◆ GetSampleCount()

MAXON_METHOD UInt32 GetSampleCount ( )

Gets the count of captured samples.

Returns
Captured sample count.

◆ Reset()

MAXON_METHOD void Reset ( )

Resets the profiler.

◆ GetDebugDumpEnabled()

MAXON_METHOD Bool GetDebugDumpEnabled ( )

Gets the profiler debug dump enabled state.

Returns
True if enabled, false otherwise.

◆ SetDebugDumpEnabled()

MAXON_METHOD void SetDebugDumpEnabled ( Bool  state)

Sets the profiler debug dump enabled state.

Parameters
[in]stateTrue if enabled, false otherwise.

◆ GetEnableState() [1/2]

MAXON_METHOD PROFILER_STATE GetEnableState ( )

Gets the profiler state.

Returns
State: DISABLED, ENABLED_METHOD_SCOPE, ENABLED_ALL

◆ SetEnableState()

MAXON_METHOD void SetEnableState ( PROFILER_STATE  state)

Sets the profiler state.

Parameters
[in]stateState: DISABLED, ENABLED_METHOD_SCOPE, ENABLED_ALL

◆ GetEnableState() [2/2]

MAXON_METHOD Bool GetEnableState ( const ProfilingPoint &  profilingPoint)

Gets the enabled state of a profiling point.

Returns
True if enabled.

◆ GetMacroTime()

MAXON_METHOD void GetMacroTime ( )

Gets the current time. Used by the calling macro to capture the time before arguments for the call to AddPointSample or AddSample methods are evaluated.

◆ IsFirstTime()

MAXON_METHOD Bool IsFirstTime ( const ProfilingPoint &  profilingPoint)

Indicates if a profiling point is visited for the first time in the current scope.

Parameters
[in]profilingPointProfilingPoint reference.
Returns
True or false.

◆ AddSample()

MAXON_METHOD void AddSample ( const ProfilingPoint &  profilingPoint)

Adds a sample to a profiling point in the current scope.

A profiling point may be visited multiple times during execution, e.g. within a loop. Every encounter records a time measurement sample, which is added to the scope point, and is used to calculate the total and average time for all captured samples. Points of METHOD_ENTER or SCOPE_ENTER types capture the total scope time for every sample, allowing to report the average scope time as well.

Parameters
[in]profilingPointProfilingPoint reference.

◆ AddPointSample() [1/2]

MAXON_METHOD void AddPointSample ( const ProfilingPoint &  profilingPoint,
const Char *  outputString = nullptr 
)

Adds a profiling point to the current scope and registers a sample.

A profiling point is declared by using a PROFILER macro with an optional output string to be printed with the trace report. If present, the string is recorded the first time a profiling point is visited per scope.

The following example gets the global profiler, configures it to use a simulated clock (to force the captured time values to be constant) and defines profiling points to run the following sequence:

ME 5ms SE loop5x{ 10ms D } 5ms SL ML

where:

  • ME = METHOD_ENTER
  • #ms = time delta in milliseconds
  • SE = SCOPE_ENTER
  • D = DELTA
  • SL = SCOPE_LEAVE
  • ML = METHOD_LEAVE
