DDSPSMC — Improving usability of Reference class

Open Closed All
  • Key: DDSPSMC-6
  • Legacy Issue Number: 16339
  • Status: closed  
  • Source: Real-Time Innovations ( Sumant Tambe)
  • Summary:

    1. Safety of Reference<D> class should be improved by adding "explicit" keyword in the following constructors:

    template <typename D>
    Reference(const Reference<D>& ref);

    template <typename R>
    Reference(const R& that);

    Reference(const DELEGATE_REF_T& ref);

    2. With just member operator== and operator!= functions, Reference<D> can't be used in expressions like

    if(dds::null == r)

    { ... }

    Proposed solution: Add the following free functions in dds::core in Reference.hpp.

    template <class D>
    bool operator == (dds::null_type,
    const Reference<D> & r)

    { return r.is_nil(); }

    template <class D>
    bool operator != (dds::null_type,
    const Reference<D> & r)

    { return !r.is_nil(); }
