Method Detail

manage

public static void manage(io.dropwizard.lifecycle.setup.LifecycleEnvironment lifecycle,
                          Runnable startAction,
                          Runnable stopAction)

Creates a Dropwizard Managed whose start action is startAction and whose stop action is stopAction, and attaches it to the given Dropwizard lifecycle.

Useful when you have some external object that has start and stop methods, but you don't want to clutter your code by creating an anonymous inner class just to specify the start and stop actions. For example if you have an ActiveMQ PooledConnectionFactory (which has start and stop methods) you can simply call this method:

KiwiDropwizardLifecycles.manage(lifecycle, () -> factory.start(), () -> factory.stop());

To make the code cleaner, use method references:

KiwiDropwizardLifecycles.manage(lifecycle, factory::start, factory::stop);

Parameters:

lifecycle - the lifecycle to manage

startAction - the action to run when Dropwizard starts the application

stopAction - the action to run when Dropwizard stops the application
