--------------------------------
> CompareToBuilder's doc doesn't specify precedence of fields it uses in

> Key: LANG-827
> URL: https://issues.apache.org/jira/browse/LANG-827
> Project: Commons Lang
> Issue Type: Improvement
> Components: lang.builder.*
> Affects Versions: 3.1
> Reporter: david cogen
> Assignee: Duncan Jones
> Labels: documentation
> Fix For: 3.4
>
>
> The doc does not specify in what order the fields declared using append() are
> applied. So if for example I use CompareToBuilder to build a comparator for a
> class Complex (2 doubles), and I use append(c.real) followed by
> append(c.imag), does the comparison consider the real or imaginary part "more
> important" for the final result of the comparison.
> And similarly, the reflection versions also don't specify the order of the
> fields they consider.
> Yes, I can experiment to determine the behavior. Which I am about to do. But
> I am not comfortable relying on experimentally-determined, undocumented
> behavior for correcteness. Which is why I classified this as Major priority,
> not Minor or Trivial.
