DDSXTY13 — DynamicType / DynamicTypeBuilder multiplicity of members

  • Key: DDSXTY13-11
  • Status: closed  
  • Source: Airbus Group ( Mr. Oliver M. Kellogg)
  • Summary:

    In the DDS-XTypes 1.2beta1 document, the UML class diagram in section Figure 30 on p. 175 does not show the multiplicity relationship between DynamicType and DynamicTypeMember for the case of aggregated types.
    In other words, the fact that a DynamicType struct/union/valuetype may have more than one member is not visible in the diagram.

    The section DynamicTypeBuilder does define an operation add_member which can be used to add members to aggregated types. However, DynamicTypeBuilder also does not provide a method for iterating over the members thus added.

    If it is intended that the management of and iteration over the sequence of DynamicTypeMembers shall lie outside of DynamicType / DynamicTypeBuilder, I suggest adding an explanation to that end.

  • Disposition: Resolved — DDS-XTypes 1.3
  • Disposition Summary:

    Update Figure 30 'Dynamic Type' and operations of DynamicTypeBuilder and DynamicType

    Update the of multiplicity of DynamicTypeMember in Figure 30 'Dynamic Type' (section from "0..1" to "0..*"

    Add operations to 'DynamicTypeBuilder' that allow figuring out the number of members and iterate over them.
    Add operations to 'DynamicType' to find the number of members and iterate over them.

    Order operations alphabetically.
