org.jboss.gravia.runtime.ModuleListener
A {@code ModuleEvent} listener. {@code ModuleListener} is a listenerinterface that may be implemented by a module developer. When a {@code ModuleEvent} is fired, it is asynchronously delivered to a{@code ModuleListener}. The Runtime delivers {@code ModuleEvent} objects toa {@code ModuleListener} in order and must not concurrently call a{@code ModuleListener}.
A {@code ModuleListener} object is registered with the Runtime using the{@link ModuleContext#addModuleListener(ModuleListener)} method.{@code ModuleListener}s are called with a {@code ModuleEvent} object when amodule has been installed, resolved, started, stopped or uninstalled. @author thomas.diesler@jboss.com @since 27-Sep-2013 @see ModuleEvent @NotThreadSafe
