    <p>I'm wondering how the following code is optimized. Specifically concerning virtual and direct calls. I have commented on how I think everything is optimized but those are just guesses.</p> <pre><code>public abstract class Super { public abstract void Foo(); public void FooUser() { Foo(); } } public class Child1 : Super { public override void Foo() { //doSomething } } public class SealedChild : Super { public override void Foo() { //doSomething } } class Program { void main() { Child1 child1 = new Child1(); child1.Foo(); //Virtual call? child1.FooUser(); //Direct call and then a virtual call. SealedChild sealedChild = new SealedChild(); sealedChild.Foo(); //Direct call? sealedChild.FooUser(); /* Two options: either a direct call &amp; then a virtual call * Or: direct call with a parameter that has a function pointer to Foo, and then a direct call to foo. */ Super super = child1; super.Foo(); //Virtual call. super.FooUser(); //Virtual call then direct call. } } </code></pre>

    1. COYour "SealedClass" is not actually defined as sealed. So it would be no different from your Child1 class.

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.
