Classes defined using this metaclass have an automatic tracing feature -- by setting the __trace_output__ instance (or class) variable to a file object, trace messages about all calls are written to the file. The trace formatting can be changed by defining a suitable __trace_call__ method. i c C s( | | _ | | _ | | _ d | _ d S( Ni ( t __name__t __bases__t _TraceMetaClass__dictt _TraceMetaClass__inited( t selft namet basest dict( ( s. /usr/lib64/python2.7/Demo/metaclasses/Trace.pyt __init__ s c C si y | j | SWnS t k rd x6 | j D]+ } y | j | � SWq) t k rS q) Xq) Wt | � n Xd S( N( R t KeyErrorR t __getattr__t AttributeError( R R t base( ( s. /usr/lib64/python2.7/Demo/metaclasses/Trace.pyR s c C s* | j s | | j | <n | | j | <d S( N( R t __dict__R ( R R t value( ( s. /usr/lib64/python2.7/Demo/metaclasses/Trace.pyt __setattr__( s c O sZ t � } | j | � y | j d � } Wn t k rE d � } n Xt | | | � | S( NR c S s d S( N( t None( ( ( s. /usr/lib64/python2.7/Demo/metaclasses/Trace.pyt <lambda>4 s ( t TracingInstancet __meta_init__R R t apply( R t argst kwt instt init( ( s. /usr/lib64/python2.7/Demo/metaclasses/Trace.pyt __call__. s N( R t __module__t __doc__R R R R R R t __trace_output__( ( ( s. /usr/lib64/python2.7/Demo/metaclasses/Trace.pyR s R c B s) e Z d Z d � Z d � Z d � Z RS( s9 Helper class to represent an instance of a tracing class.c G s | j | d | � d S( Ns ( t write( R t fpt fmtR ( ( s. /usr/lib64/python2.7/Demo/metaclasses/Trace.pyt __trace_call__= s c C s | | _ d S( N( t _TracingInstance__class( R t klass( ( s. /usr/lib64/python2.7/Demo/metaclasses/Trace.pyR @ s c C s� y | j j | � } Wn t k r2 t | � n Xt | � t j k rL | S| j j d | } | j sv | d k r� t | | | � St | | | � Sd S( Nt .R!
