|

"""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)
