Method Detail

disable

void disable()

enable

void enable()

getBestEffortCoverage

List<ScriptCoverage> getBestEffortCoverage()

Collect coverage data for the current isolate. The coverage data may be incomplete due to garbage collection.

setSamplingInterval

void setSamplingInterval(Integer interval)

Changes CPU profiler sampling interval. Must be called before CPU profiles recording started.

Parameters:

interval - New sampling interval in microseconds.

start

void start()

startPreciseCoverage

Double startPreciseCoverage()

Enable precise code coverage. Coverage data for JavaScript executed before enabling precise code coverage may be incomplete. Enabling prevents running optimized code and resets execution counters.

startPreciseCoverage

Double startPreciseCoverage(Boolean callCount,
                            Boolean detailed,
                            Boolean allowTriggeredUpdates)

Enable precise code coverage. Coverage data for JavaScript executed before enabling precise code coverage may be incomplete. Enabling prevents running optimized code and resets execution counters.

Parameters:

callCount - Collect accurate call counts beyond simple 'covered' or 'not covered'.

detailed - Collect block-based coverage.

allowTriggeredUpdates - Allow the backend to send updates on its own initiative

startTypeProfile

void startTypeProfile()

Enable type profile.

stop

Profile stop()

stopPreciseCoverage

void stopPreciseCoverage()

Disable precise code coverage. Disabling releases unnecessary execution count records and allows executing optimized code.

stopTypeProfile

void stopTypeProfile()

Disable type profile. Disabling releases type profile data collected so far.

takePreciseCoverage

TakePreciseCoverage takePreciseCoverage()

Collect coverage data for the current isolate, and resets execution counters. Precise code coverage needs to have started.

takeTypeProfile

List<ScriptTypeProfile> takeTypeProfile()

Collect type profile.

enableCounters

void enableCounters()

Enable counters collection.

disableCounters

void disableCounters()

Disable counters collection.

getCounters

List<CounterInfo> getCounters()

Retrieve counters.

enableRuntimeCallStats

void enableRuntimeCallStats()

Enable run time call stats collection.

disableRuntimeCallStats

void disableRuntimeCallStats()

Disable run time call stats collection.

getRuntimeCallStats

List<RuntimeCallCounterInfo> getRuntimeCallStats()

Retrieve run time call stats.

onConsoleProfileFinished

EventListener onConsoleProfileFinished(EventHandler<ConsoleProfileFinished> eventListener)

onConsoleProfileStarted

EventListener onConsoleProfileStarted(EventHandler<ConsoleProfileStarted> eventListener)

Sent when new profile recording is started using console.profile() call.

onPreciseCoverageDeltaUpdate

EventListener onPreciseCoverageDeltaUpdate(EventHandler<PreciseCoverageDeltaUpdate> eventListener)

Reports coverage delta since the last poll (either from an event like this, or from `takePreciseCoverage` for the current isolate. May only be sent if precise code coverage has been started. This event can be trigged by the embedder to, for example, trigger collection of coverage data immediatelly at a certain point in time.
