I'm trying to customize checkstyle checkers.

For example,

I want the MagicNumber checker to detect only constant 0 for all code patterns except for-statement.

'for statement' is allowed to use -1, 0 and 1.

Could you let me know how I can customize this checker or other checkers?

Most Checkstyle checks can be customized in some way. The exact options (called properties) available vary by check. Each check documents its properties.

So, for instance, MagicNumber has these options. Unfortunately, the properties you are looking for (to allow magic numbers in for loops; to detect only certain individual numbers) are not available.

In such a case, you must write your own check, potentially as a subclass of the check you want to modify.

My personal recommendation is to use the MagicNumber check as-is, and fix all the magic numbers, especially those in for loops. But that's just me. ;-)

  • Thanks for your reply. I really need to create my own checker for our domain-specific reasones. For example, we have many 3rd party codes and we don't modify those for maintenance. So... I may add other related questions to create checkers after reviewing. Thanks ~~ – 500004dolkong Aug 01 '13 at 06:10
