Issue 16886: Getter/Setter for member arrays (dds-psm-cxx-ftf)
Source: Real-Time Innovations (Dr. Sumant Tambe, sumant(at)rti.com)
Nature: Enhancement
Severity: Critical
Summary: The specification maps IDL array to C++ native array. There are two possible alternatives as far as getter/setter functions are concerned.


class Foo {
  char data[10]; 
public:
  char * begin_data() { return data; }
  char * end_data()   { return data + 10; }


  void data(char * begin, char *end) {}


  template <class Iter>
  void data(Iter begin, Iter end) {}
};


AND


class Foo {
  char data[10]; 
public:
  char * data() { return data; }
  size_t data_size()  { return 10; }
  void data(char *ptr, size_t size) {}
};

The first version is more consistent with modern C++ usage of iterators. In either case a convention must be defined for portability. This may also be applicable to idl sequences.
