The class is used for reading command arguments.
Supports the following syntax:
//-k=10 --x 0.001 --inputFile lena.jpg
int k = parser.get<int>("--k | -k", -1);
double x = parser.get<double>("--x");
string inputFile = parser.get<string>("--inputFile");
//-k=10 --key --db=-10.11 -key1 argument --inputFile=lena.jpg
CommandLineParser parser(argc, argv);
int k = parser.get<int>("k", -1); //these methods also work
double db = parser.get<double>("db"); //with <float> and <unsigned int> type
string key = parser.get<string>("0");
string key1 = parser.get<string>("1");
string argument = parser.get<string>("2");
string inputFile = parser.get<string>("inputFile");
If parameter must to have some value, you have to define it using '--' or '-' increment
and assign is a value through '='. For example like this: --key=120 or -file_name=lena.jpg
If parameter doesn't has any value, you can define it with '--' or '-' increment and without it.
In this case you have to select it index in command line, if you whant to get it.
Only keys without any value have it personal index.Index starts from zero.
For example, see the string with arguments above: --key has index 0, -key has index 1, argument has index 2
other keys have some values and they don't have index.
