Description copied from interface: SharedData

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.

Specified by:

getClusterWideMap in interface SharedData

Parameters:

name - the name of the map

resultHandler - the map will be returned asynchronously in this handler

getLock

public void getLock(String name,
                    Handler<AsyncResult<Lock>> resultHandler)

Description copied from interface: SharedData

Get a cluster wide lock with the specified name. The lock will be passed to the handler when it is available.

Specified by:

getLock in interface SharedData

Parameters:

name - the name of the lock

resultHandler - the handler

getLockWithTimeout

public void getLockWithTimeout(String name,
