这个相对于上面来说比较复杂,主要用来转换一个类型到另一个继承体系类型。举个例子,如果需要String转成Enum以及他的子类,这时可以使用ConverFactory这个接口来定义类型转换。 接口定义如下 package 1. String转换成Enum的例子如下 public 1. GenericConverter 这个比之前的类型转换接口更加强大,可以在多种类型到多种类型之...
Now let's say, you have an enum string value say, "FirstName" and now you want to convert it to Enum value. The following code converts from a string to enum value, where Developer.SortingBy is of type SortFilter enumeration: // Conversion from String to Enum Developer.SortingBy = (...
