const { deep = false, immediate = false } = options
return createDecorator((componentOptions, handler) => {
if (typeof componentOptions.watch !== 'object') {
componentOptions.watch = Object.create(null)
}
(componentOptions.watch as any)[path] = { handler, deep, immediate }
})
}示例3: Inject
export function Inject(options?: { from?: InjectKey, default?: any } | InjectKey): PropertyDecorator {
return createDecorator((componentOptions, key) => {
if (typeof componentOptions.inject === 'undefined') {
componentOptions.inject = {}
}
if (!Array.isArray(componentOptions.inject)) {
componentOptions.inject[key] = options || key
}
})

export function Provide(key?: string | symbol): PropertyDecorator {
return createDecorator((componentOptions, k) => {
let provide: any = componentOptions.provide
if (typeof provide !== 'function' || !provide.managed) {
const original = componentOptions.provide
provide = componentOptions.provide = function (this: any) {
let rv = Object.create((typeof original === 'function' ? original.call(this) : original) || null)
for (let i in provide.managed) rv[provide.managed[i]] = this[i]
return rv
}
provide.managed = {}
}
provide.managed[k] = key || k
