It is a "friend" of that class, and imports data either by direct access to members of Profile class, or by reading in a dictionary that was emitted (via marshal) from the Profile class. The big change from the previous Profiler (in terms of raw functionality) is that an "add()" method has been provided to combine Stats from several distinct profile runs. Both the constructor and the add() method now take arbitrarily many file names as arguments. All the print methods now take an argument that indicates how many lines to print. If the arg is a floating point number between 0 and 1.0, then it is taken as a decimal percentage of the available lines to be printed (e.g., .1 means print 10% of all available lines). If it is an integer, it is taken to mean the number of lines of data that you wish to have printed. The sort_stats() method now processes some additional options (i.e., in addition to the old -1, 0, 1, or 2). It takes an arbitrary number of quoted strings to select the sort order. For example sort_stats('time', 'name') sorts on the major key of 'internal function time', and on the minor key of 'the name of the function'. Look at the two tables in sort_stats() and get_sort_arg_defs(self) for more examples. All methods return self, so you can string together commands like: Stats('foo', 'goo').strip_dirs().sort_stats('calls'). print_stats(5).print_callers(5) streamNcGs_|p tj|_t|s'd}n|d}|dd}|j||j|dS)Nr)sysstdoutrleninitadd)selfrargsargr+/opt/alt/python34/lib64/python3.4/pstats.py__init__>s    zStats.__init__c Csd|_g|_d|_d|_d|_d|_d|_t|_i|_ i|_ |j |y|j WnBt k rtd|jr|jdndd|jYnXdS)NrzInvalid timing data %srfile) all_calleesfilesfcn_listtotal_tt total_calls prim_calls max_name_lenset top_levelstats sort_arg_dict load_statsget_top_level_stats Exceptionprintr)r r rrrr Hs"            'z Stats.initcCs|dkri|_dSt|trt|d}tj||_WdQXy-tj|}tj |j d|}WnYnX|g|_ n1t |dr|j |j|_i|_n|jstd|j|fndS)Nrbz create_statsz.Cannot create or construct a %r object from %r)r isinstancestropenmarshalloadosstattimeZctimest_mtimerhasattrr$ TypeError __class__)r r fZ file_statsrrrr[s(      zStats.load_statscCsx|jjD]\}\}}}}}|j|7_|j|7_|j|7_d|krw|jj|ntt||j krtt||_ qqWdS)Njprofilerprofiler)r2rr3) ritemsrrrrr rfunc_std_stringr)r funcccncttctcallersrrrr qs+ zStats.get_top_level_statscGsL|s |Sx;t|D]-}t|t|krDt|}n|j|j7_|j|j7_|j|j7_|j|j7_x!|jD]}|jj|qW|j |j kr|j |_ nd|_ xg|j j D]V\}}||j kr|j |}nddddif}t |||j |rrr rrr)r ZoldstatsZnewstatsrr6r7r8r9r:r;ZnewfuncZ newcallersfunc2callerZold_topZnew_toprrr strip_dirss.
