@ParametersAreNonnullByDefault 是否也适用于方法返回值? [英] Is @ParametersAreNonnullByDefault applies to method return values too?

问题描述

文档@ParametersAreNonnullByDefault 说:

此注解可以应用于包、类或方法，以指示该元素中的方法参数默认为非空，除非...

This annotation can be applied to a package, class or method to indicate that the method parameters in that element are nonnull by default unless ...

我不认为方法的返回类型/值是它的参数.这只是其签名的一部分，所以这对我来说有点模棱两可.

I don't consider a method's return type/value to be it's parameter. It is only part of its signature, so this is kind of ambiguous for me.

Java 方法教程 似乎认为我.

正如 Joachim Sauer 在他的 answer，名称 @ParametersAreNonnullByDefault (parameters) 应该清楚地向我表明此注释不适用于方法的返回类型/值.我瞎了眼！:) 谢谢约阿希姆！

As Joachim Sauer pointed out for me in the comments section of his answer, the name @ParametersAreNonnullByDefault (parameters) should've clearly indicated for me that this annotation doesn't apply to methods' return types/values. I was blind! :) Thanks Joachim!

鉴于此，我只能说 @EverythingIsNonnullByDefault 应该存在于某处.:)

In light of this I can only says that an @EverythingIsNonnullByDefault should exist somwhere. :)

推荐答案

我不明白为什么 @ParametersAreNonnullByDefault 应该应用于返回值.

I don't see a reason why @ParametersAreNonnullByDefault should apply to return values.
