Placing option values into an object or collection

[reganvJohnson]

I'm very new to picocli, and like what I see, but I'm curious about how people manage multiple command line options.
for example, this is a very simple example:

@Option(names = {"-f", "--file"}, required = true, description = "Name of the to be processed")
private String fileName;
@Option(names = {"-p", "--pattern"}, required = true, description = "regex pattern to process")
private String pattern;
@Option(names = {"-a", "--algorithm"}, required = true, description = "crypto algorithm used for encryption")
private String cryptoAlgorithm;
@Option(names = {"-l", "--flag"}, description = "some sort of boolean flag")
private Boolean theFlag;

now, I have four member variables to worry about. I was wondering if there was a way to automatically instantiate, or stuff them into an object/record or collection, so that they can be passed around easily. I'm doing this by hand right now, and that works, but is there a way to do this automatically? I'm guessing that this would be especially annoying if I was building something like curl, with a kazillion options.

Maybe something like this...

@Option(names = {"-f", "--file"}, required = true, key="file", description = "Name of the to be processed")
@Option(names = {"-p", "--pattern"}, required = true, key="regexPattern", description = "regex pattern to process")
@Option(names = {"-a", "--algorithm"}, required = true, key="algorithm" description = "crypto algorithm used for encryption")
@Option(names = {"-l", "--flag"}, description = "some sort of boolean flag", key="flag")
private HashMap<String, Object> options;

then I access any value like:
options.get("regexPattern");

Thanks in advance!

In my own applications, when I need an object that has (some of the) options without the rest of the logic of that command, I put those options in a separate class. Then in my command I include those options with the @Mixin annotation, and I can pass that object around to other parts of the application that need the option values but don't need to know about the rest of the command.

WOW! That looks exactly like what I want. Thanks! I was hoping to use a record object, because records are 'sexy' and I've never used one before, but that may not work, and a POJO is more useful. I can see a fun morning of exploration coming up!
