    This is similar to urllib.urlencode except that:

    * It uses quote, and not quote_plus
    * It has a default list of safe chars that don't need
      to be encoded, which matches what AWS services expect.

    If any value in the input ``mapping`` is a list type,
    then each list element wil be serialized.  This is the equivalent
    to ``urlencode``'s ``doseq=True`` argument.

    This function should be preferred over the stdlib
    ``urlencode()`` function.

    :param mapping: Either a dict to urlencode or a list of
        ``(key, value)`` pairs.

    text type, will produce the binary type by UTF-8 encoding the

    will always return a datetime.datetime object with time zone
    information.

    The input param ``value`` can be one of several types:

        * A datetime object (both naive and aware)
        * An integer representing the epoch time (can also be a string
          of the integer, i.e '0', instead of 0).  The epoch time is
          considered to be UTC.
        * An iso8601 formatted timestamp.  This does not need to be
          a complete timestamp, it can contain just the date portion
          without the time component.

    The returned value will be a datetime object that will have tzinfo.
    If no timezone info was provided in the input value, then UTC is
    assumed, not local time.

�Zdd�Z	dS)�ArgumentGeneratoraGenerate sample input based on a shape model.

    This class contains a ``generate_skeleton`` method that will take
    an input/output shape (created from ``botocore.model``) and generate
    a sample dictionary corresponding to the input/output shape.

    The specific values used are place holder values. For strings either an
    empty string or the member name can be used, for numbers 0 or 0.0 is used.
    The intended usage of this class is to generate the *shape* of the input
    structure.

    This can be useful for operations that have complex input shapes.
    This allows a user to just fill in the necessary data instead of
    worrying about the specific structure of the input arguments.

    Example usage::

        s = botocore.session.get_session()
        ddb = s.get_service_model('dynamodb')
        arg_gen = ArgumentGenerator()
        sample_input = arg_gen.generate_skeleton(
            ddb.operation_model('CreateTable').input_shape)
        print("Sample input for dynamodb.CreateTable: %s" % sample_input)

    Check to see if the ``bucket_name`` complies with the
    restricted DNS naming conventions necessary to allow
    access via virtual-hosting style.

    Even though "." characters are perfectly valid in this DNS
    naming scheme, we are going to punt on any name containing a
    "." character because these will cause SSL cert validation
    problems if we try to use virtual-hosting style addressing.

    This handler looks at S3 requests just before they are signed.
    If there is a bucket name on the path (true for everything except
    ListAllBuckets) it checks to see if that bucket name conforms to
    the DNS naming conventions.  If it does, it alters the request to
    use ``virtual hosting`` style addressing rather than ``path-style``
    addressing.

    **This is not a general purpose caching decorator.**

    In order to use this, you *must* provide an ``_instance_cache``
    attribute on the instance.

    This decorator is used to cache method calls.  The cache is only
    scoped to a single instance though such that multiple instances
    will maintain their own cache.  In order to keep things simple,
    this decorator requires that you provide an ``_instance_cache``
