copied!<p>This is <a href="http://msdn.microsoft.com/en-us/library/vstudio/ms173115.aspx">constructor chaining</a>. Essentially, you're calling a different constructor before executing the contents of that constructor.</p> <pre><code>public class Foo { public Foo() : this("Hello") { Console.Write(" World!"); } public Foo(string text) { Console.Write(text); } } new Foo(); //outputs "Hello World!" </code></pre> <p>So somewhere in your <code>BarListTracker</code> there should be another constructor that takes either a <code>BarInterval[]</code> array or an <code>IEnumerable<BarInterval></code> like this:</p> <pre><code>public class BarListTracker : GotTickIndicator { public BarListTracker(BarInterval interval) : this(new BarInterval[] { interval }) { //specific initialization for this constructor } public BarListTracker(BarInterval[] intervals) { //shared initialization logic for both constructors } } </code></pre> <p>It will execute the body <code>BarListTracker(BarInterval[])</code>, <em>then</em> execute the body of <code>BarListTracker(BarInterval)</code></p> <p>This is <em>generally</em> used to reduce code duplication. If you had some initialization code for your <code>BarListTracker</code>, it makes more sense to write it in one place and share that logic with your constructors rather than rewriting it for each one.</p> <p>In addition, it lets you pass in or modify the input parameters with basic expressions. So in this case, in-line with calling the <code>BarListTracker(BarInterval[])</code> constructor, it's wrapping the single <code>BarInterval interval</code> object as an array to match the signature. Likely this is just a convenience overload to provide a simpler API for programmers who may often have only a single <code>BarInterval</code> to construct the tracker with.</p>
