Solve the following python programming problem given the following code:
def parse(parameters) : 
    "Decorator to parse parameters according to a set of criteria.

    This outer method is called to set up the decorator.

    Arguments:
        parameters: An array of parameter declarations tuples in the format:
        ('<param_name>', {'validate': [<ValidatorClass>,...], <options...>})

    Usage:

    @chassis.util.parameters.parse([
        ('email', {'validators': [validators.Email], 'required': True}),
        ('password', {'validators': [validators.Password], 'required': True})
       ])
    def post(self, email=None, password=None):
        # Render JSON for the provided parameters
        self.render_json({'email': email, 'password': password})
    " 
    @ decorators.include_original 
    def decorate(method) : 
        'Setup returns this decorator, which is called on the method.' 
        def call(self, * args) : 
            'This is called whenever the decorated method is invoked.' 
            kwargs = _parse_arguments (self, method, parameters) 
            return method (self, * args, ** kwargs) 
return call 
return parameters
