// 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. This type having recognised its argument name just consumes
|
|
// that argument or option (ignores it). This is the so the validation
|
|
// process can then ask if all arguments or options have been recognised
|
|
// other an error will occurred "argument not recognised". For example
|
|
// this can be used to consume the "--" text which is not an argument in
|
|
// itself. Normally the GetValue() function (in base class) would return
|
|
// a value for the argument but is not the case for *this argument type
|
|
// object.
|
|
// Based on the Interpreter pattern.
