MeshFlow Core API / useEngine

Function: useEngine()

useEngine<M, P, NM, S, T>(id): Engine<{ batchRenderExport: { init: any; }; destroyPlugin: () => void; dispose: () => void; formExports: { }; GetAllDependency: () => number[][]; GetDependencyOrder: () => number[][]; GetGroupByPath: (path) => MeshFlowGroupNode<MeshPath>; GetValue: (path, key) => any; hasRenderGate: () => boolean; historyExports: MeshFlowHistory; notifyAll: () => Promise<void>; onError: (cb) => Unsubscribe; onStart: (cb) => () => void; onSuccess: (cb) => () => void; scheduler: MeshScheduler<T, P, any, NM>; SetRule: <K, TKeys>(outDegreePath, inDegreePath, key, options) => void; SetRules: <TKeys>(outDegreePaths, inDegreePath, key, options) => void; SetStrategy: (path, key, strategy) => void; SettleTasks: (array) => void; SetValue: (path, key, value) => void; SetValues: (updates) => void; SilentSet: (path, key, value) => boolean; StageValue: (path, key, value) => void; useEntangle: <State>(config) => void; usePlugin: (plugin) => () => void; validatorExports: { SetValidators?: (path, options) => void; }; }, M, P>

Defined in: engine/useEngineManager.ts:386

实例检索：跨文件/组件获取已激活的 Engine 实例

Type Parameters

M

M extends Record<string, any> = { }

动态插件类型 (可选)

P

P extends MeshPath = any

路径类型标识 (可选)

NM

NM extends Record<string, any> = Record<string, any>

S

S = any

T

T = any

Parameters

id

MeshPath

引擎实例的唯一 ID

Returns

Engine<{ batchRenderExport: { init: any; }; destroyPlugin: () => void; dispose: () => void; formExports: { }; GetAllDependency: () => number[][]; GetDependencyOrder: () => number[][]; GetGroupByPath: (path) => MeshFlowGroupNode<MeshPath>; GetValue: (path, key) => any; hasRenderGate: () => boolean; historyExports: MeshFlowHistory; notifyAll: () => Promise<void>; onError: (cb) => Unsubscribe; onStart: (cb) => () => void; onSuccess: (cb) => () => void; scheduler: MeshScheduler<T, P, any, NM>; SetRule: <K, TKeys>(outDegreePath, inDegreePath, key, options) => void; SetRules: <TKeys>(outDegreePaths, inDegreePath, key, options) => void; SetStrategy: (path, key, strategy) => void; SettleTasks: (array) => void; SetValue: (path, key, value) => void; SetValues: (updates) => void; SilentSet: (path, key, value) => boolean; StageValue: (path, key, value) => void; useEntangle: <State>(config) => void; usePlugin: (plugin) => () => void; validatorExports: { SetValidators?: (path, options) => void; }; }, M, P>

Description

只要引擎通过 useMeshFlow 或 defineMesh 初始化过，你就可以在任何地方通过 ID 直接拿到它。 无需 Prop Drilling，它是跨组件通讯的核心桥梁。

Throws

如果 ID 对应实例不存在则抛错
