Checks if the input can be handled by this class. If it cannot handle the input, rejects with an error explaining why.
Input that could potentially be handled.
A promise resolving if the input can be handled, rejecting with an Error if not.
Handles the given input. This may only be called if canHandle did not reject. When unconditionally calling both in sequence, consider handleSafe instead.
Input that needs to be handled.
A promise resolving when handling is finished.
Input data that will be handled if it can be handled.
A promise resolving if the input can be handled, rejecting with an Error if not.
Converts the input CLI arguments into an easily parseable key/value object.
