 | |
|     """This class is used for creating reports from data generated by the
 | |
|     Profile class.  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)
