Interface Profiler

  • public interface Profiler

    • 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.
        Returns:
        Coverage data for the current isolate.

      • 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

        void startPreciseCoverage​(Boolean callCount,
                          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

        void startTypeProfile()
        Enable type profile.

      • 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

        List<ScriptCoverage> takePreciseCoverage()
        Collect coverage data for the current isolate, and resets execution counters. Precise code coverage needs to have started.
        Returns:
        Coverage data for the current isolate.

      • takeTypeProfile

        List<ScriptTypeProfile> takeTypeProfile()
        Collect type profile.
        Returns:
        Type profile for all scripts since startTypeProfile() was turned on.

      • startPreciseCoverage

        void 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.
