如何专门抑制“比较相同的表达式”在 Eclipse-Helios JDT 中
我尝试用注释封闭方法，
@SuppressWarnings("compareIdentical")
但这不起作用（更糟糕的是，注释会导致其自己的 Unsupported @SuppressWarnings("compareIdentical") 警告！）
我知道我总是可以使用，
@SuppressWarnings("all")
但是'警告抑制会比我想要的更多。
FWIW，我从 http://help.eclipse.org/helios/index.jsp?topic=/org.eclipse.jdt.doc.isv/guide/jdt_api_compile.htm（万岁玛丽通行证，可以肯定的是）。
谢谢！
I tried annotating the enclosing method with
@SuppressWarnings("compareIdentical")
but this does not work (worse yet, the annotation results in its own Unsupported @SuppressWarnings("compareIdentical") warning!)
I know that I can always use
@SuppressWarnings("all")
but that'd be more warning-suppression than I want.
FWIW, I got the "compareIdentical" string from the "Warning Options" table in http://help.eclipse.org/helios/index.jsp?topic=/org.eclipse.jdt.doc.isv/guide/jdt_api_compile.htm (a hail-mary pass, to be sure).
Thanks!

正式而言，
@SuppressWarnings()仅支持 3 个参数，如 标准 $9.6.4.5：但是，在小文本中，该标准提到了对额外类型的支持：
一些编译器支持这些：

Officially, there are only 3 supported arguments to
@SuppressWarnings(), as specified by the standard $9.6.4.5:But, in small text, the standard mentions support for extra types:

这样就可以了（至少在 Eclipse 中）：
This does it (in Eclipse at least):
