 当开发者创建自定义组件，想对该组件添加特定功能时（如：仅对自定义组件添加一个点击跳转操作）。若直接在组件内嵌入事件方法，将会导致所有初始化该组件的地方均增加了该功能。为解决此问题，引入了@BuilderParam装饰器，此装饰器修饰的属性值可为@Builder修饰的方法，开发者可在初始化自定义组件时对此属性进行赋值，为自定义组件增加特定的的功能。
 
 ### 参数初始化组件
-通过参数初始化组件时，将@Builder装饰的方法赋值给@BuilderParam修饰的属性，并在自定义组件内调用content属性值。
+通过参数初始化组件时，将@Builder装饰的方法赋值给@BuilderParam修饰的属性，并在自定义组件内调用content属性值。对@BuilderParam修饰的属性进行赋值时不带参数（如：`content: this.specificParam`），则此属性的类型需定义成无返回值的函数（如：`@BuilderParam content: () => void`）。若带参数（如：`callContent: this.specificParam1("111")`），则此属性的类型需定义成any（如：`@BuilderParam callContent: any;`）。
