PointRef objects keep a specific point synced over time as operations are
applied. They are low-level location values used by Slate internals and
advanced runtime code.
Shape
Read current for the up-to-date Point value. Call unref() when you no
longer need to track the point. affinity controls which side the point follows
when content is inserted at the current position.
interface PointRef {
current: Point | null;
affinity: "forward" | "backward" | null;
unref(): Point | null;
}interface PointRef {
current: Point | null;
affinity: "forward" | "backward" | null;
unref(): Point | null;
}Instance Methods
unref() => Point | null
Call this when you no longer need to sync this point. It also returns the current value.
Static Methods
Transform Methods
PointRefApi.transform(ref: PointRef, op: Operation)
Transform the point ref's current value by an op.
The editor calls this as needed, so normally you won't need to.
