# 引用(Ref)

Ref objects store up-to-date references to a Point or Range object in the document.

Ref 对象在文档中存储对 点(Point) 或 范围(Range) 对象的最新引用。

# 点引用(PointRef)

PointRef objects keep a specific point in a document synced over time as new operations are applied to the editor. You can access their property current at any time for the up-to-date Point value.

当新操作应用到编辑器时，PointRef 对象使文档中的特定点的信息随时间同步。 您可以随时访问其 current 属性来获取最新的 Point 值。

interface PointRef {
    current: Point | null
    affinity: 'forward' | 'backward' | null
    unref(): Point | null
}

# Static methods

# PointRef.transform(ref: PointRef, op: Operation)

Transform the point refs current value by an op.

通过一个 op 转换成 点 Point 引用的当前值。

# 范围引用(RangeRef)

RangeRef objects keep a specific range in a document synced over time as new operations are applied to the editor. You can access their property current at any time for the up-to-date Range value.

当新的操作应用到编辑器时，RangeRef 对象使文档中的特定范围随时间同步。 您可以随时访问其属性 current 来获取最新的 Range 值。

interface RangeRef {
    current: Range | null
    affinity: 'forward' | 'backward' | 'outward' | 'inward' | null
    unref(): Range | null
}
