Method Detail

initializeHandlers

protected List<Tuple2<RestHandlerSpecification,org.apache.flink.shaded.netty4.io.netty.channel.ChannelInboundHandler>> initializeHandlers(CompletableFuture<String> localAddressFuture)

Description copied from class: RestServerEndpoint

This method is called at the beginning of RestServerEndpoint.start() to setup all handlers that the REST server endpoint implementation requires.

Overrides:

initializeHandlers in class WebMonitorEndpoint<DispatcherGateway>

Parameters:

localAddressFuture - future rest address of the RestServerEndpoint

Returns:

Collection of AbstractRestHandler which are added to the server endpoint

shutDownInternal

protected CompletableFuture<Void> shutDownInternal()

Description copied from class: RestServerEndpoint

Stops this REST server endpoint.

Overrides:

shutDownInternal in class WebMonitorEndpoint<DispatcherGateway>

Returns:

Future which is completed once the shut down has been finished.
