NetworkView

Remarks

The panel is NetworkView.vxml; this file exists only to make it public. The markup compiler emits a partial class with no accessibility modifier, which is internal — deliberately, so that a component is not public API by accident — and a panel the editor's diagnostics module constructs from another assembly has to be. One hand-written part is the whole of the mechanism.

⚠ A view and not an instrument. Everything it draws is a property Vixen.Net.Diagnostics already exposes — BandwidthLedger's five tables and its totals, and whatever SnapshotInspector.Inspect makes of a packet — and nothing in Vixen.Net was widened to build it. That is the claim doc 16's diagnostics section rests on, and the panel is what tests it.

⚠ It is a Component rather than a Control, which is a choice and not a constraint. Nothing outside the class reads a part of it: the host wires three delegates and the panel draws itself. A panel with no public parts is exactly what a component is for — see StatisticsView, which made the same call — and a test reaches one through UiDocument.ComponentAt rather than through a tree walk.

• protected override void OnUnmounted()

  Called when the component leaves the tree, before its effects are disposed.
