741<h2>Class Overview</h2>
742<p itemprop="articleBody">An implementation of <code><a href="../../../../../../reference/android/support/test/espresso/IdlingResource.html">IdlingResource</a></code> that determines idleness by maintaining an internal
743 counter. When the counter is 0 - it is considered to be idle, when it is non-zero it is not
744 idle. This is very similar to the way a <code><a href="../../../../../../reference/java/util/concurrent/Semaphore.html">Semaphore</a></code> behaves.
745 <p>
746 The counter may be incremented or decremented from any thread. If it reaches an illogical state
747 (like counter less than zero) it will throw an IllegalStateException.
748 </p>
749 <p>
750 This class can then be used to wrap up operations that while in progress should block tests from
751 accessing the UI.
752 </p>
753
754 <pre>
755 <code>public interface FooServer {
756 public Foo newFoo();
757 public void updateFoo(Foo foo);
758 </code>
759
760 public DecoratedFooServer implements FooServer {
761 private final FooServer realFooServer;
762 private final CountingIdlingResource fooServerIdlingResource;
763
764 public DecoratedFooServer(FooServer realFooServer,
765 CountingIdlingResource fooServerIdlingResource) {
766 this.realFooServer = checkNotNull(realFooServer);
767 this.fooServerIdlingResource = checkNotNull(fooServerIdlingResource);
768 }
769
770 public Foo newFoo() {
771 fooServerIdlingResource.increment();
772 try {
773 return realFooServer.newFoo();
774 } finally {
775 fooServerIdlingResource.decrement();
776 }
777 }
778
779 public void updateFoo(Foo foo) {
780 fooServerIdlingResource.increment();
781 try {
782 realFooServer.updateFoo(foo);
783 } finally {
784 fooServerIdlingResource.decrement();
785 }
786 }
787 }
788 }
789 </pre>
790
791 Then in your test setup:
792 <pre>
793 <code>public void setUp() throws Exception {
794 super.setUp();
795 FooServer realServer = FooApplication.getFooServer();
796 CountingIdlingResource countingResource = new CountingIdlingResource("FooServerCalls");
797 FooApplication.setFooServer(new DecoratedFooServer(realServer, countingResource));
798 Espresso.registerIdlingResource(countingResource);
799 </code>
800 }
