[jira] [Created] (LANG-1235) Add decrementAndGet/incrementAndGet to MutableInt class

Sebb created LANG-1235:
--------------------------

             Summary: Add decrementAndGet/incrementAndGet to MutableInt class
                 Key: LANG-1235
                 URL: https://issues.apache.org/jira/browse/LANG-1235
             Project: Commons Lang
          Issue Type: New Feature
            Reporter: Sebb


Frequently when incrementing or decrementing a number, one needs to compare it to a limit. For example in loops.

At present that requires two calls:

MutableInt.decrement()
MutableInt.getValue()

It would be convenient to have a method that combined the two.

c.f. AtomicInteger.decrementAndGet()

There is less likelihood of needing these methods for other Mutable Number types as they are not often used in loops.
