This class offers almost the same behaviour as Python's super, which is MRO lookups for retrieving attributes from the parents. The *mro_pointer* is the place in the MRO from where we should start looking, not counting it. *mro_type* is the object which provides the MRO, it can be both a type or an instance. *self_class* is the class where the super call is, while *scope* is the function where the super call is. cCs tjƒS(N(t objectmodelt SuperModel(((s.lib/python2.7/site-packages/astroid/objects.pyt<scCs1||_||_t|_||_||_dS(N(ttypet mro_pointertFalset _class_basedt _self_classt_scope(R Rtmro_typet self_classtscope((s.lib/python2.7/site-packages/astroid/objects.pyt__init__?s     ccs |VdS(N((R R ((s.lib/python2.7/site-packages/astroid/objects.pyR FscCst|jtjƒs-tjdd|ƒ‚nt|jtjƒrWt|_|j}nHt |jddƒ}t|t j tjfƒsŸtjdd|ƒ‚n|j sÀtjdd|ƒ‚n|jƒ}|j|krótjdd|ƒ‚n|j|jƒ}||dS(sBGet the MRO which will be used to lookup attributes in this super.sIThe first argument to super must be a subtype of type, not {mro_pointer}.tsuper_RsPThe second argument to super must be an instance or subtype of type, not {type}.s*Unable to call super on old-style classes.iN(t isinstanceRRtClassDefRt SuperErrorRtTrueRRRRtInstancetnewstyletmrotindex(R R!R,R-((s.lib/python2.7/site-packages/astroid/objects.pyt super_mroIs*       cCstjt}|jdƒdS(Ntsuperi(RRRR(R R((s.lib/python2.7/site-packages/astroid/objects.pyRis cCsdtS(Ns%s.super(R(R ((s.lib/python2.7/site-packages/astroid/objects.pyR nscCsdS(NsSuper of((R ((s.lib/python2.7/site-packages/astroid/objects.pyt display_typeqscCs |jjS(s Get the name of the MRO pointer.(Rtname(R ((s.lib/python2.7/site-packages/astroid/objects.pyR1tsc cs"||jkr$|jj|ƒVdSy|jƒ}Wn–tjk r}}tjtjdd|d|d|d|jƒƒnPtj k rÌ}tjtjdd|d|d|d|j d |j ƒƒnXt }x!|D]}||j krõqÚnt}xõtj||g|d |ƒD]Ô}t|tjƒs>|Vqn|jd kratj||ƒVq|jjd krŠ|jd krŠ|Vq|js¢|jd krª|Vqtj|ƒrÞx3|j||ƒD] }|VqÌWqtj||ƒVqWqÚW|stjd|d|d|ƒ‚ndS(s9Retrieve the inferred values of the given attribute name.NsHLookup for {name} on {target!r} because super call {super!r} is invalid.ttargett attributeR R%sJLookup for {name} on {target!r} failed because {cls!r} has an invalid MRO.tmrostclstframet classmethodtmethodt staticmethod(tspecial_attributestlookupR.RR(RtreraisetAttributeInferenceErrorR%tMroErrorR4R5RtlocalsR)Rt _infer_stmtsR&Rt FunctionDefRt BoundMethodR Rt _is_propertytinfer_call_result( R R1R R,texctfoundR5tinferredtvalue((s.lib/python2.7/site-packages/astroid/objects.pytigetattrysJ "  &! cCst|j|d|ƒƒS(NR (tlistRI(R R1R ((s.lib/python2.7/site-packages/astroid/objects.pyR®sN(RRRRtlazy_descriptorR:R$RR R.RRRR R0tpropertyR1RIR(((s.lib/python2.7/site-packages/astroid/objects.pyR/s       5tExceptionInstancecBs eZdZejd„ƒZRS(sÐClass for instances of exceptions It has special treatment for some of the exceptions's attributes, which are transformed at runtime into certain concrete objects, such as the case of .args. cCs tjƒS(N(RtExceptionInstanceModel(((s.lib/python2.7/site-packages/astroid/objects.pyR»s(RRRRRKR:(((s.lib/python2.7/site-packages/astroid/objects.pyRM²st DictInstancecBs eZdZejd„ƒZRS(sÊSpecial kind of instances for dictionaries This instance knows the underlying object model of the dictionaries, which means that methods such as .values or .items can be properly inferred. cCs tjƒS(N(Rt DictModel(((s.lib/python2.7/site-packages/astroid/objects.pyRÆs(RRRRRKR:(((s.lib/python2.7/site-packages/astroid/objects.pyRO¾st DictItemscBs eZejjZejjZRS((RRRtNodeNGt__str__t__repr__(((s.lib/python2.7/site-packages/astroid/objects.pyRQÌs tDictKeyscBs eZejjZejjZRS((RRRRRRSRT(((s.lib/python2.7/site-packages/astroid/objects.pyRUÑs t DictValuescBs eZejjZejjZRS((RRRRRRSRT(((s.lib/python2.7/site-packages/astroid/objects.pyRVÖs (RtsixtastroidRRRRRRRtmovesRRRt lazy_importRt_BaseContainerRRRRR*RMROtProxyRQRURVtDictt __bases__(((s.lib/python2.7/site-packages/astroid/objects.pyts$ ƒ
