This module handles user input parameter validation
against a provided input model.
Note that the objects in this module do *not* mutate any
arguments. No type version happens here. It is up to another
layer to properly convert arguments to any required types.
Validation Errors
-----------------
� )�sixN)�datetime)�parse_to_aware_datetime)�is_json_value_header)�ParamValidationErrorc C s, t � }|j| |�}|j� r(t|j� d��dS )av Validates input parameters against a schema.
This is a convenience function that validates parameters against a schema.
You can also instantiate and use the ParamValidator class directly if you
want more control.
If there are any validation errors then a ParamValidationError
will be raised. If there are no validation errors than no exception
is raised and a value of None is returned.
:param params: The user provided input parameters.
:type shape: botocore.model.Shape
:param shape: The schema which the input parameters should
adhere to.
:raise: ParamValidationError

This method will validate the parameters against a provided shape model.
All errors will be collected before returning to the caller. This means
that this method will not stop at the first error, it will return all
possible errors.
:param params: User provided dict of parameters
:param shape: A shape model describing the expected input.
:return: A list of errors.
