Err, I tried to enclose the patch, however, ezmlm complained about the file size (abour 250KB). Any ideas? Well, I'm just resending the original message.
===== Hello, First of all, thanks for all your commons-good-work! While doing commons-lang stuff, I found the repetitive nature of Builder stuff. Therefore, i decided to: a) Create a SingleBuilder (for ToString / HashCode) and a DualBuilder (CompareTo / Equals) interface, and make their classes implementing; b) Create a SingleBuilderVisitor and DualBuilderVisitor; c) Do the proper wiring, while creating new constructors using the visitors; d) Create new tests and ensuring javadoc plays nice along; There's a patch attached in this e-mail, done against the latest svn STABLE url for 2.2 (http://svn.apache.org/repos/asf/jakarta/commons/proper/lang/branches/LANG_2_2_X/) There might be errors, but methinks it's a great idea to declare a constant like this in your source code. private static final EQUALS_VISITOR = new DualBuilderVisitor() { public void visit(DualBuilder builder, Object lhs, Object rhs) { Type lhsObj = (Type) lhs; Type rhsObj = (Type) rhs; builder.append(lhsObj.getId(), rhsObj.getId()).append(lhsObj.getName(), rhsObj.getName()); } }; And then, declare and instantiate builders like as, say: public boolean equals(Object anotherObj) { return new EqualsVisitor(EQUALS_VISITOR, this, anotherObj); } Please note this implementation, overrall, also lets you easily use a single visitor for either equals and compareto, thus creating a single point of management for all your field-maintenance-in-value-objects-needs.
