 <pre><a href="../../../../org/apache/felix/dm/Component.html" title="type parameter in Component">T</a>&nbsp;setImplementation(java.lang.Object&nbsp;implementation)</pre>
 <div class="block">Sets the implementation for this component. You can actually specify
  an instance you have instantiated manually, or a <code>Class</code>
  that will be instantiated using its default constructor when the
  required dependencies are resolved, effectively giving you a lazy
  instantiation mechanism.

  There are four special methods that are called when found through
  reflection to give you life cycle management options:
  <ol>
  <li><code>init()</code> is invoked after the instance has been
  created and dependencies have been resolved, and can be used to
  initialize the internal state of the instance or even to add more
  dependencies based on runtime state</li>
  <li><code>start()</code> is invoked right before the service is
  registered</li>
  <li><code>stop()</code> is invoked right after the service is
  unregistered</li>
  <li><code>destroy()</code> is invoked after all dependencies are
  removed</li>
  </ol>
  In short, this allows you to initialize your instance before it is
  registered, perform some post-initialization and pre-destruction code
  as well as final cleanup. If a method is not defined, it simply is not
  called, so you can decide which one(s) you need. If you need even more
  fine-grained control, you can register as a service state listener too.</div>
