All Implemented Interfaces:

InvocationHandler

public class ArgumentParser
extends Object
implements InvocationHandler

Parser for command line arguments. The parser creates a dynamic proxy which can be access via a command line argument interface.

The command line argument proxy interface must follow these conventions:
- Methods do not define arguments
- Method names must start with get
- Allowed return types are Integer, Boolean and String

Note: Do not use this class, internal use only!
