<p>What does "=>" mean in the example below?</p> <pre class="prettyprint"><code>trait MyService[E <: Entity[ID]] extends Management { this: Repository[E] => // some code } </code></pre>

<p>In this example it means that <code>this</code> has to be of the type <code>Repository[E]</code>. That means that the trait <code>MyService</code> can only be mixed into classes extending <code>Repository[E]</code>.</p>
