Class SharedData

java.lang.Object

io.vertx.reactivex.core.shareddata.SharedData

public class SharedData
extends Object

Shared data allows you to share data safely between different parts of your application in a safe way.

Shared data provides:

• synchronous shared maps (local)
• asynchronous maps (local or cluster-wide)
• asynchronous locks (local or cluster-wide)
• asynchronous counters (local or cluster-wide)

WARNING: In clustered mode, asynchronous maps/locks/counters rely on distributed data structures provided by the cluster manager. Beware that the latency relative to asynchronous maps/locks/counters operations can be much higher in clustered than in local mode.

Please see the documentation for more information.

NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen.

getClusterWideMap

public <K,V> void getClusterWideMap(String name,
                                    Handler<AsyncResult<AsyncMap<K,V>>> resultHandler)

Get the cluster wide map with the specified name. The map is accessible to all nodes in the cluster and data put into the map from any node is visible to to any other node.

Parameters:

name - the name of the map

resultHandler - the map will be returned asynchronously in this handler

rxGetClusterWideMap

public <K,V> Single<AsyncMap<K,V>> rxGetClusterWideMap(String name)

Get the cluster wide map with the specified name. The map is accessible to all nodes in the cluster and data put into the map from any node is visible to to any other node.

Parameters:

name - the name of the map

Returns:

getAsyncMap

public <K,V> void getAsyncMap(String name,
                              Handler<AsyncResult<AsyncMap<K,V>>> resultHandler)

Get the AsyncMap with the specified name. When clustered, the map is accessible to all nodes in the cluster and data put into the map from any node is visible to to any other node.

WARNING: In clustered mode, asynchronous shared maps rely on distributed data structures provided by the cluster manager. Beware that the latency relative to asynchronous shared maps operations can be much higher in clustered than in local mode.

Parameters:

name - the name of the map

resultHandler - the map will be returned asynchronously in this handler

rxGetAsyncMap

public <K,V> Single<AsyncMap<K,V>> rxGetAsyncMap(String name)

Get the AsyncMap with the specified name. When clustered, the map is accessible to all nodes in the cluster and data put into the map from any node is visible to to any other node.

WARNING: In clustered mode, asynchronous shared maps rely on distributed data structures provided by the cluster manager. Beware that the latency relative to asynchronous shared maps operations can be much higher in clustered than in local mode.

Parameters:

Get the AsyncMap with the specified name.

When clustered, the map is NOT accessible to all nodes in the cluster. Only the instance which created the map can put and retrieve data from this map.

Parameters:
