在编译时强制异常捕获 [英] Forcing Exception Catching At Compile Time
问题描述
有没有办法强制对象的用户捕获
特定类型的异常？
，例如，如果异常''ExeceptionXXX''抛出
方法''ThrowsExceptionXXX''未被捕获，则会发出编译错误。
谢谢，
bryan
is there a way to force the user of an object to catch exceptions of
specific type?
for instance a compile error is issued if exception ''ExeceptionXXX'' thrown
by method ''ThrowsExceptionXXX'' is not caught.
thanks,
bryan

无法做到这一点。例外情况不需要用于抛出它们的函数
，甚至是一级（如果是这样的话，他们会'b $ b没有什么目的，你' 我只是回来了。
No way to do that. Exceptions need not be caught in the function
that throws them, or even one level up (if that were the case, they''d
have little purpose, you''d just return instead).

不，不在抛出它们的函数中。我不确定我的问题是否清楚。
i想知道是否有办法迫使编译器检查是否有
异常可通过相关方法抛出。如果对该方法的调用
不在try / catch块中，则会产生编译时错误。
类似于java。
谢谢，

no, not in the function that throws them. i''m not sure if my question was
clear.
i want to know if there is a way to force the compiler to check to see if an
exception is throwable by the method in question. if a call to that method
is not in a try/catch block a compile time error is produced.
similar to java.
thanks,

C ++没有检查异常。它有例外规格，它与b $ b不是一回事。如果您愿意，可以谷歌搜索此主题。在C ++社区中有一种广泛的感觉，即在C ++中实现的异常规范并不是很有帮助。
