

NullPointerException - if the argument is null

getSqlText

public String getSqlText()

The canonical SQL spelling used in DDL and SHOW output (e.g. "SET NULL").

fromString

public static ReferentialAction fromString(String value)

Parse a referential-action value case-insensitively; null/unrecognized → null (i.e. no action specified). Spaces and underscores are ignored so both spellings are accepted — the CREATE path yields "SET NULL" while the ALTER path's referentialOption().getText() yields "SETNULL"; both normalize here.
