Detailed Description

Member Function Documentation

◆ close()

ProfilerStub::close ( )

Close opened profiling sections.

Reimplemented from Profiler.

Definition at line 39 of file ProfilerStub.php.

◆ getFunctionStats()

ProfilerStub::getFunctionStats ( )

Get the aggregated inclusive profiling data for each method.

The percent time for each time is based on the current "total" time used is based on all methods so far. This method can therefore be called several times in between several profiling calls without the delays in usage of the profiler skewing the results. A "-total" entry is always included in the results.

When a call chain involves a method invoked within itself, any entries for the cyclic invocation should be be demarked with "@". This makes filtering them out easier and follows the xhprof style.

Returns
array[] List of method entries arrays, each having:
  • name : method name
  • calls : the number of invoking calls
  • real : real time elapsed (ms)
  • real : percent real time
  • cpu : CPU time elapsed (ms)
  • cpu : percent CPU time
  • memory : memory used (bytes)
  • memory : percent memory used
  • min_real : min real time in a call (ms)
  • max_real : max real time in a call (ms)
Since
1.25

◆ getOutput()

ProfilerStub::getOutput ( )

Returns a profiling output to be stored in debug file.

Returns
string

Reimplemented from Profiler.

Definition at line 35 of file ProfilerStub.php.

◆ logData()

ProfilerStub::logData ( )

Log the data to the backing store for all ProfilerOutput instances that have one.

Since

Reimplemented from Profiler.

Definition at line 42 of file ProfilerStub.php.

◆ logDataPageOutputOnly()

ProfilerStub::logDataPageOutputOnly ( )

Log the data to the script/request output for all ProfilerOutput instances that do so.

Exceptions
MWException
Since

Reimplemented from Profiler.

Definition at line 45 of file ProfilerStub.php.

◆ scopedProfileIn()

ProfilerStub::scopedProfileIn (   $section)
