Is there a way to customize your getter from a jaxb unmarshalling?

Question

I have a schema where I would like to customize the resulting getters from its unmarshalling.

What kind of custom binding would allow me to do that? An example would be a getter where I initialize the object with some default values before returning it, in the case that the object is NULL.

eg

public smapleType getSampleObject() { (if sampleObject == NULL) sampleObject.setField(0); return sampleObject; }

Is there a way to get JAXB to generate a customized getter like that?

You can do this by creating subclasses of your domain classes and ObjectFactory - more details here https://jaxb.java.net/guide/Adding_behaviors.html

Since you name this NULL thingy an example, I assume you're interested in a more general approach.

As cases like in your example are very specific, there's no universal customization for that. The closed would probably be the -Xinject-code plugin.

If you want deep customization of the generated code, then a hardcore way of writing an XJC plugin is probably the only one generic enough. But it's not quite easy.
