[castor-user] How to generate other types of code, besides POJOs

[Alex Thieme]

I know that castor can generate Java classes (what I would consider  
POJOs); but, is there an option to generate a file or files from any  
arbitrary template and XSD? I'll provide examples in case my  
explanation is not clear.

In the example below, there's an Adjustment.xsd, containing three  
attributes. The generator writes out a class header (package and  
import statements of my choosing), then writes a statement  
representing the "singleton" instance. Then, a "format" method is  
generated. Again, AdjustmentNativeFormatter (below) is the result of  
applying the Adjustment.xsd to a generator, say "FormatterGenerator"  
because this generator generates "Formatter" objects.

What I can't find in castor is the piece of code that I could write,  
either in XML or more likely Java code, which has access to the  
metadata in the XSD (the root elements, nested elements, attributes,  
whether something is a simple type or complex type, XML Schema type,  
etc). From that, I would write code to iterate over the elements and  
attributes, write out statements that will be written to a file on disk.

As you can see, this is different from generating simply POJOs. I'd  
like to be able to generate any arbitrary code from XSD.

And, dare I ask, if castor does not have this feature, can you  
recommend other open source projects that do have this feature?

Thanks in advance,

Alex

Generated code:
package com.athieme.KToW.formatters;

import org.apache.log4j.Logger;
import java.math.BigInteger;
import java.util.Calendar;
import com.athieme.AbstractFormatter;
import com.athieme.interfaces.IAdjustment;

public class AdjustmentFormatter extends
AbstractFormatter<IAdjustment> {

    public static final AdjustmentFormatter singleton = new
AdjustmentFormatter();

    public String format(final IAdjustment obj) {
        final StringBuffer sb = new StringBuffer();
        sb.append(obj.company());
        sb.append(obj.userId());
        sb.append(obj.dateStamp());
        sb.append(obj.timeStamp());
        return sb.toString();
    }
}
