Method Detail

disable

public static Command<java.lang.Void> disable()

Disable Profiling

enable

public static Command<java.lang.Void> enable()

Enable Profiling

start

public static Command<java.lang.Void> start()

start Profiling process

stop

public static Command<Profile> stop()

stop Profiling process

getBestEffortCoverage

public static Command<java.util.List<ScriptCoverage>> getBestEffortCoverage()

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

setSamplingInterval

public static Command<java.lang.Void> setSamplingInterval(int interval)

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

Parameters:

interval - New sampling interval in microseconds.

startPreciseCoverage

public static Command<java.lang.Void> startPreciseCoverage(java.util.Optional<java.lang.Boolean> callCount,
                                                           java.util.Optional<java.lang.Boolean> detailed)

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.

startTypeProfile

@Beta
public static Command<java.lang.Void> startTypeProfile()

Enable type profile

stopPreciseCoverage

public static Command<java.lang.Void> stopPreciseCoverage()

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

stopTypeProfile

@Beta
public static Command<java.lang.Void> stopTypeProfile()

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

takePreciseCoverage

public static Command<java.util.List<ScriptCoverage>> takePreciseCoverage()

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

takeTypeProfile

@Beta
public static Command<java.util.List<ScriptCoverage>> takeTypeProfile()

Collect type profile.EXPERIMENTAL

consoleProfileFinished

public static Event<ConsoleProfileFinished> consoleProfileFinished()

consoleProfileStarted

public static Event<ConsoleProfileStarted> consoleProfileStarted()

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