How do I know whether the value found using getOptionValue was given by the user and is not the default value?

All I have in my arsenal is the commandContext and it doesn't help much with my use-case. Other than that, I can retrieve the rawArgs but I failed to reverse-engineer the code of the parser. It seems to use various constructor arguments I have no idea where they come from.

I can figure out if getOptionValue is the same as defaultValue, but there's a chance the user entered the same as the default value, as well. How do I know?

Consider the following (command foo has option -b has default value of bar):

shell:> foo -b bar
shell:> foo -b
shell:> foo

The first command will give the value bar, the second will give the value null, while the third will also give the value bar.

I have no idea whether the user has given -b or not, using the commandContext.
