Method Details

workersCount

int workersCount()

Returns the count of threads in the pool used to process HTTP requests.

Default value is Runtime.availableProcessors().

Returns:

a workers count

port

int port()

Returns a server port to listen on with the default server socket. If port is 0 then any available ephemeral port will be used.

Additional named server socket configuration is accessible through the socket(String) and sockets() methods.

Specified by:

port in interface SocketConfiguration

Returns:

the server port of the default server socket

bindAddress

InetAddress bindAddress()

Returns local address where the server listens on with the default server socket. If null then listens an all local addresses.

Additional named server socket configuration is accessible through the socket(String) and sockets() methods.

Specified by:

bindAddress in interface SocketConfiguration

Returns:

an address to bind with the default server socket; null for all local addresses

backlog

int backlog()

Returns a maximum length of the queue of incoming connections on the default server socket.

Default value is SocketConfiguration.DEFAULT_BACKLOG_SIZE.

Additional named server socket configuration is accessible through the socket(String) and sockets() methods.

Specified by:

backlog in interface SocketConfiguration

Returns:

a maximum length of the queue of incoming connections

timeoutMillis

int timeoutMillis()

Returns a default server socket timeout in milliseconds or 0 for an infinite timeout.

Additional named server socket configuration is accessible through the socket(String) and sockets() methods.

Specified by:

timeoutMillis in interface SocketConfiguration

Returns:

a default server socket timeout in milliseconds or 0

receiveBufferSize

int receiveBufferSize()

Returns proposed value of the TCP receive window that is advertised to the remote peer on the default server socket.

If 0 then use implementation default.

Additional named server socket configuration is accessible through the socket(String) and sockets() methods.

Specified by:

receiveBufferSize in interface SocketConfiguration

Returns:

a buffer size in bytes of the default server socket or 0

socket

@Deprecated
default SocketConfiguration socket(String name)

Deprecated.

since 2.0.0, please use namedSocket(String) instead

A socket configuration of an additional named server socket.

An additional named server socket may have a dedicated Routing configured through WebServer.Builder.addNamedRouting(String, Routing).

Parameters:

name - the name of the additional server socket

Returns:

an additional named server socket configuration or null if there is no such named server socket

namedSocket

default Optional<SocketConfiguration> namedSocket(String name)

A socket configuration of an additional named server socket.

An additional named server socket may have a dedicated Routing configured through WebServer.Builder.addNamedRouting(String, Routing).

Parameters:

name - the name of the additional server socket

Returns:

an additional named server socket configuration or empty if there is no such named server socket configured

sockets

Map<String,SocketConfiguration> sockets()

A map of all the configured server sockets; that is the default server socket which is identified by the key WebServer.DEFAULT_SOCKET_NAME and also all the additional named server socket configurations.

An additional named server socket may have a dedicated Routing configured through WebServer.Builder.addNamedRouting(String, Routing).

Returns:

a map of all the configured server sockets, never null

maxShutdownTimeout

default Duration maxShutdownTimeout()

The maximum amount of time that the server will wait to shut down regardless of the value of any additionally requested quiet period.

The default implementation of this method returns Duration.ofSeconds(10L).

Returns:

the Duration to use

shutdownQuietPeriod

default Duration shutdownQuietPeriod()

The quiet period during which the webserver will wait for new incoming connections after it has been told to shut down.
