<h1>Using TA Collections Directly</h1>
<p>You can use the transparent activation aware collections directly in your code. They behavior is the same as the <span class="PrimaryPlattform">.NET</span>-collections. Here are a few tips:</p>
<ul>
<li value="1">Prefer the collection-interfaces over the concrete classes in your field, parameter and return-type declarations. For example declare a field as a
<span MadCap:conditions="Primary..NET">IList<T> instead of a List<T></span></li>
<li value="2">Maybe it useful to create a collection factory in your code. Then you have only one play in your code which decides which classes are used. So it easy to replace the implementations.</li>
</ul>
<p>An example:</p>
<div class="codesnippet" MadCap:conditions="Primary.c#">
<pre class="prettyprint" xml:space="preserve">public class Team : ActivatableBase
{
private readonly IList<Pilot> pilots = new ActivatableList<Pilot>();
public void Add(Pilot pilot)
{
Activate(ActivationPurpose.Write);
pilots.Add(pilot);
}
public ICollection<Pilot> Pilots
{
get
{
Activate(ActivationPurpose.Read);
return pilots;
}
}
}</pre>
<div class="codesnippet-meta">Team.cs: Using the activation aware collections
<div class="codedownload"><a href="../../../../CodeExamples/ta/collections/Example-ta-collections-csharp.zip" class="codedownload" MadCap:conditions="Primary.Online">Download Code</a></div><div class="codedownload copylink-marker" MadCap:conditions="Primary.Online"><a href="#copy">Copy Code</a></div></div>
</div>
<div class="codesnippet" MadCap:conditions="Primary.VB.NET">
<pre class="prettyprint lang-vb" MadCap:conditions="Primary.Online" xml:space="preserve">Public Class Team
Inherits ActivatableBase
Private ReadOnly m_pilots As IList(Of Pilot) = New ActivatableList(Of Pilot)()
Public Sub Add(ByVal pilot As Pilot)
Activate(ActivationPurpose.Write)
m_pilots.Add(pilot)
End Sub
Public ReadOnly Property Pilots() As ICollection(Of Pilot)
Get
Activate(ActivationPurpose.Read)
Return m_pilots
End Get
End Property
End Class</pre>
<div class="codesnippet-meta">Team.vb: Using the activation aware collections
<div class="codedownload"><a href="../../../../CodeExamples/ta/collections/Example-ta-collections-vb.zip" class="codedownload" MadCap:conditions="Primary.Online">Download Code</a></div><div class="codedownload copylink-marker" MadCap:conditions="Primary.Online"><a href="#copy">Copy Code</a></div></div>
</div>
<p>Currently these collections are available:</p>
<ul MadCap:conditions="Primary..NET">
<li value="1">ActivatableList<T>: An activatable version of the List<T>-class</li>
<li value="2">ActivatableDictionary<T>: An activatable version of the Dictionary<T></li>
