ProfilerModel

Remarks

Which source is selected, whether it is recording, what the last capture holds, and what it is being compared against — none of which needs a UiDocument to be right. The same split ConsoleModel makes, for the same reason: the decisions worth testing are all here and the view is bars and buttons over them.

⚠ Recording accumulates rather than replacing. Profiler.Collect empties the rings, so a model that rebuilt the capture from each tick's collect would show only the last sixteen milliseconds — and a capture button that produced a sixteen-millisecond window is one nobody can use. Samples are gathered across every tick between Start and Stop and become one capture at the end.

⚠ The rings are drained while recording even though nothing draws them yet. They overwrite when full, so a five-second capture of a busy thread would otherwise be the last sixty milliseconds of it with the rest silently gone. Draining per tick is what makes a long capture a long capture.

Fields and properties (10)

• public IReadOnlyList<IProfileSource> Sources

  The sources that can be profiled, in the order they were added.

• public IProfileSource? Selected

  Which one is selected, or when none has been added.

• public ProfilerState State

  Whether it is sampling.

• public ProfileCapture Capture

  The most recent finished capture.

• public ProfileCapture? Baseline

  What Capture is being compared against, or .

• public IReadOnlyList<ProfileDelta> Deltas

  The comparison, or an empty list when there is no baseline.

• public int Thread

  Which thread's chart is on screen, by index into the capture's threads.

• public int? Frame

  Which frame of the capture the chart is showing, or for all of them.

• public ProfileThread? Current

  The thread whose chart is on screen, or when there is none.

• public IReadOnlyList<FlameNode> Roots

  The roots the chart should draw, honouring Frame.

Events (1)

• public Action<ProfilerModel>? Changed

  Raised when the capture, the state or the selection changed.

Methods (7)

• public void Add(IProfileSource source)

  Adds a source.

• public bool Remove(IProfileSource source)

  Removes a source, stopping the capture if it was the one being recorded.

• public void Start()

  Starts sampling into a fresh capture.

• public void Tick()

  Takes whatever has been sampled since the last call.

• public void Stop()

  Stops sampling and turns what was gathered into a capture.

• public void MarkBaseline()

  Makes the current capture the thing later captures are compared against.

• public void ClearBaseline()

  Forgets the baseline.
