## Interface ProcessDAO

- All Known Implementing Classes:
    ProcessDaoImpl, ProcessDAOImpl

      public interface ProcessDAO

  BPEL process data access objects. Contains references to active process instances (`ProcessInstanceDAO` and messages bound for instances yet to be created or not yet correlated..

      Returns:
        qualified BPEL process name.

    - #### getVersion

          long getVersion()

      Get the process version
      Returns:

    - #### getCorrelator

          CorrelatorDAO getCorrelator(java.lang.String correlatorId)

      Get a message correlator instance.
      Parameters:
        `correlatorId` - correlator identifier
      Returns:
        correlator corresponding to the given identifier

    - #### createInstance

          ProcessInstanceDAO createInstance(CorrelatorDAO instantiatingCorrelator)

      Create a new process instance object.
      Parameters:
        `instantiatingCorrelator` - instantiating `CorrelatorDAO`
      Returns:
        newly generated instance DAO

    - #### getInstance

          ProcessInstanceDAO getInstance(java.lang.Long iid)

      Get a process instance (by identifier).
      Parameters:
        `iid` - unique instance identifier.
      Returns:
        DAO corresponding to the process instance

    - #### findInstance

          java.util.Collection<ProcessInstanceDAO> findInstance(CorrelationKey cckey)

      Locates a process instance based on a correlation key.
      Parameters:
        `cckey` - correlation key
      Returns:
        collection of `ProcessInstanceDAO` that match correlation key, ordered by date

    - #### removeRoutes

          void removeRoutes(java.lang.String routeId,
                          ProcessInstanceDAO target)

        `routeId` -

    - #### instanceCompleted

          void instanceCompleted(ProcessInstanceDAO instance)

      Callback indicating that a process instance has completed its duties.
      Parameters:
        `instance` - the completed `ProcessInstanceDAO`

    - #### deleteProcessAndRoutes

          void deleteProcessAndRoutes()

      Deletes only the process and routes without instances. This also deletes any static data to the process: correlators.
