/**
* Local maps can be used to share data safely in a single Vert.x instance.
*
* By default the map allows immutable keys and values.
* Custom keys and values should implement {@link io.vertx.core.shareddata.Shareable} interface. The map returns their copies.
*
* This ensures there is no shared access to mutable state from different threads (e.g. different event loops) in the
* Vert.x instance, and means you don't have to protect access to that state using synchronization or locks.
*
*
* Since the version 3.4, this class extends the interface. However some methods are only accessible in Java.
*
*
* NOTE: This class has been automatically generated from the {@link io.vertx.core.shareddata.LocalMap original} non RX-ified interface using Vert.x codegen.
