Definition at line 50 of file phase_core.h.

◆ InitLatencyHistogram() void CppBenchmark::PhaseCore::InitLatencyHistogram ( const std::tuple< int64_t, int64_t, int > & latency ) inlineprotectednoexcept

Initialize latency histogram for the current phase.

Parameters: latency - Latency histogram parameters

Definition at line 81 of file phase_core.h.

◆ MergeMetrics() [1/2] void CppBenchmark::PhaseCore::MergeMetrics ( ) inlineprotected

◆ ResetMetrics() void CppBenchmark::PhaseCore::ResetMetrics ( ) inlineprotectednoexcept ◆ ScopePhase() std::shared_ptr< PhaseScope > CppBenchmark::PhaseCore::ScopePhase ( const std::string & phase ) inlineoverridevirtual

Start a new sub-phase with a given name in a single-thread environment and wrap it in a PhaseScope.

Please note the method is not thread-safe and should not be called in multi-thread environment!

Parameters

Returns: Shared pointer to the required benchmark sub-phase scope wrapper

Implements CppBenchmark::Phase.

Definition at line 58 of file phase_core.h.

◆ ScopePhaseThreadSafe() std::shared_ptr< PhaseScope > CppBenchmark::PhaseCore::ScopePhaseThreadSafe ( const std::string & phase ) inlineoverridevirtual

Start a new sub-phase with a given name in a multi-thread environment and wrap it in a PhaseScope.

Please note the method is thread-safe and might be called in multi-thread environment!

Parameters

Returns: Shared pointer to the required thread-safe benchmark sub-phase scope wrapper

Implements CppBenchmark::Phase.

Definition at line 60 of file phase_core.h.

◆ StartCollectingMetrics() void CppBenchmark::PhaseCore::StartCollectingMetrics ( ) inlineprotectednoexcept

Start collecting metrics in the current phase.

Definition at line 92 of file phase_core.h.

◆ StartPhase() std::shared_ptr< Phase > CppBenchmark::PhaseCore::StartPhase ( const std::string & phase ) overridevirtual

Start a new sub-phase with a given name in a single-thread environment.

This method will create or get existent sub-phase with a given name, start benchmark measurement and return it as a shared pointer. Please note the method is not thread-safe and should not be called in multi-thread environment!

Parameters

Returns: Shared pointer to the required benchmark sub-phase

Implements CppBenchmark::Phase.

Definition at line 15 of file phase_core.cpp.

◆ StartPhaseThreadSafe() std::shared_ptr< Phase > CppBenchmark::PhaseCore::StartPhaseThreadSafe ( const std::string & phase ) overridevirtual

Start a new sub-phase with a given name in a multi-thread environment.

This method will create or get existent sub-phase with a given name, start benchmark measurement and return it as a shared pointer. Please note the method is thread-safe and might be called in multi-thread environment!

Parameters

Returns: Shared pointer to the thread safe benchmark sub-phase

Implements CppBenchmark::Phase.

Definition at line 38 of file phase_core.cpp.

◆ StopCollectingMetrics() void CppBenchmark::PhaseCore::StopCollectingMetrics ( ) inlineprotectednoexcept

Stop collecting metrics in the current phase.

Definition at line 95 of file phase_core.h.
