| // Details: MI common code class. Command argument class. Arguments object |
| // needing specialization derived from the CMICmdArgValBase class. |
| // An argument knows what type of argument it is and how it is to |
| // interpret the options (context) string to find and validate a |
| // matching |
| // argument and so extract a value from it . |
| // The CMICmdArgValBase objects added to *this ListOfN container belong |
| // to this container and will be deleted when *this object goes out of |
| // scope. |
| // To parse arguments like 'thread-id ...' i.e. 1 10 12 13 ... |
| // If vbMandatory argument is true it takes on the (...)+ specification |
| // otherwise assumed to be (...)* specification. |
| // Based on the Interpreter pattern. |
