| 42 | class Stats: |
| 43 | """This class is used for creating reports from data generated by the |
| 44 | Profile class. It is a "friend" of that class, and imports data either |
| 45 | by direct access to members of Profile class, or by reading in a dictionary |
| 46 | that was emitted (via marshal) from the Profile class. |
| 47 | |
| 48 | The big change from the previous Profiler (in terms of raw functionality) |
| 49 | is that an "add()" method has been provided to combine Stats from |
| 50 | several distinct profile runs. Both the constructor and the add() |
| 51 | method now take arbitrarily many file names as arguments. |
| 52 | |
| 53 | All the print methods now take an argument that indicates how many lines |
| 54 | to print. If the arg is a floating point number between 0 and 1.0, then |
| 55 | it is taken as a decimal percentage of the available lines to be printed |
| 56 | (e.g., .1 means print 10% of all available lines). If it is an integer, |
| 57 | it is taken to mean the number of lines of data that you wish to have |
| 58 | printed. |
| 59 | |
| 60 | The sort_stats() method now processes some additional options (i.e., in |
| 61 | addition to the old -1, 0, 1, or 2). It takes an arbitrary number of quoted |
| 62 | strings to select the sort order. For example sort_stats('time', 'name') |
| 63 | sorts on the major key of "internal function time", and on the minor |
| 64 | key of 'the name of the function'. Look at the two tables in sort_stats() |
| 65 | and get_sort_arg_defs(self) for more examples. |
| 66 | |
| 67 | All methods now return "self", so you can string together commands like: |
| 68 | Stats('foo', 'goo').strip_dirs().sort_stats('calls').\ |
| 69 | print_stats(5).print_callers(5) |
