interface - C++ compile-time un-implmented check -


we have several c++ functions implemented in phase 2 of our project part of public interface or respective classes , modules. because part of public interface, think should present, @ least in headers, during phase 1 still thinking them implement rest of classes. however, since unimplemented, want no 1 call them. check occur @ compile time, ensure correctness.

my desires are:

  • compile time (could error or warning; warnings better because more flexible - can selectively turn them off)

  • works on g++4.8.1 , doesn't kill build under visual studio 2013 (we use visual studio/visualassistx editor refactoring tools don't work without building)

  • not hard understand done , why

  • functions present in class documentation (we can include \warning not implemented in phase 1 notation doxygen pick up)

i considering 3 options:

  • a belt , suspenders approach of marking them deprecated (which generate warning) , throwing custom exception - want except compiler warning "deprecated" opposite of real situation: deprecated method works won't work later; method work later not work now

  • another answer tells how forbid using function while still having exist - unreadable , hard search for. plus, compile-time error - can't let functions call if change our minds - or nothing. , making every unimplemented function template makes me wonder if trick work. example, virtual functions can't templates.

  • just putting them in comment - keeps people calling them, don't show in auto-generated documentation (and can't decide later have selective calling)

is there better way? , if not there reason prefer template or comment options on deprecated option?

as alternative:

you can declare them without definition, link error.
may provide library not_yet_implemented empty definition allow premature usage of these functions.

or

mark method deleted: = delete, wrapping in macro

#define not_yet_implemented = delete
