Enum OptimisticLockStyle

- java.lang.Enum<OptimisticLockStyle>

- org.hibernate.engine.OptimisticLockStyle

- All Implemented Interfaces:
Serializable
,Comparable<OptimisticLockStyle>
public enum OptimisticLockStyle extends Enum<OptimisticLockStyle>
Describes how an entity should be optimistically locked.- API Note:
- This enumeration is mainly for internal use, since it
is isomorphic to
OptimisticLockType
. In the future, it would be nice to replace them both with a neworg.hibernate.OptimisticLockCheck
enum.

values
public static OptimisticLockStyle[] 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 (OptimisticLockStyle c : OptimisticLockStyle.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static OptimisticLockStyle 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 nameNullPointerException
- if the argument is null

interpretOldCode
@Deprecated(since="6.2", forRemoval=true) public static OptimisticLockStyle interpretOldCode(int oldCode)
Deprecated, for removal: This API element is subject to removal in a future version.these integer codes have not been used for a long timeGiven an old code (one of the int constants from Cascade), interpret it as one of the new enums.- Parameters:
oldCode
- The old int constant code- Returns:
- The interpreted enum value
- Throws:
