Callback (ezasse-core 0.0.12 API)

类型参数:

P - The type of the argument provided to the call method.

R - The type of the return type of the call method.

函数接口:

这是一个函数接口, 因此可用作 lambda 表达式或方法引用的赋值目标。
```
@FunctionalInterface
public interface Callback<P,R>
```
The Callback interface is designed to allow for a common, reusable interface to exist for defining APIs that requires a call back in certain situations.
Callback is defined with two generic parameters: the first parameter specifies the type of the object passed in to the call method, with the second parameter specifying the return type of the method.
