Method Detail

setLifecycleTimeout

public void setLifecycleTimeout(java.time.Duration timeout)

Change the lifecycle timeout applied to the shutdown() operation (as this can only be called AFTER the NettyContext has been "started").

Parameters:

timeout - the new timeout to apply on shutdown.

getContext

public NettyContext getContext()

Get the NettyContext wrapped by this facade.

Returns:

the original NettyContext.

getPort

public int getPort()

Return this server's port.

Returns:

The port the server is bound to.

getHost

public String getHost()

Return the server's host String. That is, the hostname or in case the server was bound to a literal IP adress, the IP string representation (rather than performing a reverse-DNS lookup).

Returns:

the host string, without reverse DNS lookup

NettyContext.address(), InetSocketAddress.getHostString()

installShutdownHook

public void installShutdownHook()

Install a JVM shutdown hook that will shutdown this BlockingNettyContext if the JVM is terminated externally.

The hook is removed if shutdown manually, and subsequent calls to this method are no-op.

removeShutdownHook

public boolean removeShutdownHook()

Remove a JVM shutdown hook if one was installed by this BlockingNettyContext.

Returns:

true if there was a hook and it was removed, false otherwise.

getShutdownHook

protected Thread getShutdownHook()

Returns:

the current JVM shutdown hook. Shouldn't be passed to users.

shutdown

public void shutdown()

Shut down the NettyContext and wait for its termination, up to the lifecycle timeout.

shutdownFromJVM

protected void shutdownFromJVM()
