----------------------------------------
Summary: Checkstyle must support MagicNumbers rule
Key: IGNITE-11902
URL: https://issues.apache.org/jira/browse/IGNITE-11902
Project: Ignite
Issue Type: Bug
Reporter: Maxim Muzafarov
Add support <module name="MagicNumber"/> to checkstyle plugin.
Checks that there are no "magic numbers" where a magic number is a numeric
literal that is not defined as a constant. By default, -1, 0, 1, and 2 are not
considered to be magic numbers.
Constant definition is any variable/field that has 'final' modifier. It is fine
to have one constant defining multiple numeric literals within one expression:
{code}
static final int SECONDS_PER_DAY = 24 * 60 * 60;
static final double SPECIAL_RATIO = 4.0 / 3.0;
static final double SPECIAL_SUM = 1 + Math.E;
static final double SPECIAL_DIFFERENCE = 4 - Math.PI;
static final Border STANDARD_BORDER = BorderFactory.createEmptyBorder(3, 3, 3,
3);
static final Integer ANSWER_TO_THE_ULTIMATE_QUESTION_OF_LIFE = new Integer(42);
{code}
