| 57 | Profile class. It is a "friend" of that class, and imports data either |

Tim Peters | 2344fae | 2001-01-15 00:50:52 +0000 | [diff] [blame] | 61 | The big change from the previous Profiler (in terms of raw functionality) |
| 62 | is that an "add()" method has been provided to combine Stats from |
| 63 | several distinct profile runs. Both the constructor and the add() |
| 64 | method now take arbitrarily many file names as arguments. |
Guido van Rossum | 54f22ed | 2000-02-04 15:10:34 +0000 | [diff] [blame] | 65 | |
Tim Peters | 2344fae | 2001-01-15 00:50:52 +0000 | [diff] [blame] | 66 | All the print methods now take an argument that indicates how many lines |
| 67 | to print. If the arg is a floating point number between 0 and 1.0, then |
| 68 | it is taken as a decimal percentage of the available lines to be printed |
| 69 | (e.g., .1 means print 10% of all available lines). If it is an integer, |
| 70 | it is taken to mean the number of lines of data that you wish to have |
| 71 | printed. |

Tim Peters | 2344fae | 2001-01-15 00:50:52 +0000 | [diff] [blame] | 73 | The sort_stats() method now processes some additional options (i.e., in |
Matthias Bussonnier | 8fb1f6e | 2017-02-20 21:30:00 -0800 | [diff] [blame] | 74 | addition to the old -1, 0, 1, or 2 that are respectively interpreted as |
mwidjaja | 863b1e4 | 2018-01-25 20:49:56 -0800 | [diff] [blame] | 75 | 'stdname', 'calls', 'time', and 'cumulative'). It takes either an |
| 76 | arbitrary number of quoted strings or SortKey enum to select the sort |
| 77 | order. |
Matthias Bussonnier | 8fb1f6e | 2017-02-20 21:30:00 -0800 | [diff] [blame] | 78 | |
mwidjaja | 863b1e4 | 2018-01-25 20:49:56 -0800 | [diff] [blame] | 79 | For example sort_stats('time', 'name') or sort_stats(SortKey.TIME, |
| 80 | SortKey.NAME) sorts on the major key of 'internal function time', and on |
| 81 | the minor key of 'the name of the function'. Look at the two tables in |
| 82 | sort_stats() and get_sort_arg_defs(self) for more examples. |
