Subject [jira] Commented: (LANG-395) annotations based builders
Date Sat, 04 Jul 2009 01:04:47 GMT

    [ https://issues.apache.org/jira/browse/LANG-395?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12727165#action_12727165

Vincenzo Vitale commented on LANG-395:
--------------------------------------

Have a look here:

I think it would be easy to port the code (after some review) to commons lang.


Cheers,

> What about enabling the builders (ToStringBuilder, EqualsBuilder, etc.) that use reflection
to use annotations to find the field to include?
> Something like:
> ToStringBuilder.annotationsBasedToString(Object object, Class<Annotation> class,
Class<?> reflectUpToClass)
> One could use the JPA-Annotation @ID for example, espescially for Equals- and HashCodeBuilder.
There should also be some default annotation comming with LangTwo.
> Usage:
> public class User
> {
>   @StringRepresentation
>   @EqualsAndHashCode
>   private String name
>   @StringRepresentation
>   private String email;
>   private String password;
>   // ...
>   @Override
>   public String toString()
>   {
>     return annotationsBasedToString(this);
>   }
>   @Override
>   public boolean equals(Object other)
>   {
>     return annotationsBasedEquals(this, other);
>   }
>   @Override
>   public int hashCode()
>   {
>     return annotationsBasedHashCode(this);
>   }
> }
