We could either implement simple chaining for variable maps, or
|
|
implement generic composition classes. The former was choosen,
|
|
mostly because of simplicity.
|
|
|
|
There were two implementation approaches for multiple option
|
|
occurrences in options_and_arguments. First is store them
|
|
separately. The advantage is that it's easy to obtain all
|
|
occurrences before certain position on command line. The
|
|
disadvantage is that we cannot return a reference to
|
|
vector<vector<string> > in get_all_values. It was considered
|
|
that if support for position-dependent options is to be
|
|
added, then we're be mostly interested in occurrences of
|
|
a single option that were before some point. That's possible
|
|
with vector<vector<string> > storage.
