CompletableFuture java8 class provides functional operations and promotes an asynchronous event-driven model. + +In such model, you can use the new dm-lambda library to add dependencies on asynchronous events using the standard JDK CompletableFuture class. + +In this example, the Activator first defines a PageLink component that depends on a LogService. +The PageLink is initialized with the Felix web site URL and from the PageLinkImpl.init() method, the Felix web page is asynchronously downloaded, +using a CompletableFuture. The CF is then added as a "FutureDependency" in the PageLinkImpl.init() method. +And when the CF completes, the PageLinkImpl.start() callback is invoked and the service is registered. +The Activator is then getting injected with the PageLink service, and displays the links (hrefs) found from the Felix web site. \ No newline at end of file Added: felix/sandbox/pderop/dependencymanager-lambda/org.apache.felix.dependencymanager.lambda.samples/src/org/apache/felix/dm/lambda/samples/hello/Activator.java URL: http://svn.apache.org/viewvc/felix/sandbox/pderop/dependencymanager-lambda/org.apache.felix.dependencymanager.lambda.samples/src/org/apache/felix/dm/lambda/samples/hello/Activator.java?rev=1727487&view=auto ============================================================================== --- felix/sandbox/pderop/dependencymanager-lambda/org.apache.felix.dependencymanager.lambda.samples/src/org/apache/felix/dm/lambda/samples/hello/Activator.java (added) +++ felix/sandbox/pderop/dependencymanager-lambda/org.apache.felix.dependencymanager.lambda.samples/src/org/apache/felix/dm/lambda/samples/hello/Activator.java Fri Jan 29 06:50:09 2016 @@ -0,0 +1,49 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.
