Re: Modify the property of an object via Deferred Binding

I am no stranger to generators and/or annotation processors.  I think, if that is "really easy" then what I am proposing is the equivalent of "a goldfish could do it" (this is a favorite saying of one of my professors in college, the one that taught mainframe assembly).  

The generator that uses the compile time file feels like a better solution, but I think that something that does that for you should be part of the framework.

I think I will go that route though and when it's good enough, maybe I'll offer it up as a patch.  Was just hoping that there was already something in place that I was missing.

The reason is that you aren't really creating a new implementation of the logic, so i feel that having to create a class to set a property is a bit redundant/ridiculous.

Yeah maybe my example is a bit off. I think in reality I would have created a configuration interface that has getters for each config value and then provide different implementations of that configuration interface. Then I would pass in that configuration to the real class that contains the logic. IMHO that feels a lot better to me since you don't end up with empty sub classes only to call a super constructor with different parameters. It is also a lot more descriptive.

For such configuration classes, writing a generator is really easy. GWT actually has a generator that kind of does what you want. Take a look at UserAgentGenerator which generates an implementation of UserAgent. The generator code that produces UserAgent.getCompileTimeValue() is exactly what you need to generate a configuration class that simply returns compile time XML property values.
