Examples of er.extensions.foundation.ERXMutableInteger

er.extensions.foundation.ERXMutableInteger
ERXMutableInteger is like {@link java.lang.Integer Integer}but mutable, to avoid the excess object creation involved in i = new Integer(i.getInt() + 1) which can get expensive if done a lot.
Not subclassed from Integer, since Integer is final (for performance.)
