The URL object is created automatically when :func:`~sqlalchemy.engine.create_engine` is called with a string argument; alternatively, the URL is a public-facing construct which can be used directly and is also accepted directly by ``create_engine()``. � N� )�Dialect� )�exc)�util)�plugins)�registryc @ s� e Zd ZdZ d!dd�Zd"dd�Zdd � Zd d � Zd d � Zdd� Z dd� Z e dd� �Z e j dd� �Z dd� Zdd� Zdd� Zdd � Zd d � Zg fd d �ZdS )#�URLaX Represent the components of a URL used to connect to a database. This object is suitable to be passed directly to a :func:`~sqlalchemy.create_engine` call. The fields of the URL are parsed from a string by the :func:`.make_url` function. the string format of the URL is an RFC-1738-style string. All initialization parameters are available as public attributes. :param drivername: the name of the database backend. This name will correspond to a module in sqlalchemy/databases or a third party plug-in. :param username: The user name. :param password: database password. :param host: The name of the host. :param port: The port number. :param database: The database name. :param query: A dictionary of options to be passed to the dialect and/or the DBAPI upon connect.
