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, K>(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>

[BOT] 实例检索——跨文件/组件获取已激活的 Engine 实例

只要引擎通过 useMeshFlow 初始化过，任何地方通过 ID 即可获取，无需 Prop Drilling。

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, K>(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>

Engine 对象，与 useMeshFlow 返回类型一致

Throws

MeshError.EngineNotFound — ID 对应的实例不存在

• useMeshFlow 创建引擎
