- Direct Known Subclasses:
SSLServerSocketFactory
Like socket factories, server Socket factory instances have methods used to create sockets. There is also an environment specific default server socket factory; frameworks will often use their own customized factory.

Method Details
-
getDefault
Returns a copy of the environment's default socket factory.- Returns:
- the
ServerSocketFactory
-
createServerSocket
Returns an unbound server socket. The socket is configured with the socket options (such as accept timeout) given to this factory.- Returns:
- the unbound socket
- Throws:
IOException
- if the socket cannot be created- See Also:
-
createServerSocket
Returns a server socket bound to the specified port. The socket is configured with the socket options (such as accept timeout) given to this factory.If there is a security manager, its
checkListen
method is called with theport
argument as its argument to ensure the operation is allowed. This could result in a SecurityException.- Parameters:
port
- the port to listen to- Returns:
- the
ServerSocket
- Throws:
IOException
- for networking errorsSecurityException
- if a security manager exists and itscheckListen
method doesn't allow the operation.IllegalArgumentException
- if the port parameter is outside the specified range of valid port values, which is between 0 and 65535, inclusive.- See Also:
-
createServerSocket
Returns a server socket bound to the specified port, and uses the specified connection backlog. The socket is configured with the socket options (such as accept timeout) given to this factory.The
backlog
argument must be a positive value greater than 0. If the value passed if equal or less than 0, then the default value will be assumed.If there is a security manager, its
checkListen
method is called with theport
argument as its argument to ensure the operation is allowed. This could result in a SecurityException.- Parameters:
port
- the port to listen tobacklog
- how many connections are queued- Returns:
- the
ServerSocket
- Throws:
IOException
- for networking errorsSecurityException
- if a security manager exists and itscheckListen
method doesn't allow the operation.IllegalArgumentException
- if the port parameter is outside the specified range of valid port values, which is between 0 and 65535, inclusive.- See Also:
-
createServerSocket
public abstract ServerSocket createServerSocket(int port, int backlog, InetAddress ifAddress) throws IOException Returns a server socket bound to the specified port, with a specified listen backlog and local IP.The
ifAddress
argument can be used on a multi-homed host for aServerSocket
that will only accept connect requests to one of its addresses. IfifAddress
is null, it will accept connections on all local addresses. The socket is configured with the socket options (such as accept timeout) given to this factory.The
backlog
argument must be a positive value greater than 0. If the value passed if equal or less than 0, then the default value will be assumed.If there is a security manager, its
checkListen
method is called with theport
argument as its argument to ensure the operation is allowed. This could result in a SecurityException.- Parameters:
port
- the port to listen tobacklog
- how many connections are queuedifAddress
- the network interface address to use- Returns:
- the
ServerSocket
- Throws:
IOException
- for networking errorsSecurityException
- if a security manager exists and itscheckListen
method doesn't allow the operation.IllegalArgumentException
- if the port parameter is outside the specified range of valid port values, which is between 0 and 65535, inclusive.- See Also:
