Concrete subclasses must define an __init__() that defines self.graph and then calls the __init__() defined in this class. The concrete class must also define the class attributes NameFinder, FunctionGen, and ClassGen. These attributes can be defined in the initClass() method, which is a hook for initializing these methods after all the classes have been defined. i c C s | j d k r( | j � d | j _ n | j � t j � | _ t j � | _ d | _ | j � d | _ | j � j } x� | D]� } | d k r� | j j t � d | _ q� | d k r� | j j t � q� | d k r� | j j t � q� | d k r� | j j t � q� q� Wd S( Ni t BINARY_DIVIDEt divisiont BINARY_TRUE_DIVIDEt absolute_importt with_statementt print_function( t _CodeGenerator__initializedR/ t initClasst __class__t checkClassR t Stackt localst setupst last_linenot _setupGraphDelegationt _div_opt get_modulet futurest grapht setFlagR R R R ( R; R� t feature( ( s* /usr/lib64/python2.7/compiler/pycodegen.pyR< � s( c C s d S( s) This method is called once for each classN( ( R; ( ( s* /usr/lib64/python2.7/compiler/pycodegen.pyRv � t c C s7 y Wn, t k r2 } d | j j } t | � n Xd S( s* Verify that class is constructed correctlys Bad class construction for %sN( t AssertionErrorRw RB ( R; t msgt intro( ( s* /usr/lib64/python2.7/compiler/pycodegen.pyRx � s c C sO | j j | _ | j j | _ | j j | _ | j j | _ | j j | _ d S( N( R� t emitt newBlockt startBlockt nextBlockt setDocstring( R; ( ( s* /usr/lib64/python2.7/compiler/pycodegen.pyR} � s c C s | j j � S( s Return a code object( R� RA ( R; ( ( s* /usr/lib64/python2.7/compiler/pycodegen.pyRA � s c C s* | j d k r" t j | | j � S| Sd S( N( t class_nameR/ R t mangle( R; RY ( ( s* /usr/lib64/python2.7/compiler/pycodegen.pyR� � s c C s t j � } t | | � | j S( N( R t SymbolVisitorR t scopes( R; R? t s( ( s* /usr/lib64/python2.7/compiler/pycodegen.pyt parseSymbols s c C s t d � d S( Ns# should be implemented by subclasses( R0 ( R; ( ( s* /usr/lib64/python2.7/compiler/pycodegen.pyR s c C s | j j � j | � S( N( Rz t topR[ ( R; RY ( ( s* /usr/lib64/python2.7/compiler/pycodegen.pyt isLocalName s c C s | j d | � d S( Nt STORE( t _nameOp( R; RY ( ( s* /usr/lib64/python2.7/compiler/pycodegen.pyt storeName s c C s | j d | � d S( Nt LOAD( R� ( R; RY ( ( s* /usr/lib64/python2.7/compiler/pycodegen.pyt loadName s c C s | j d | � d S( Nt DELETE( R� ( R; RY ( ( s* /usr/lib64/python2.7/compiler/pycodegen.pyt delName s c C s | j | � } | j j | � } | t k rd | j sM | j | d | � q | j | d | � n� | t k r� | j | d | � n� | t k r� | j s� | j | d | � q | j | d | � nB | t k s� | t k r� | j | d | � n t d | | f � d S( Nt _NAMEt _FASTt _GLOBALt _DEREFs unsupported scope for var %s: %d( R� t scopet check_nameR t optimizedR� R R R R R0 ( R; t prefixRY R� ( ( s* /usr/lib64/python2.7/compiler/pycodegen.pyR� s c C s8 | j r | j | d | � n | j | d | � d S( s� Emit name ops for names generated implicitly by for loops The interpreter generates names that start with a period or dollar sign.

In visitAugAssign, the left-hand expression node is visited twice. The first time the visit uses the normal method for that node . The second time the visit uses a different method that generates the appropriate code to perform the assignment. These delegator classes wrap the original AST nodes in order to support the variant visit methods. c C s | | _ d S( N( t obj( R; R� ( ( s* /usr/lib64/python2.7/compiler/pycodegen.pyR< � s c C s t | j | � S( N( R� R� ( R; t attr( ( s* /usr/lib64/python2.7/compiler/pycodegen.pyt __getattr__� s ( RB RC Ri R< R ( ( ( s* /usr/lib64/python2.7/compiler/pycodegen.pyR� � s t AugGetattrc B s e Z RS( ( RB RC ( ( ( s* /usr/lib64/python2.7/compiler/pycodegen.pyR � s t AugNamec B s e Z RS( ( RB RC ( ( ( s* /usr/lib64/python2.7/compiler/pycodegen.pyR � s t AugSlicec B s e Z RS( ( RB RC ( ( ( s* /usr/lib64/python2.7/compiler/pycodegen.pyR s t AugSubscriptc B s e Z RS( ( RB RC ( ( ( s* /usr/lib64/python2.7/compiler/pycodegen.pyR s c C s t | j | � S( N( t wrapperRw ( R_ ( ( s* /usr/lib64/python2.7/compiler/pycodegen.pyRg s t __main__(M RR RK RJ RN t syst cStringIOR t compilerR R R R R R R R t compiler.constsR R R R R R R R R R R R R R t compiler.pyassemR t version_infoRF t AttributeErrorR� R� R� R� R� R+ R/ R# R: R2 R1 R" RT Rm Rn R� RF RD RE R� R� R R� R� R� R_ R� R� R R R R t Getattrt Namet Slicet SubscriptR Rg RB t argvt file( ( ( s* /usr/lib64/python2.7/compiler/pycodegen.pyt <module> s� ""(@ + � � � � U>
