Constructor Detail

DefaultSharedIndexInformer

public DefaultSharedIndexInformer(Class<T> apiTypeClass,
                                  ListerWatcher<T,L> listerWatcher,
                                  long resyncPeriod,
                                  OperationContext context,
                                  Executor informerExecutor)

Method Detail

addEventHandler

public void addEventHandler(ResourceEventHandler<T> handler)

add event callback

Specified by:

addEventHandler in interface SharedInformer<T extends io.fabric8.kubernetes.api.model.HasMetadata>

Parameters:

handler - event handler

addEventHandlerWithResyncPeriod

public void addEventHandlerWithResyncPeriod(ResourceEventHandler<T> handler,
                                            long resyncPeriodMillis)

Description copied from interface: SharedInformer

Adds an event handler to the shared informer using the specified resync period. Events to a single handler are delivered sequentially, but there is no coordination between different handlers.

Specified by:

addEventHandlerWithResyncPeriod in interface SharedInformer<T extends io.fabric8.kubernetes.api.model.HasMetadata>

Parameters:

handler - the event handler

resyncPeriodMillis - the specific resync period

lastSyncResourceVersion

public String lastSyncResourceVersion()

Description copied from interface: SharedInformer

The resource version observed when last synced with the underlying store. The value returned is not synchronized with access to the underlying store and is not thread-safe.

Specified by:

lastSyncResourceVersion in interface SharedInformer<T extends io.fabric8.kubernetes.api.model.HasMetadata>

Returns:

string value or null if never synced

run

public void run()

Description copied from interface: SharedInformer

Starts the shared informer, which will be stopped when SharedInformer.stop() is called.
Only one start attempt is made - subsequent calls will not re-start the informer.
If the informer is not already running, this is a blocking call

Specified by:

run in interface SharedInformer<T extends io.fabric8.kubernetes.api.model.HasMetadata>

stop

public void stop()

Description copied from interface: SharedInformer

Stops the shared informer. The informer cannot be started again.

Specified by:

stop in interface SharedInformer<T extends io.fabric8.kubernetes.api.model.HasMetadata>

addIndexers

public void addIndexers(Map<String,Function<T,List<String>>> indexers)

Description copied from interface: SharedIndexInformer

Add indexers

Specified by:

addIndexers in interface SharedIndexInformer<T extends io.fabric8.kubernetes.api.model.HasMetadata>

Parameters:

indexers - indexers

getIndexer

public Indexer<T> getIndexer()

Description copied from interface: SharedIndexInformer

returns the internal indexer store.

Specified by:

getIndexer in interface SharedIndexInformer<T extends io.fabric8.kubernetes.api.model.HasMetadata>

Returns:

the internal indexer store

getStore

public Store<T> getStore()

Description copied from interface: SharedInformer

Return the Store associated with this informer

Specified by:

getStore in interface SharedInformer<T extends io.fabric8.kubernetes.api.model.HasMetadata>

Returns:

the store

isRunning

public boolean isRunning()

Description copied from interface: SharedInformer

Return true if the informer is running

Specified by:

isRunning in interface SharedInformer<T extends io.fabric8.kubernetes.api.model.HasMetadata>

isWatching

public boolean isWatching()

Description copied from interface: SharedInformer

Return true if the informer is actively watching
Will return false when SharedInformer.isRunning() is true when the watch needs to be re-established.

Specified by:

isWatching in interface SharedInformer<T extends io.fabric8.kubernetes.api.model.HasMetadata>

getFullResyncPeriod

public long getFullResyncPeriod()

getApiTypeClass

public Class<T> getApiTypeClass()

Description copied from interface: SharedInformer

Return the class this informer is watching

Specified by:

getApiTypeClass in interface SharedInformer<T extends io.fabric8.kubernetes.api.model.HasMetadata>
