如何快速生成class的setter和getter方法 如何实现Sendable类型和JSON数据的转换 如何处理大整数 如何通过判断函数入参类型实现不同代码逻辑 如何使用工具库对JSON进行解析与生成 A持有B,B引用A的场景会不会导致内存泄漏 如何通过key获取对象值 ModuleManager模块加载流程是什么样的?
UsingObject.getOwnPropertyDescriptors(instance)you can get these getters and setters and apply thewatching logic being done here. This will also make it easier to integrate with type systems like Flow in the future (Flow understands the syntax but doesn't type check getters/setters). The prima...

It can be only accessed within the class in which it is declared. get and set methods are used to access & modify the value of a private field respectively from outside the class in which it is declared. They are called getters and setters method....
在javaBean中,对于属性的定义也不同于普通类中的属性定义,javaBean的属性是指setter和getter方法名中所包含的属性名,即使JavaBean类中没有定义此名称的实例变量,也可以成为JavaBean方法,即有方法就可以,这种定义方式扩展了属性的定义,融入了对javaBean所封装的业务功能状态的表示。
