Interface NetworkingService<T extends Connection>

All Known Implementing Classes:

TcpIpNetworkingService

@PrivateApi
public interface NetworkingService<T extends Connection>

Networking service, it initializes the endpoints, the acceptor and the reactive networking stack Given an EndpointQualifier an EndpointManager can be retrieved by getEndpointManager(EndpointQualifier) to create or get connections on that end.

Method Summary

Modifier and Type	Method and Description
AggregateEndpointManager	getAggregateEndpointManager() Return an aggregate endpoint which acts as a view of all endpoints merged together for reporting purposes eg.
EndpointManager<T>	getEndpointManager(EndpointQualifier qualifier) Returns the relevant EndpointManager given an EndpointQualifier On single-endpoint setups (legacy mode), then a View relevant to the requested Endpoint is returned which purely acts as a facade to hide the API differences and maintain common signatures.
IOService	getIoService() Returns the I/O Service
Networking	getNetworking() Returns the Networking engine Shared across the multiple (or not) endpoints
boolean	isLive() Flag indicating the liveness status of the Network
void	scheduleDeferred(Runnable task, long delay, TimeUnit unit) Global scheduler for all Endpoints responsible of message retransmission
void	shutdown() Shutdowns the service completely.
void	start() Starts the service, initializes its endpoints, starts threads, etc.
void	stop() Stops the service, releases its resources, stops threads, etc.

Method Detail

getIoService

IOService getIoService()

Returns the I/O Service

getNetworking

Networking getNetworking()

Returns the Networking engine Shared across the multiple (or not) endpoints

getAggregateEndpointManager

AggregateEndpointManager getAggregateEndpointManager()

Return an aggregate endpoint which acts as a view of all endpoints merged together for reporting purposes eg. Read total-connections

getEndpointManager

EndpointManager<T> getEndpointManager(EndpointQualifier qualifier)

Returns the relevant EndpointManager given an EndpointQualifier On single-endpoint setups (legacy mode), then a View relevant to the requested Endpoint is returned which purely acts as a facade to hide the API differences and maintain common signatures. eg. ProtocolType.MEMBER -> MemberViewUnifiedEndpointManager ProtocolType.CLIENT -> ClientViewUnifiedEndpointManager com.hazelcast.instance.ProtocolType#TEXT -> TextViewUnifiedEndpointManager

scheduleDeferred

void scheduleDeferred(Runnable task,
                      long delay,
                      TimeUnit unit)

Global scheduler for all Endpoints responsible of message retransmission

isLive

boolean isLive()

Flag indicating the liveness status of the Network

start

void start()

Starts the service, initializes its endpoints, starts threads, etc. After start, Endpoints becomes fully operational.

If it is already started, then this method has no effect.

Throws:

IllegalStateException - if NetworkingService is shutdown

stop

void stop()

Stops the service, releases its resources, stops threads, etc. When stopped, Endpoints can be started again using start().

This method has no effect if it is already stopped or shutdown.

Currently stop is called during the merge process to detach node from the current cluster. After node becomes ready to join to the new cluster, start is called to re-initialize the Endpoints.

shutdown

void shutdown()

Shutdowns the service completely. Endpoints and the networking endine will not be operational anymore and cannot be restarted.

This method has no effect if it is already shutdown.
