Class: EditEngine ​

Defined in: packages/editor-core/src/engine.ts:41

编辑引擎：dispatch 走 校验→applyForward→入栈→清 redo→emit。 undo/redo 复用泛型 applyForward/applyReverse，只认 added/removed/modified， 对要素数量变化（split 1→2、merge 2→1）零特判。

Defined in: packages/editor-core/src/engine.ts:49

Methods ​

adoptServerState() ​

ts
adoptServerState(serverFeatures): void;

Defined in: packages/editor-core/src/engine.ts:159

采纳服务端权威状态（409 冲突 rebase）：以服务端要素覆盖/补齐本地同 id 要素， 并清空历史栈（rebase 后旧历史不再有效）。本地未提交编辑由调用方在 commit 前后取舍。

Parameters ​

serverFeatures ​

EditableFeature[]

Returns ​

void

dispatch() ​

ts
dispatch(cmd): EditResult;

Defined in: packages/editor-core/src/engine.ts:60

Parameters ​

cmd ​

Command

Returns ​

EditResult

getFeature() ​

ts
getFeature(id): EditableFeature | undefined;

Defined in: packages/editor-core/src/engine.ts:137

Parameters ​

id ​

string

Returns ​

EditableFeature | undefined

on() ​

ts
on(listener): () => void;

Defined in: packages/editor-core/src/engine.ts:114

Parameters ​

SnapshotListener

Returns ​

() => void

onTransaction() ​

ts
onTransaction(listener): () => void;

Defined in: packages/editor-core/src/engine.ts:120

提交后端回包后，把临时 id 替换成真实 id（状态 + 历史栈一并改）。

Parameters ​

idMap ​

Record<FeatureId, FeatureId>

Returns ​

void

setVersions() ​

ts
setVersions(versions): void;

Defined in: packages/editor-core/src/engine.ts:143

写入后端下发的版本号（乐观锁）。

Parameters ​
