The complicated reasons for - why such a method is necessary are explained in this paper: (TODO: Find link to Venners/Spoon/Odersky). If all classes in a hierarchy are a mix of scala case classes - and classes with lombok-generated equals methods, all equality will 'just work'. If you need to write your own equals methods, you should always override <code>canEqual</code> - if you change <code>equals</code> and <code>hashCode</code>. + why such a method is necessary are explained in this paper: <a href="http://www.artima.com/lejava/articles/equality.html">How to Write an Equality Method in Java</a>. + If all classes in a hierarchy are a mix of scala case classes and classes with lombok-generated equals methods, all equality will 'just work'. + If you need to write your own equals methods, you should always override <code>canEqual</code> if you change <code>equals</code> and <code>hashCode</code>. </p> </div> <div class="snippets"> |
