Something like this should work:

/**
 * Returns properties for JavaFX object.
 */
public List <Property> getProperties(Object anObj)
{
    // Create list and get class methods
    List <Property> properties = new ArrayList();
    Method methods[] = anObj.getClass().getMethods();
    
    // Iterate over methods, if method returns property, get it
    for(Method method : methods) {
        if(Property.class.isAssignableFrom(method.getReturnType()))
            try { properties.add((Property)method.invoke(anObj, new Object[0]));
}
            catch(Exception e) { System.err.println("Error: " + e); continue; }
    }
    
    // Return properties
    return properties;
}
