Real() [2/5] template<long int MinVal, long int MaxVal, long int DefaultVal = 0> drama::gitarg::Real< MinVal, MaxVal, DefaultVal >::Real ( const sds::Id &  Id, const std::string &  Name = "Argument1", const int  Position = 1, const double  Default = (double)DefaultVal, const Flags  flags = Flags::KeepErr  ) inline Constructor which constructs the value from an item in an SDS structure. The value is fetched from the named item (arg #2) within the SDS structure specified. or the Position (constructor arg #3) item in the structure if the item named does not exist. Note The DRAMA lock must be taken when executing this. If in a thread, the preference is to take it by constructing a drama::AccessDrama object to ensure the action context is correct. An alternative overload of this method will take the lock itself. Parameters Id The SDS structure. Name The name of the item within the structure. Position If the item does not exist by the name, then presume this position. Default The default value. If not specified, uses template argument "DefaultVal". flags Which GIT Flags to apply. If you specify KeepErr, then an exception is throw if the value in the SDS structure is invalid. If you don't specify KeepErr and and the SDS structure does not contain a value item, then the value is set to the supplied default.
