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()``. iÿÿÿÿNi(tDialecti(texc(tutil(tplugins(tregistrytURLcBs¼eZdZddddddd„Zed„Zd„Zd„Zd„Z d„Z d„Z e d„ƒZ e jd „ƒZ d „Zd „Zd „Zd „Zd„Zgd„ZRS(sX 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. cCsg||_||_||_||_|dk rBt|ƒ|_n d|_||_|p]i|_dS(N( t drivernametusernametpassword_originalthosttNonetinttporttdatabasetquery(tselfRRtpasswordR R R R((s4lib/python2.7/site-packages/sqlalchemy/engine/url.pyt__init__8s       csOˆjd}ˆjdk rq|tˆjƒ7}ˆjdk rd|d|rPdn tˆjƒ7}n|d7}nˆjdk r³dˆjkr£|dˆj7}q³|ˆj7}nˆjdk rÜ|dtˆjƒ7}nˆjdk rÿ|dˆj7}nˆj rKt ˆj ƒ}|j ƒ|ddj ‡fd †|Dƒƒ7}n|S( Ns://t:s***t@s[%s]t/t?t&c3s<|]2}tjˆj|ƒD]}d||fVqqdS(s%s=%sN(Rtto_listR(t.0tktelement(R(s4lib/python2.7/site-packages/sqlalchemy/engine/url.pys cs( RRR t_rfc_1738_quoteRR R tstrR Rtlisttsorttjoin(Rt hide_passwordtstkeys((Rs4lib/python2.7/site-packages/sqlalchemy/engine/url.pyt __to_string__Ms,       cCs|jdtƒS(NR (R#tFalse(R((s4lib/python2.7/site-packages/sqlalchemy/engine/url.pyt__str__iscCs |jƒS(N(R#(R((s4lib/python2.7/site-packages/sqlalchemy/engine/url.pyt__repr__lscCstt|ƒƒS(N(thashR(R((s4lib/python2.7/site-packages/sqlalchemy/engine/url.pyt__hash__oscCs‹t|tƒoŠ|j|jkoŠ|j|jkoŠ|j|jkoŠ|j|jkoŠ|j|jkoŠ|j|jkoŠ|j|jkS(N( t isinstanceRRRRR R RR (Rtother((s4lib/python2.7/site-packages/sqlalchemy/engine/url.pyt__eq__rscCs ||k S(N((RR*((s4lib/python2.7/site-packages/sqlalchemy/engine/url.pyt__ne__~scCs'|jdkrdStj|jƒSdS(N(RR Rt text_type(R((s4lib/python2.7/site-packages/sqlalchemy/engine/url.pyRscCs ||_dS(N(R(RR((s4lib/python2.7/site-packages/sqlalchemy/engine/url.pyRˆscCs.d|jkr|jS|jjdƒdSdS(Nt+i(Rtsplit(R((s4lib/python2.7/site-packages/sqlalchemy/engine/url.pytget_backend_nameŒscCs4d|jkr|jƒjS|jjdƒdSdS(NR.i(Rt get_dialecttdriverR/(R((s4lib/python2.7/site-packages/sqlalchemy/engine/url.pytget_driver_name’s cCs]tj|jjddƒƒ}||jdgƒ7}g|D]}tj|ƒ||ƒ^q;S(NtpluginR((RRRtgetRtload(Rtkwargst plugin_namest plugin_name((s4lib/python2.7/site-packages/sqlalchemy/engine/url.pyt_instantiate_plugins˜scCsd|jkr|j}n|jjddƒ}tj|ƒ}t|dƒryt|jtƒryt|jt ƒry|jS|SdS(sºReturn the "entry point" dialect class.
