Unlike regular clones, this clone also mimics __hash__() and __cmp__() of the original element so that it takes its place in hashed collections. A reference to the original element is maintained, for the important reason of keeping its hash value current. When GC'ed, the hash value may be reused, causing conflicts. cGsg|stj|ƒS|\}}yt|j}Wn#tk rUt|j|ƒ}nXtj|ƒSdS(N(tobjectt__new__tannotated_classest __class__tKeyErrort_new_annotation_type(tclstargstelementtvalues((s_/var/www/send.findwatt.com/datamanager/lib/python2.7/site-packages/sqlalchemy/sql/annotation.pyRs   cCs(|jjƒ|_||_||_dS(N(t__dict__tcopyt_Annotated__elementt _annotations(tselfR R ((s_/var/www/send.findwatt.com/datamanager/lib/python2.7/site-packages/sqlalchemy/sql/annotation.pyt__init__-s cCs)|jjƒ}|j|ƒ|j|ƒS(N(RRtupdatet_with_annotations(RR t_values((s_/var/www/send.findwatt.com/datamanager/lib/python2.7/site-packages/sqlalchemy/sql/annotation.pyt _annotate2s cCs4|jj|jƒ}|jjƒ|_||_|S(N(RRR RR(RR tclone((s_/var/www/send.findwatt.com/datamanager/lib/python2.7/site-packages/sqlalchemy/sql/annotation.pyR7s cCsT|dkr|jS|jjƒ}x|D]}|j|dƒq)W|j|ƒSdS(N(tNoneRRRtpopR(RR RRtv((s_/var/www/send.findwatt.com/datamanager/lib/python2.7/site-packages/sqlalchemy/sql/annotation.pyt _deannotate=s   cKs|jjj|||S(N(RRt_compiler_dispatch(Rtvisitortkw((s_/var/www/send.findwatt.com/datamanager/lib/python2.7/site-packages/sqlalchemy/sql/annotation.pyRFs cCs |jjS(N(Rt _constructor(R((s_/var/www/send.findwatt.com/datamanager/lib/python2.7/site-packages/sqlalchemy/sql/annotation.pyRJscCsL|jjƒ}||jkr"|S|jj|jƒ|j||jƒSdS(N(Rt_cloneR RRR(RR((s_/var/www/send.findwatt.com/datamanager/lib/python2.7/site-packages/sqlalchemy/sql/annotation.pyR Ns cCs t|jƒS(N(thashR(R((s_/var/www/send.findwatt.com/datamanager/lib/python2.7/site-packages/sqlalchemy/sql/annotation.pyt__hash__YscCsEt|jtjƒr+|jjj||ƒSt|ƒt|ƒkSdS(N(t isinstanceRRtColumnOperatorsRt__eq__R!(Rtother((s_/var/www/send.findwatt.com/datamanager/lib/python2.7/site-packages/sqlalchemy/sql/annotation.pyR%\sN(t__name__t __module__t__doc__RRRRRtTrueRRtpropertyRR R"R%(((s_/var/www/send.findwatt.com/datamanager/lib/python2.7/site-packages/sqlalchemy/sql/annotation.pyRs       cs4‡‡‡fd†‰|dk r0ˆ|ƒ}n|S(sΉDeep copy the given ClauseElement, annotating each element with the given annotations dictionary.
