Subject [jira] [Created] (LANG-706) Create a MutableNumber interface with methods common to all the mutable numbers
Date Tue, 14 Jun 2011 19:22:47 GMT
Create a MutableNumber interface with methods common to all the mutable numbers
-------------------------------------------------------------------------------

                 Key: LANG-706
                 URL: https://issues.apache.org/jira/browse/LANG-706
             Project: Commons Lang
          Issue Type: Improvement
          Components: lang.mutable.*
            Reporter: Juan Carlos Estibariz
            Priority: Minor


With this interface it would be possible to perform generic operations on mutable numbers
without worrying about the specific type, e.g.

// these two could be created in a different methods
MutableNumber m = new MutableDouble();
Number n = ...;

// this would do the right thing
m.add(n);

(I'm not just making this up, I have a real use case and I had to create all the classes myself)
