--------------------------------
Summary: CompareToBuilder's doc doesn't specify precedence of
fields it uses in performing comparisons
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
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.
