  - ### Method Detail

    - #### values

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

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

    - #### valueOf

          public static ActiveTransactionRegistry 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

    - #### getTimeout

          public long getTimeout(TimeUnit unit)

    - #### register

          public void register(org.eclipse.rdf4j.http.server.repository.transaction.Transaction txn)

      Parameters:
        `txn` -

    - #### getTransaction

          public org.eclipse.rdf4j.http.server.repository.transaction.Transaction getTransaction(UUID id)

    - #### active

          public void active(org.eclipse.rdf4j.http.server.repository.transaction.Transaction txn)

      Resets transaction timeout. If transaction has already timed-out, reinsert the transaction.
      Parameters:
        `txn` -

    - #### deregister

          public void deregister(org.eclipse.rdf4j.http.server.repository.transaction.Transaction transaction)

      Parameters:
        `transaction` -
