Struct ViewDelta

Namespace

Typhon.Engine

Assembly

Typhon.Engine.dll

A zero-allocation view into the delta state of a ViewBase (e.g. EcsView<TArchetype> or NavigationView<TSource, TTarget>).

Lifetime: This struct references the View's internal delta storage directly — no copies are made. The data is only valid until the next call to ClearDelta(). After ClearDelta(), all collections will appear empty. Do not cache this struct across refresh cycles.

Typical usage:

view.Refresh(tx);
var delta = view.GetDelta();
// Process delta.Added, delta.Removed, delta.Modified
view.ClearDelta();
// delta is now invalid — all collections report empty
