Check config

overridables:

  • bool CheckConfig_impl(quiet); // rarely overridden
  • void CheckThisConfig_impl(quiet, &rval)
  • void CheckChildConfig_impl(quiet, &rval)

top guys:

  • bool CheckConfig(quiet) //calls _Gui with "no confirm"
  • bool CheckConfig_Gui(confirm_success, quiet)
    • this guy does the Start/End nesting thing, and gives feedback
  • taMisc::CheckConfigStart(confirm, quiet)
  • taMisc::CheckConfigEnd(ok)

use in pairs -- first Start controls mode/params any nested calls of End(false) force error state for everyone last End guy does gui stuff

  • taiMiscCore -- nogui feedback
  • taiMisc -- gui feedback

in all Check routines:

  • CheckError(test, quiet, rval, "msg") for taBase objects -- automatically adds the type and path name of the object, for much more informative and easy error msgs. Returns value of test so you can do: 
  if(CheckError(!ptr, quiet, rval, "pointer ptr is null")) {
    return false; // fatal
  }
  • taMisc::CheckError for errors
