How to specifically suppress "Comparing identical expressions" in Eclipse-Helios JDT


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!


Solution

  • Officially, there are only 3 supported arguments to @SuppressWarnings(), as specified by the standard $9.6.4.5:

    • Unchecked warnings (§4.8, §5.1.6, §5.1.9, §8.4.1, §8.4.8.3, §15.12.4.2, §15.13.2, §15.27.3) are specified by the string "unchecked".
    • Deprecation warnings (§9.6.4.6) are specified by the string "deprecation".
    • Removal warnings (§9.6.4.6) are specified by the string "removal".

    But, in small text, the standard mentions support for extra types:

    For other kinds of warnings, compiler vendors should document the strings they support for @SuppressWarnings. Vendors are encouraged to cooperate to ensure that the same names work across multiple compilers.

    These are supported by some compilers:

    So, there is nothing which might help you.
