Public Member Functions

• option_set_container * operator() (int argc, char **argv, int filtc, char **filtv)

  This operator takes <argc,argv> as received by main function, then it takes a set of regular expressions defined by <filtc, filtv> and returns a set (vector) of option subsets.
  
  

Detailed Description

This class is designed to separate a set of command line options as received by

 main(int argc,
 char** argv) 

Options set

In the context of this class a pair of <int,char**> representing a set of option strings.

Option set filter

A regular expression which is applied on the given option set (usually full option set received by main()). If the option matches the filter it is copied to the option set associated with that filter.

Member Function Documentation

option_filter::option_set_container * DGD::option_filter::operator() (  int  argc, char **  argv, int  filtc, char **  filtv )

This operator takes <argc,argv> as received by main function, then it takes a set of regular expressions defined by <filtc, filtv> and returns a set (vector) of option subsets. First set is generated by the first filter, second set by the second filter and so on, the last set contains options which were not selected by any filter. so the following is always true result->size() == filtc + 1. Note that the returned option_set_container is dynamically allocated and must be deallocated by using explicit delete operator. See also: DGD::Debug
