Re: How to not persist an object

OpenAMF uses JavaBeans introspection  to discover the "getter" methods.

If you implement a BeanInfo class, you can explicitly return an array of
PropertyDescriptor objects.
OpenAMF will process only properties that you include in the
PropertyDescriptor array.

Here's an example:

File:  Foo.java

public class Foo
{
    private String a;
    private String b;
   
    public Foo()
    {
       
    }
   
    public String getA()
    {
        return a;
    }
   
    public void setA(String value)
    {
        this.a = value;
    }

    public String getB()
    {
        return b;
    }

    public void setB(String value)
    {
        this.b = value;
    }
   
}


File:  FooBeanInfo.java

import java.beans.*;

public class FooBeanInfo extends java.beans.SimpleBeanInfo
{
    public PropertyDescriptor[] getPropertyDescriptors()
    {
        PropertyDescriptor[] props = new PropertyDescriptor[1];
        try
        {
           // Create a property descriptor for "a" only
            PropertyDescriptor pd = new PropertyDescriptor("a", Foo.class);
            props[0] = pd;
        }
        catch (IntrospectionException ex)
        {
            ex.printStackTrace();
        }
       
        return props;
    }

}
