Construct an `Overloader`.

Parameters:

    `overloads` :: (Overload...)
        a collection of rules indicating which operation to call for
        which combination of arguments/parameters. Note: the order can
        effect which overload is matched as the first matching overload
        is used. Must specify at least one overload.

    `add_self` :: bool = True
        if True, a "self" parameter is inserted at the beginning of the
        parameter list of each overload

Overrides: object.__init__

process_call(self, args, kwargs)

source code


Process a call with given args and keyword args.

The matching overload is called.

Parameters:

    `args`, `kwargs'
        arguments of the call

Returns the return value of the called operation
