Method Details
-
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 classAbstractLifecycleComponent
-
doStop
protected void doStop()Description copied from class:AbstractLifecycleComponent
Stop this component. Typically that means doing the reverse of whateverAbstractLifecycleComponent.doStart()
does.This method is called while synchronized on
AbstractLifecycleComponent.lifecycle
. It is only called once in the lifetime of a component, after callingAbstractLifecycleComponent.doStart()
, although it will not be called at all if this component did not successfully start.- Specified by:
doStop
in classAbstractLifecycleComponent
-
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 classAbstractLifecycleComponent

applyClusterState
Description copied from interface:ClusterStateApplier
Called when a new cluster state (ClusterChangedEvent.state()
needs to be applied. The cluster state to be applied is already committed when this method is called, so an applier must therefore be prepared to deal with any state it receives without throwing an exception. Throwing an exception from an applier is very bad because it will stop the application of this state before it has reached all the other appliers, and will likely result in another attempt to apply the same (or very similar) cluster state which might continue until this node is removed from the cluster.Cluster states are applied one-by-one which means they can be a performance bottleneck. Implementations of this method should therefore be fast, so please consider forking work into the background rather than doing everything inline.
