====== Generics ======

Generics are a new feature in the .NET framework, and they permit to specify also the type of a parameter for a function. Whenever you see a ''<T>'' parameter, it is a generic definition (but it could be any letter).
===== Use of generics =====

As sample how to use generics look at the [[collections:list|System.Collections.Generic.List<T>]] class:
<code visualfoxpro>local oList as List<string>

oList := List<string>{}
oList:Add( "hi girls" )
oList:Add( "hi guys" )</code>
The List class is defined as follows:
<code visualfoxpro>public class List<T> implements IList<T>, ICollection<T>, IEnumerable<T>, IEnumerable, IList, ICollection, IReadOnlyList<T>, IReadOnlyCollection<T></code>
That means that you need to define which datatype the List object should contain. In the sample before it is a string, but it can be any datatype/class.

Please note that Vulcan.NET could use methods with generic type parameters, but could not let you create them.
