    <p>I have some questions about the concept of <em>static polymporhism</em> I somethimes hear about; you may interpret them primarily in the context of C++, but I'd appreciate language-agnostic answers where applicable (<em>hence tagging both C++ and language-agnostic</em>).</p> <ol> <li><p><strong>How do we <em>define</em> static polymorphism in general?</strong> As an example, I believe that the <code>std::sort</code> function from C++ shall be considered statically polymorphic as it depends on some interface provided by some objects which <em>behave like iterators</em>, and the <em>exact behaviour under the interface of provided iterators</em> can be determined in the compile-time. Is this explanation how we define static polymorphism, or is it just a description of a specific case and there's more to it?</p></li> <li><p><strong>What are the common code patterns</strong> of using static polymorphism in C++? Also: Is SP <em>only</em> achieved via templates in C++? </p></li> <li><p><strong>Is it true that</strong> a given UML class diagram doesn't <em>directly</em> describe how polymorphism is handled and, thus, it can be at least partially implemented either statically or dynamically? In other words: Is the choice of static vs dynamic polymorphism independent of the OOP model, and thus up to the implementor to decide?</p></li> <li><p><strong>Is static polymorphism only C++-specific</strong> and related to how templates work? If not, is it present in any other <em>mainstream languages</em> besides C++? Can we have an equivalent of static polymorphism in Java, C#.. anything, and will it bring any benefits?</p></li> <li><p>The most important... <strong>What are the actual benefits of using static polymorphism?</strong> I think we can agree that it reduces code flexibility; what are the advantages, besides - in the case of C++ - saving one pointer dereference (virtual function / pointer-to-function / delegate cost)? What is the <strong>class of problems</strong> where static polymorphism is especially useful, the right choice for implementation?</p></li> </ol>

    3. CONope, I meant flexibility; assuming that all designs with static polymorphism can be implemented with dynamic polymorphism, but not in the other way round- using static polymorphism for a specific case implies that a need might arise in the future to rewrite it dynamically, if requirements change. Just my thinking

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.
