WanPublisher (Hazelcast Root 5.4.0-SNAPSHOT API)

Type Parameters:

T - type of event data that the publisher will publish
```
public interface WanPublisher<T>
```
This interface offers the implementation of different kinds of replication techniques like TCP, UDP or maybe even an JMS based service. Implementations of this interface represent a replication target, normally another Hazelcast cluster only reachable over a Wide Area Network (WAN). The publisher may implement HazelcastInstanceAware if it needs a reference to the instance on which it is being run.

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`void`	`doPrepublicationChecks()`	Performs pre-publication checks (e.g.
`void`	`init(WanReplicationConfig wanReplicationConfig, AbstractWanPublisherConfig publisherConfig)`	Initializes the publisher.
`void`	`publishReplicationEvent(WanEvent<T> eventObject)`	Publish the `eventObject` WAN replication event.
`void`	`publishReplicationEventBackup(WanEvent<T> eventObject)`	Publish the `eventObject` WAN replication event backup.
`default void`	`reset()`	Resets the publisher (e.g.
`void`	`shutdown()`	Closes the publisher and its internal connections and shuts down other internal states.

- Method Detail
  - init
```
void init(WanReplicationConfig wanReplicationConfig,
          AbstractWanPublisherConfig publisherConfig)
```
    Initializes the publisher.
    
    Parameters:
    
    wanReplicationConfig - WanReplicationConfig instance
    
    publisherConfig - AbstractWanPublisherConfig instance
  - shutdown
```
void shutdown()
```
    Closes the publisher and its internal connections and shuts down other internal states. Signals the publisher to shut down and clean up its resources. The method does not necessarily block until the publisher has shut down.
  - reset
```
default void reset()
```
    Resets the publisher (e.g. before split-brain merge).
  - doPrepublicationChecks
```
void doPrepublicationChecks()
```
    Performs pre-publication checks (e.g. enforcing invariants). Invoked before publishReplicationEvent(WanEvent) and publishReplicationEventBackup(WanEvent).
  - publishReplicationEvent
```
void publishReplicationEvent(WanEvent<T> eventObject)
```
    Publish the eventObject WAN replication event.
    
    Parameters:
    
    eventObject - the replication event
  - publishReplicationEventBackup
```
void publishReplicationEventBackup(WanEvent<T> eventObject)
```
    Publish the eventObject WAN replication event backup.
    
    Parameters:
    
    eventObject - the replication backup event
