Interface ProfilerAsync

public interface ProfilerAsync

  • Method Details

    • disable

      CompletableFuture<Void> disable()

    • enable

      CompletableFuture<Void> enable()

    • getBestEffortCoverage

      CompletableFuture<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

      CompletableFuture<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

      CompletableFuture<Void> start()

    • startPreciseCoverage

      CompletableFuture<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.
      Returns:
      Monotonically increasing time (in seconds) when the coverage update was taken in the backend.

    • startPreciseCoverage

      CompletableFuture<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
      Returns:
      Monotonically increasing time (in seconds) when the coverage update was taken in the backend.

    • startTypeProfile

      CompletableFuture<Void> startTypeProfile()
      Enable type profile.

    • stop

      CompletableFuture<Profile> stop()

    • stopPreciseCoverage

      CompletableFuture<Void> stopPreciseCoverage()
      Disable precise code coverage. Disabling releases unnecessary execution count records and allows executing optimized code.

    • stopTypeProfile

      CompletableFuture<Void> stopTypeProfile()
      Disable type profile. Disabling releases type profile data collected so far.

    • takePreciseCoverage

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

    • takeTypeProfile

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