This paper presents a small extension to the Java language with dependent types and inheritable constructors. A dependent type is the most specific type of a given object. In essence it is already known in other languages such as Eiffel. There the definition was unfortunately flawed. Also ...
Constructor类是Java反射中重要的类,它是对类中构造器的描述的类。类似于Method(对类中方法的描述的类),Field(对类中属性的描述的类),我们通过创建Constructor的对象实例,就可以创建源对象。 Constructor /** * {@codeConstructor} provides information about, and access to, a single * constructor for a class...
