  - ### Method Detail

    - #### values

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

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

    - #### valueOf

          public static TransactionState valueOf(java.lang.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:
        `java.lang.IllegalArgumentException` - if this enum type has no constant with the specified name
        `java.lang.NullPointerException` - if the argument is null

    - #### isValidTransition

          public final boolean isValidTransition(TransactionState toState)

      Is the transition to `toState` valid from this state.
      Parameters:
        `toState` - The next state
      Returns:
        `true` transition is valid

    - #### validTransitionSet

          public final java.util.Set<TransactionState> validTransitionSet()

      Returns:
        Set of valid transitions from this state
