-------------------------------------
Hi [~erans] , is this still open to be picked? I wanted to work on this feature.
> Check for "deep" copy
> ---------------------
>
> Key: LANG-1709
> URL: https://issues.apache.org/jira/browse/LANG-1709
> Project: Commons Lang
> Issue Type: Wish
> Components: lang.builder.*
> Reporter: Gilles Sadowski
> Priority: Minor
> Labels: api, copy, deep, reflection, utility
>
> Wouldn't it be useful to have a way to easily check whether some object is a
> deep copy of another? I.e. the two instances could be "equal" but the utility
> function would return "false" if they share a mutable field.
> More generally, how about a function like
> {code:java}
> public SomeUtils {
> /**
> * @return true if "a" and "b" do not share any mutable field.
> */
> public static <T> boolean areIndependent(T a, T b) { /* ... */ }
> // ...
> }
> {code}
> ?
> It seems that this could (?) be built upon
> [{{ReflectionDiffBuilder}}|https://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/builder/ReflectionDiffBuilder.html].
