Process

The process to execute the command looks something like this:

Configure model -> Build reflection model -> Parse arguments -> Binding -> Invocation

1. Configure model

In the configuration step, we let the consumer of the API specify the overall command structure.

2. Build reflection model

We then build a model that represents the commands and their options, argument and other settings such as description.

3. Parse arguments

The next step is to parse the arguments into a command tree while also verifying it to the model we built in the previous step.

Here we also create string mappings for options and arguments to the different commands but we don't bind anything to the settings object (which do not exist yet).

4. Binding

Now we can take the parsed command tree and it's assigned options and arguments and bind the values to an instance of the leaf settings class. If you've specified a specific type converter for a value, here is where it will be used.

5. Invocation

Now we can instantiate the command itself and execute it by passing the bound settings to it.
