Subject [jira] [Commented] (LANG-1330) EqualsBuilder should be able to call custom equals method for specified class
Date Wed, 10 May 2017 15:00:08 GMT

    [ https://issues.apache.org/jira/browse/LANG-1330?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16004820#comment-16004820

Jason Smiley commented on LANG-1330:
------------------------------------

https://issues.apache.org/jira/browse/LANG-1249 might be sufficient, but, technically the
request here is to be able to call custom equal methods by class type so the burden.

In my implementation, I am technically using 2 different EqualsBuilder instances, so I am
not sure if the bug fix would be enough, but, when I walked through the code, you could see
the ignored fields were lost.

> As a tester, there are times I want to exclude certain fields (like ID) for my parent
object and its children.
> For example:
> {code}
> class Parent {
> public String id;
> public NormalChild child1;
> public SpecialChild child2;
> //uses ReflectionEqualsBuilder for equals();
> //has custom equalsWithoutID() method;
> }
> class NormalChild extend Child {
> public String name;
> //uses ReflectionEqualsBuilder equals();
> //has custom equalsWithoutID() method via inheritance;
> }
> class SpecialChild extend Child {
> public String id;
> public String name;
> //uses ReflectionEqualsBuilder for equals();
> //has custom equalsWithoutID() method via inheritence;
> }
> {code}
> If I am running a reflectionEquals with excluding field "id" on my parent object, the
excludedFields won't be used on my children classes (only excludes fields of parent with name).
I would like to be able to call the custom equalsWithoutID() if its an instance of class Child.
> Currently i need to do a workaround where my equals() checks to see which method I was
using before executing but its not an ideal solution.
