    • closeSequence

      Sequence closeSequence(String sequenceId) throws UnknownSequenceException
      Closes an existing sequence. The closed sequence is still kept in the internal sequence storage
      Parameters:
      sequenceId - the unique sequence identifier
      Returns:
      closed sequence object
      Throws:
      UnknownSequenceException
    • createOutboundSequence

      Sequence createOutboundSequence(String sequenceId, String strId, long expirationTime) throws DuplicateSequenceException
      Creates a new outbound sequence object with a given Id. It is assumed that RM handshake has been already established, thus no RM handshake is performed.
      Parameters:
      sequenceId - identifier of the new sequence
      strId - security reference token identifier which this session is bound to
      expirationTime - expiration time of the sequence in milliseconds; value of com.sun.xml.ws.rm.policy.Configuration#UNSPECIFIED means that this sequence never expires.
      Returns:
      newly created inbound sequence
      Throws:
      DuplicateSequenceException - in case a sequence instance with this identifier is already registered with this sequence manager
    • createInboundSequence

      Sequence createInboundSequence(String sequenceId, String strId, long expirationTime) throws DuplicateSequenceException
      Creates a new inbound sequence object
      Parameters:
      sequenceId - identifier of the new sequence
      strId - security reference token identifier which this session is bound to
      expirationTime - expiration time of the sequence in milliseconds; value of com.sun.xml.ws.rm.policy.Configuration#UNSPECIFIED means that this sequence never expires.
      Returns:
      newly created inbound sequence
      Throws:
      DuplicateSequenceException - in case a sequence instance with this identifier is already registered with this sequence manager
    • generateSequenceUID

      String generateSequenceUID()
      Generates a unique identifier of a sequence
      Returns:
      new unique sequence identifier which can be used to construct a new sequence.
    • getSequence

      Sequence getSequence(String sequenceId) throws UnknownSequenceException
      Retrieves an existing sequence from the internal sequence storage
      Parameters:
      sequenceId - the unique sequence identifier
      Returns:
      sequence identified with the sequenceId identifier
      Throws:
      UnknownSequenceException - in case no such sequence is registered within the sequence manager
    • getInboundSequence

      Sequence getInboundSequence(String sequenceId) throws UnknownSequenceException
      Retrieves an existing inbound sequence from the internal sequence storage
      Parameters:
      sequenceId - the unique sequence identifier
      Returns:
      sequence identified with the sequenceId identifier
      Throws:
      UnknownSequenceException - in case no such sequence is registered within the sequence manager or in case the registered sequence was not created as inbound.
    • getOutboundSequence

      Sequence getOutboundSequence(String sequenceId) throws UnknownSequenceException
      Retrieves an existing outbound sequence from the internal sequence storage
      Parameters:
      sequenceId - the unique sequence identifier
      Returns:
      sequence identified with the sequenceId identifier
      Throws:
      UnknownSequenceException - in case no such sequence is registered within the sequence manager or in case the registered sequence was not created as outbound.
    • isValid

      boolean isValid(String sequenceId)
      Provides information on whether the sequence identifier is a valid identifier that belongs to an existing sequence registered with the sequence manager.
      Parameters:
      sequenceId - sequence identifier to be checked
      Returns:
      true in case the sequence identifier is valid, false otherwise
    • terminateSequence

      Sequence terminateSequence(String sequenceId) throws UnknownSequenceException
      Terminates an existing sequence by calling the Sequence.preDestroy() method. In addition to this, the terminated sequence is removed from the internal sequence storage
      Parameters:
      sequenceId - the unique sequence identifier
      Returns:
      terminated sequence object
      Throws:
      UnknownSequenceException - in case no such sequence is registered within the sequence manager
    • bindSequences

      void bindSequences(String referenceSequenceId, String boundSequenceId) throws UnknownSequenceException
      Binds two sequences together. This method is mainly intended to be used for binding together request and response sequences.
      Parameters:
      referenceSequenceId - a reference sequence identifier to which the other sequence shall be bound.
      boundSequenceId - a bound sequence identifier
      Throws:
      UnknownSequenceException - in case any of the sequence identifiers does not represent a valid sequence
    • getBoundSequence

      Sequence getBoundSequence(String referenceSequenceId) throws UnknownSequenceException
      Retrieves a sequence previously bound to the reference sequence
      Parameters:
      referenceSequenceId - a reference sequence identifier to which the other sequence has been bound.
      Returns:
      bound sequence or null in case no sequence is bound to the reference sequence
      Throws:
      UnknownSequenceException - in case no such reference sequence is registered within the sequence manager
    • onMaintenance

      boolean onMaintenance()
      Terminates all sequences that became expired in the meantime and removes all previously terminated sequences that were terminated sooner than a pre-configured period of time.

      This maintenance method is intended to be called externally by a SequenceMaintenanceTask instance associated with this SequenceManager.

      Returns:
      true if the next maintenance execution task is supposed to be scheduled, false otherwise.
    • invalidateCache

      void invalidateCache()
      Instructs the SequenceManager instance to invalidate it's local cache. This prevents stale data being used and ensures that fresh data are loaded from the RM HA backing stores.
    • dispose

      void dispose()
      Tells the SequenceManager that it is going to be disposed. An implementation of this interface can use the method to do the necessary resource cleanup.
