类 InvokeProxy

java.lang.Object

xyz.scootaloo.console.app.util.InvokeProxy

public final class InvokeProxy
extends Object

传递或者调用会抛出异常的方法

对 try-catch 的异常处理方式进行了包装，当需要调用会抛出异常的方式时，例如:

 public File getFile(String filename) throws NoSuchFileException {
     // some code ...
 }

调用时 InvokeProxy.fun(fileUtils::getFile).call("filename") , 这样完成调用。 这里 fun() 的参数是要调用方法，call() 的参数是要调用的方法的实际参数。
当方法抛出异常时，call() 调用返回 null，这里提供一些便捷的操作:

  - 添加异常处理器:  

  - 调用方法时抛出异常时指定默认值: FunctionDesc.NonRtnMethod.xAddHandle(Class, Consumer) 

  - 使方法返回的结果用Optional包装返回: FunctionDesc.Rtn0pWrapper.addHandle(Consumer)
