# SetStrokePointsCommand

Import it from `@grafloria/engine`.

Also has every member of `Command`, listed on its own entry.

Replace an ink stroke's point list, undoable. The stroke-edit tool's commit:
a drag that translates a stroke ends in exactly ONE of these at pointer-up.

Mirrors {@link SetLinkPointsCommand }, minus the `hasManualWaypoints` bookkeeping
— a stroke's points are ALWAYS authored content (nothing re-routes them), so
there is no derived/manual flag to keep in step.

COLLAB: execute()/undo() each call `setPoints` exactly ONCE, and `points` on a
stroke is a per-property register, so stroke geometry reaches peers. One gesture therefore puts
ONE op on the wire — never per-pointermove spam, never a class instance.

The FROM snapshot is taken from the model on first execute() when the caller
did not supply one — but the stroke-edit tool DOES supply it (the gesture-start
geometry), because by commit time a live-feedback path may already have the
model sitting at TO, and a FROM read then would make undo a no-op.

```ts
class SetStrokePointsCommand extends Command
```

**Methods**

- `constructor( private strokeId: string, newPoints: readonly StrokePoint[], oldPoints?: readonly StrokePoint[] )`
- `override execute(context: CommandContext): void` — Execute the command
- `override undo(context: CommandContext): void` — Undo the command
- `override canExecute(context: CommandContext): boolean` — Check if command can be executed
- `override canUndo(context: CommandContext): boolean` — Check if command can be undone
- `override canMergeWith(): boolean` — One edit gesture = one undo step; never merge two of them.
- `override serialize(): SerializedCommand` — Serialize command
- `override getDescription(): string` — Get description for UI
