    - #### REQUIRED

          public static final UnitOfWorkPropagation.Propagation REQUIRED

      Default propagation behavior. Behavior:
      If no current transaction: creates a new UnitOfWork
      If there is a current UnitOfWork: use the current UnitOfWork.

    - #### MANDATORY

          public static final UnitOfWorkPropagation.Propagation MANDATORY

      Behavior:
      If no current UnitOfWork: throw an exception
      If there is a current UnitOfWork: use the current UnitOfWork.

    - #### REQUIRES_NEW

          public static final UnitOfWorkPropagation.Propagation REQUIRES_NEW

      Behavior:
      If no current UnitOfWork: creates a new UnitOfWork
      If there is a current UnitOfWork: suspend the current UnitOfWork and create a new UnitOfWork.

  - ### Method Detail

    - #### values

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

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

    - #### valueOf

          public static UnitOfWorkPropagation.Propagation 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
