Enum Constant Detail

### NONE

    public static final OptimisticLockType NONE

  no optimistic locking

### VERSION

    public static final OptimisticLockType VERSION

  use a column version

### DIRTY

    public static final OptimisticLockType DIRTY

  dirty columns are compared

### ALL

    public static final OptimisticLockType ALL

  all columns are compared

Method Detail

### values

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

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

### valueOf

    public static OptimisticLockType 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
