    <p>If it helps, the following question is in the context of a game I am building.</p> <p>In a few different places I have the following scenario. There exists a parent class, for this example called Skill, and I have a number of sub-classes implementing the methods from the parent class. There also exists another parent class that we will call Vocation. The skills need to be listed in different sub-classes of Vocation. However, those skills need to be available for anything in the game that uses any given vocation. </p> <p>My current setup is to have an Enum called Skill.Id, so that Vocation contains a collection of values from that Enum and when an entity in the game takes on that Vocation the collection is passed into another class, called SkillFactory. Skill.Id needs a new entry every time I create a new Skill sub-class, as well as a case in the switch block for the new sub-classes' constructor.</p> <p>i.e.:</p> <pre><code>//Skill.Id Enum{FireSkill,WaterSkill,etc} //SkillFactory public static Skill Create(Skill.Id id) { switch(id) { case Skill.Id.FireSkill: return new FireSkill(); //etc } } </code></pre> <p>This works perfectly fine, but using the enum and switch block as a go between feels like more overhead than I need to solve this problem. Is there a more elegant way to create instances of these Skill sub-classes, but still allows Vocation to contains a collection identifying the skills it can use?</p> <p>Edit: I am fine throwing out the enum and associated switch block, so long as Vocation can contain a collection that allows arbitrary instantiation of the Skill sub-classes.</p>

    1. COSwitch and logical if statements are extremely fast besides almost every factory implementation (I've seen) does the same thing using a switch. IMHO I wouldn't change it.

    2. COI'd agree with this, provided you aren't duplicating the switch amongst multiple routines within the type. At that point, a Dictionary lookup is often a better approach, as you can put the "switch" in a single location in the code.

    3. COthis is the fastest and the most readable way, why should find another way?

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.
