Method Details

setRouteProviders

public void setRouteProviders(List<NettyRouteProvider> routeProviders)

start

public void start()
           throws WebServerException

Description copied from interface: WebServer

Starts the web server. Calling this method on an already started server has no effect.

Specified by:

start in interface WebServer

Throws:

WebServerException - if the server cannot be started

getStartedLogMessage

protected String getStartedLogMessage()

shutDownGracefully

public void shutDownGracefully(GracefulShutdownCallback callback)

Description copied from interface: WebServer

Initiates a graceful shutdown of the web server. Handling of new requests is prevented and the given callback is invoked at the end of the attempt. The attempt can be explicitly ended by invoking WebServer.stop(). The default implementation invokes the callback immediately with GracefulShutdownResult.IMMEDIATE, i.e. no attempt is made at a graceful shutdown.

Specified by:

shutDownGracefully in interface WebServer

Parameters:

callback - the callback to invoke when the graceful shutdown completes

stop

public void stop()
          throws WebServerException

Description copied from interface: WebServer

Stops the web server. Calling this method on an already stopped server has no effect.

stop in interface WebServer

Throws:

WebServerException - if the server cannot be stopped
