DDS4CCM_ — Supporting Content Filtered Topics

  • Key: DDS4CCM_-100
  • Legacy Issue Number: 15172
  • Status: closed  
  • Source: Remedy IT ( Johnny Willemsen)
  • Summary:

    The current QueryFilter in the spec seems to match best to a QueryCondition.
    But DDS also provides the ContentFilteredTopic support, that doesn't seem to
    be available at the ccm-dds level, is this intended?

  • Disposition: Resolved — DDS4CCM 1.0b2
  • Disposition Summary:

    The resolution is to add on the reading-side DDS ports a filter attribute and a
    basic port to change filter parameters when appropriate (this basic port will be
    used in the port and provided in the associated mirrorport). This disposal implies
    to add configuration attributes in porttype definitions.
    In addition, for clarity purpose, the formerly named "filter" attribute on the Reader
    interface is renamed "query" and inside the QueryFilter structure, the first field
    (formerly "query") is renamed "expression" and the second (formerly
    "query_parameters") simplified to become "parameters".
    • The current QueryFilter is definitively intended to match the DDS query.
    ContentFilteredTopic is also a very important DDS feature that should be
    accessible through ccm-dds.
    • Configuration attributes fin porttype definitions is also useful for many
    other uses of the GIS (was missing)
