  • Method Details

    • addRemoteServiceListener

      void addRemoteServiceListener(IRemoteServiceListener listener)
      Add listener for remote service registration/unregistration for this container
      Parameters:
      listener - notified of service registration/unregistration events. Must not be null .

    • removeRemoteServiceListener

      void removeRemoteServiceListener(IRemoteServiceListener listener)
      Remove remote service registration/unregistration listener for this container.
      Parameters:
      listener - to remove. Must not be null .

    • getRemoteServiceReferences

      IRemoteServiceReference[] getRemoteServiceReferences(ID target, ID[] idFilter, String clazz, String filter) throws InvalidSyntaxException, ContainerConnectException
      Returns an array of IRemoteServiceReference objects. The returned array of IRemoteServiceReference objects contains services that were registered under the specified class and match the specified idFilter, and filter criteria.

      Note this method assumes that the enclosing container has previously been connected, and uses the idFilter to filter among targets within the previously connected set of container IDs. To request connection as part of reference lookup, see getRemoteServiceReferences(ID, String, String).

      The list is valid at the time of the call to this method, however since the Framework is a very dynamic environment, services can be modified or unregistered at anytime.

      target is a remote container to connect to. If null, no connection attempt is made.

      idFilter is used to select a registered services that were registered by a given set of containers with id in idFilter. Only services exposed by a container with id in idFilter will be returned. If idFilter is null, all containers are considered to match the filter.

      filter is used to select the registered service whose properties objects contain keys and values which satisfy the filter. See Filter for a description of the filter string syntax. If filter is null, all registered services are considered to match the filter. If filter cannot be parsed, an InvalidSyntaxException will be thrown with a human readable message where the filter became unparsable.

      Parameters:
      target - a target container to connect to if enclosing container is not already connected. May be null.
      idFilter - an array of ID instances that will restrict the search for matching container ids If null, all remote containers will be considered in search for matching IRemoteServiceReference instances. May be null.
      clazz - the fully qualified name of the interface class that describes the desired service. Must not be null.
      filter - The filter criteria. May be null.
      Returns:
      Array of IRemoteServiceReferences matching given search criteria or null if no services are found that match the search.
      Throws:
      InvalidSyntaxException - If filter contains an invalid filter string that cannot be parsed.
      ContainerConnectException - if container cannot connect
