    <p>This is probably a really obvious question but I want to be sure about it before going on with my development.</p> <p>I have a templated class something like:</p> <pre><code>template&lt;TypeA var1, TypeB var2&gt; class myClass { //Attributes ... //Methods ... void checkHit(vector&lt;Real&gt;* path, vector&lt;bool&gt;* active) { for(int i = 0; i &lt; N; i++) { //Some process bool hit = ((var1 == Up) || (var1 == Down)); } //... bool flag = ((var2 == Left) || (var2 == Right)); } } </code></pre> <p>If I create and object like</p> <pre><code>myClass obj&lt;Up, Right&gt;(...); </code></pre> <p>When executing the method</p> <pre><code>obj.checkHit( ... ); </code></pre> <p>Will the program just check for <code>bool hit = ((var1 == Up)</code> and <code>(var2 == Right)</code> ?? In other words, will the compiler throw away the code that doesn't has to do with the template-parameters passed? What I mean is if the resulting code after compiling will be something like</p> <pre><code>template&lt;TypeA var1, TypeB var2&gt; class myClass { //Attributes ... //Methods ... void checkHit(vector&lt;Real&gt;* path, vector&lt;bool&gt;* active) { for(int i = 0; i &lt; N; i++) { //Some process bool hit = ((var1 == Up)); //Like if I have never put "|| (var1 == Down));" } //... bool flag = ((var2 == Right)); } } </code></pre> <p>Hope the example is clear enough, I just simplified (a lot) the real code but it should be roughly equivalent. If it isn't clear just tell and I will gladly improve it.</p>

    1. CO`myClass obj<TypeA::Up, TypeB::Right>(...);` does not make sense.

    3. COYou mean this one : `myClass obj<Up, Right>(...);`? Well, that doesn't make sense either.

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.
