Detailed Description

Profiler base class that defines the interface and some trivial functionality.

Constructor & Destructor Documentation

Profiler::__construct ( array $params )

Parameters

array $params

Definition at line 50 of file Profiler.php.

References $params.

Member Function Documentation

Profiler::close ( )

abstract

Close opened profiling sections.

Profiler::getContentType ( )

Get the content type sent out to the client.

Used for profilers that output instead of store data.

Returns: string

Since: 1.25

Definition at line 259 of file Profiler.php.

References $header, and as.

Profiler::getContext ( )

Gets the context for this Profiler.

Returns: IContextSource

Since: 1.25

Definition at line 139 of file Profiler.php.

References $context, RequestContext\getMain(), and wfDebug().

Referenced by logData().

Profiler::getFunctionStats ( )

abstract

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

Returns: string

Profiler::getOutputs ( )

Get all usable outputs.

Exceptions

MWException

Returns: array Array of ProfilerOutput instances.
