Body
I have some difficulty in understanding your question. I try here to summarize your problem statement,please comment if this is indeed what your question is. (I would have put this as a comment but the number of characters exceed 600) <li>You have classes <code>ImageA</code> and <code>ImageB</code> that are subclasses of <code>Image</code></li> <li>Constructor for both these classes is the same and accepts a path argument (which I presume to be the path of image file)</li> <li>Classes <code>ImageA</code> and <code>ImageB</code> use different attributes to represent the image <li>Common attributes classes <code>ImageA</code> and <code>ImageB</code> are kept in the base class (like the path attribute) <li>You declare an abstract method <code>compare</code> which takes an <code>Image</code> type as argument and returns a double value <li>The goal is to pass to compare method of <code>ImageA</code> a type of <code>ImageB</code> and the return value would indicate which concrete image representation is better. So this would mean that implementation of <code>compare</code> method should be such that, <code>compare</code> method in class <code>ImageA</code> will be called with instance of type <code>ImageB</code> and viceversa will be the implementation in class <code>ImageB</code> <li>The compare method in classes <code>ImageA</code> and <code>ImageB</code> cannot use methods in <code>Image</code> since they have different attributes If this problem statement indeed represents your problem, then I think is without resorting to checks like <code>instanceof</code> and casting it won't be possible to do the comparison between classes <code>ImageA</code> and <code>ImageB</code>. Though there is an abstract class <code>Image</code> the <code>compare</code> method still depends on what image attributes (which are not the same) the child classes use to represent an image.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
