Perhaps you can add a method to Constraint that accepts a closure containing the constraint you want to enforce. I don’t think this is possible without a wildly complex implementation.

I want to add a Groovy DSL on top of a Java package that has classes Var and Constraint. I want a user to be able to write something like Constraint constraint = var1 < var2 Is it possible to override Groovy comparison operators like “<” that should return an instance of my class Constraint instead of int? If yes I would appreciate a hint. Jacob Eric,
Could you advise on this question? I want to add a Groovy DSL on top of a Java package that has classes Var and Constraint. I want a user to be able to write something like

Constraint constraint = var1 < var2

Is it possible to override Groovy comparison operators like “<” that should return an instance of my class Constraint instead of int? If yes I would appreciate a hint.

I really have to dig in Groovy urgently... But I need more time in one day! Awesome! I really have to dig in Groovy urgently… But I need more time in one day!
