Does the Poco C++ Library Support positional command line arguments?

Question

I can see no way to support positional command line arguments with Poco's Poco::Util::Application class and related Poco::Util::OptionProcessor . Positional arguments are unnamed arguments on the command line, coming at the end after all other options, as such:

someprogram -b --what=121 filename.bin

In that example, filename.bin is a positional argument, it has no name, but is the first positional argument after all named arguments. Boost's program_options supports this, and I find it hard to believe Poco does not, but I can't discover how to support it given the source and documentation.

Does Poco support this?

我对Poco不熟悉，但是在查看文档时，我怀疑预期的用法是在argv连续元素上重复调用Poco::Util::OptionProcessor::process() ，直到返回false ，然后表示位置参数的开始，让您随心所欲地处理它们。
