Examples of ModuleActivator

org.apache.tuscany.sca.core.ModuleActivator
ModuleActivator represents a module that plugs into the Tuscany system. Each module should provide an implementation of this interface and register the ModuleActivator implementation class by defining a file named "META-INF/services/org.apache.tuscany.core.ModuleActivator" The content of the file is the class name of the ModuleActivator implementation. The implementation class must have a no-arg constructor. The same instance will be used to invoke all the methods during different phases of the module activation. Note that the start and stop methods defined by this interface take a reference to the Tuscany SCA runtime ExtensionPointRegistry. This gives the ModuleActivator the oppotunity to add extension points to the registry as it is requested to start up and remove them when it is requested to shut down. @version $Rev: 579306 $ $Date: 2007-09-25 17:19:37 +0100 (Tue, 25 Sep 2007) $
org.jboss.gravia.runtime.ModuleActivator
Customizes the starting and stopping of a module.
{@code ModuleActivator} is an interface that may be implemented when a moduleis started or stopped. The Runtime can create instances of a module's {@code ModuleActivator} as required. If an instance's{@code ModuleActivator.start} method executes successfully, it is guaranteedthat the same instance's {@code ModuleActivator.stop} method will be calledwhen the module is to be stopped. The Runtime must not concurrently call a {@code ModuleActivator} object.
{@code ModuleActivator} is specified through the {@code Module-Activator}module header.
The specified {@code ModuleActivator} class must have a public constructorthat takes no parameters so that a {@code ModuleActivator} object can becreated by {@code Class.newInstance()}. @author thomas.diesler@jboss.com @since 27-Sep-2013 @NotThreadSafe
