        public Profiler()

    • 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

      • 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

      • consoleProfileStarted

        public static Event<ConsoleProfileStarted> consoleProfileStarted()
        Sent when new profile recording is started using console.profile() call.
