The enumerated type for time units lacks microseconds

  • Key: UCM14-2
  • Status: open  
  • Source: THALES ( Thomas Vergnaud)
  • Summary:

    The additional component execution policies module defines an enumeration for time units (named ucm_time_unit_t) with s (second), ms (millisecond) and ns (nanosecond). Microsecond is missing, while it is commonly used in real-time systems.

sequence/const mapping

  • Key: UCM14-1
  • Status: open  
  • Source: Remedy IT ( Johnny Willemsen)
  • Summary:

    The bounded sequence maps to a std::array but that is very heavy in terms of memory management. In a lot of use cases a sequence bound is set to limit the size, but by mapping it to a std::array the result is that the maximum is allocated directly in memory. IDL to C+11 doesn't require this, it maps to a distinct type that supports the bound, but not to a std::array. Would recommend to update this mapping to match with IDL to C+11

    Also a constant is mapped to const, in a lot of cases it can be mapped to a constexpr, which is even better, see IDL to C++11
