Details:
The logical operators supported by findobj() should parse as if they were part
of a logical equation. For example, the current implementation does not give
precedence of "-and" over "-or".
%!xtest
%! hf = figure ("visible", "off");
%! unwind_protect
%! ha = axes ();
%! plot (1:10);
%! h = findobj (hf, 'type', 'figure', ...
%! '-or', 'parent', 1, ...
%! '-and', 'type', 'axes')
%! unwind_protect_cleanup
%! close (hf)
%! end_unwind_protect
%! assert (h, [hf; ha])
-verabtim-
Is there a way to do this in c++ and make use of the parser to handle the
precedence?
I'll add the above xtest to findobj().
