    • configure

      public void configure() throws ConfigurationException
      Description copied from interface: IListener
      configure() is called once at startup of the framework in the configure() method of the owner of this listener. Purpose of this method is to reduce creating connections to databases etc. in the IPullingListener.getRawMessage(Map) method. As much as possible class-instantiating should take place in the configure() or open() method, to improve performance.

    • getMessageBrowser

      public IMessageBrowser<M> getMessageBrowser(ProcessState state)
      Description copied from interface: IProvidesMessageBrowsers
      returns a browser of messages that are in ProcessState 'state', and are stored in a storage managed by the listener itself (as opposed to a storage configured as a messageLog or errorStorage in the configuration).

      public String getStatusValue(ProcessState state)

    • getPhysicalDestinationName

      public String getPhysicalDestinationName()
      Description copied from class: JdbcFacade
      Returns the name and location of the database that this objects operates on. If no previous connection was made or it cannot determine the destination it returns 'unknown'
