    <p>From <a href="http://www.blackwasp.co.uk/LSP.aspx" rel="nofollow noreferrer">Liskov Substitution Principle - www.blackwasp.co.uk</a></p> <blockquote> <p>One common indication of non-compliance with the LSP is when a client class checks the type of its dependencies. This may be by reading a property of an object that artificially describes its type or by using reflection to obtain the type. Often a switch statement will be used to perform a different action according to the type of the dependency. This additional complexity also violates the Open / Closed Principle (OCP), as the client class will need to be modified as further subclasses are introduced.</p> </blockquote> <p>Does following techonolgies (that use reflection) cause a violation of LSP?</p> <ol> <li>Dependency Injection</li> <li>Inversion Of Control</li> </ol> <p>Note: I am from C# background.</p> <p>From <a href="http://blogs.msdn.com/b/simonince/archive/2008/06/30/dependency-injection-is-dead.aspx" rel="nofollow noreferrer">http://blogs.msdn.com/b/simonince/archive/2008/06/30/dependency-injection-is-dead.aspx</a></p> <blockquote> <p>Reflection; most (perhaps all?) Dependency Injection containers rely on some extent on Reflection – dynamically inspecting objects and determining their dependencies.</p> </blockquote> <p>REFERENCES:</p> <ol> <li><p><a href="https://stackoverflow.com/questions/6938071/hierarchy-violates-liskov-so-what">Hierarchy violates Liskov - so what?</a></p></li> <li><p><a href="https://stackoverflow.com/questions/10778354/how-can-i-avoid-breaking-liskov-substitution-principle-lsp">How can I avoid breaking Liskov Substitution Principle (LSP)?</a></p></li> <li><p><a href="https://stackoverflow.com/questions/12921465/does-liskov-substitution-principle-also-apply-to-classes-implementing-an-interfa">Does Liskov Substitution Principle also apply to classes implementing an interface?</a></p></li> <li><p><a href="https://stackoverflow.com/questions/3996819/does-this-violate-the-liskov-substitution-principle-and-if-so-what-do-i-do-abo">Does this violate the Liskov substitution principle, and if so, what do I do about it?</a></p></li> <li><p><a href="https://stackoverflow.com/questions/8368684/does-gwts-activitymapper-violate-the-liskov-substitution-principle">Does GWT&#39;s ActivityMapper violate the Liskov Substitution Principle?</a></p></li> </ol>

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.
