@Xml... annotation telling schemagen to ignore a method completely

Question

Hi all,
I write Java Beans and annotate them by @Xml... annotations in the source code. I am able to generate a proper schema from the classes and to marschal a class into a XML document, etc.. I am missing one thing: I would like the marshalable classes to have some methods which would be totally ignored during generating the schema, marshalling and unmarshalling and which could use any classes not described and not included in the schema. Actually, I am wrinting a persistent representation of classes which I cannot change as they are a part of a JAR distribution - I would like the Java Bean classes to have methods for a creation of the non-persistent classes which the persistent classes represent.
I am missing a @Xml... annotation that would tell the schemagen, Marshaller and Unmarshaller to ignore these methods (no matter what types of classes they return, use as parameters). The @XmlTransient seemed to be the closest one, but it is not applicable to methods. Does there exist an annotation for or just a way of having such methods in a marshallable class that would be completelly ignored by JAXB 2.0? (I assume that e.g. during unmarshalling is taken the appropriate class and the properties are initialized in accordance to the content of the XML document and methods are not affeted anyhow.)
Thanks,
Bebe

This post was great!  Thank you so much.  But I am hoping you know one more thing related to this.  In the "transform" section of the definition (where the x/y coordinates are set along with height and width) there is an option called "angle".  I was hoping that changing this value would allow me to offset the angle of the picture.  However, if I put any value there other than 0 the template becomes unusable.
Do you happen to know what this option does?
I haven't looked into the files, so this is just a guess based on how some graphic applications work. It's common to think of rotating a shape as pivoting around a center point, but It's possible that the file sets a value for the rotation point not at the center. In some graphics applications, you can set a shape's pivot at any corner or in the middle of any side, of the rectangle that contains the whole shape.
So, your value may be rotating the shape around a pivot that moves the shape into some area that upsets the behavior of other shapes. Just a thought.

Peter's point is a good one.  I would also assume that the "angle" property allows you to rotate an image, but I haven't tried it myself.  One thing to investigate - are there any page templates included in LR that have image placeholders that are at an angle (I don't recall any, off-hand)?  If so, looking at the associated .lua file could provide insight into how an angled image placeholder should be described.
