Interface WatchableAsyncMap<K,V>

Type Parameters:

K - The map key type.

V - The map value type.

All Superinterfaces:

AsyncMap<K,V>

All Known Implementing Classes:

WrappedWatchableAsyncMap

public interface WatchableAsyncMap<K,V>
extends AsyncMap<K,V>

Watchable asynchronous map.

This is an extension of the AsyncMap interface that supports map key events. Types that implement this interface will trigger event handlers when data changes in the map. Note that events can be received from anywhere in the cluster, so the async map events system is distributed.

Watches a key for changes.

Parameters:

key - The key to watch.

handler - The handler to call when an event occurs.

doneHandler - An asynchronous handler to be called once the key is being watched.

watch

void watch(K key,
         MapEvent.Type event,

Parameters:

key - The key to watch.

event - The event type to watch.

handler - The handler to call when an event occurs.

watch

void watch(K key,
         MapEvent.Type event,

Watches a key for changes.

Parameters:

key - The key to watch.

event - The event type to watch.

handler - The handler to call when an event occurs.
