Enum OptimisticLockStyle

java.lang.Object

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.

This enumeration is mainly for internal use, since it is isomorphic to OptimisticLockType.

Enum Constant Detail

NONE

public static final OptimisticLockStyle NONE

no optimistic locking

VERSION

public static final OptimisticLockStyle VERSION

use a dedicated version column

DIRTY

public static final OptimisticLockStyle DIRTY

dirty columns are compared

ALL

public static final OptimisticLockStyle ALL

all columns are compared

Method Detail

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 name

NullPointerException - if the argument is null

isAllOrDirty

isAll

public boolean isAll()

isDirty

getOldCode

@Deprecated(since="6.2",
            forRemoval=true)
public int getOldCode()

Deprecated, for removal: This API element is subject to removal in a future version.

these integer codes have not been used for a long time

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 time

Given 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:

IllegalArgumentException - If the code did not match any legacy constant.
