resolveHosts

public List<TransportAddress> resolveHosts(List<String> hosts)

Specified by:

doStart

protected void doStart()

Description copied from class: AbstractLifecycleComponent

Start this component. Typically that means doing things like launching background processes and registering listeners on other components. Other components have been initialized by this point, but may not yet be started.

If this method throws an exception then the startup process will fail, but this component will not be stopped before it is closed.

This method is called while synchronized on AbstractLifecycleComponent.lifecycle. It is only called once in the lifetime of a component, although it may not be called at all if the startup process encountered some kind of fatal error, such as the failure of some other component to initialize or start.

Specified by:

doStart in class AbstractLifecycleComponent

doStop

protected void doStop()

Description copied from class: AbstractLifecycleComponent

Stop this component. Typically that means doing the reverse of whatever AbstractLifecycleComponent.doStart() does.

This method is called while synchronized on AbstractLifecycleComponent.lifecycle. It is only called once in the lifetime of a component, after calling AbstractLifecycleComponent.doStart(), although it will not be called at all if this component did not successfully start.

Specified by:

doStop in class AbstractLifecycleComponent

doClose

protected void doClose()

Description copied from class: AbstractLifecycleComponent

Close this component. Typically that means doing the reverse of whatever happened during initialization, such as releasing resources acquired there.

This method is called while synchronized on AbstractLifecycleComponent.lifecycle. It is called once in the lifetime of a component. If the component was started then it will be stopped before it is closed, and once it is closed it will not be started or stopped.

Specified by:

doClose in class AbstractLifecycleComponent

resolveConfiguredHosts

public void resolveConfiguredHosts(Consumer<List<TransportAddress>> consumer)

Description copied from interface: ConfiguredHostsResolver

Attempt to resolve the configured hosts list to a list of transport addresses.

Specified by:

resolveConfiguredHosts in interface ConfiguredHostsResolver

Parameters:

consumer - Consumer for the resolved list. May not be called if an error occurs or if another resolution attempt is in progress.
