Detailed Description

This class is the base of all streaming socket implementation classes. Streaming sockets are wrapped by two classes,

ServerSocket

and

Socket

at the server and client end of a connection. At the server, there are two types of sockets engaged in communication, the

ServerSocket

on a well known port (referred to as listener) used to establish a connection and the resulting

Socket

(referred to as host).

Member Function Documentation

◆ available()

abstract int java.net.SocketImpl.available ( ) throws IOException

abstractprotected

Returns the available number of bytes which are readable from this socket without blocking.

Returns: the number of bytes that may be read without blocking.

Exceptions

IOException if an error occurs while reading the number of bytes.

◆ bind()

abstract void java.net.SocketImpl.bind	(	InetAddress	address,
		int	port
	)		throws IOException

abstractprotected

Binds this socket to the specified local host address and port number.

Parameters

address	the local machine address to bind this socket to.
port	the port on the local machine to bind this socket to.

Exceptions

IOException if an error occurs while binding this socket.

◆ close()

abstract void java.net.SocketImpl.close ( ) throws IOException

abstractprotected

Closes this socket. This makes later access invalid.

Exceptions

IOException if an error occurs while closing this socket.

◆ connect() [1/3]

abstract void java.net.SocketImpl.connect	(	String	host,
		int	port
	)		throws IOException

abstractprotected

Connects this socket to the specified remote host and port number.

Parameters

host	the remote host this socket has to be connected to.
port	the remote port on which this socket has to be connected.

Exceptions

IOException if an error occurs while connecting to the remote host.

◆ connect() [2/3]

abstract void java.net.SocketImpl.connect	(	InetAddress	address,
		int	port
	)		throws IOException

abstractprotected

Connects this socket to the specified remote host address and port number.

Parameters

address	the remote host address this socket has to be connected to.
port	the remote port on which this socket has to be connected.

Exceptions

IOException if an error occurs while connecting to the remote host.

◆ connect() [3/3]

abstract void java.net.SocketImpl.connect	(	SocketAddress	remoteAddr,
		int	timeout
	)		throws IOException

abstractprotected

Connects this socket to the remote host address and port number specified by the

SocketAddress

object with the given timeout. This method will block indefinitely if the timeout is set to zero.

Parameters

remoteAddr	the remote host address and port number to connect to.
timeout	the timeout value in milliseconds.

Exceptions

IOException if an error occurs while connecting.

◆ create()

abstract void java.net.SocketImpl.create ( ) throws IOException

abstractprotected

Creates a new unconnected socket. The argument

isStreaming

defines whether the new socket is a streaming or a datagram socket.

Parameters

isStreaming defines whether the type of the new socket is streaming or datagram.

Exceptions

IOException if an error occurs while creating the socket.

◆ getInetAddress()

InetAddress java.net.SocketImpl.getInetAddress ( )

inlineprotected

Gets the remote address this socket is connected to.

Returns: the remote address of this socket.

◆ getInputStream()

abstract InputStream java.net.SocketImpl.getInputStream ( ) throws IOException

abstractprotected

Gets the input stream of this socket.

Returns: the input stream of this socket.

Exceptions

IOException if an error occurs while accessing the input stream.

◆ getLocalPort()

int java.net.SocketImpl.getLocalPort ( )

inlineprotected

Gets the local port number of this socket. The field is initialized to

-1

and upon demand will go to the IP stack to get the bound value. See the class comment for the context of the local port.

Returns: the local port number this socket is bound to.

◆ getOutputStream()

abstract OutputStream java.net.SocketImpl.getOutputStream ( ) throws IOException

abstractprotected

Gets the output stream of this socket.

Returns: the output stream of this socket.

Exceptions

IOException if an error occurs while accessing the output stream.

◆ getPort()

int java.net.SocketImpl.getPort ( )

inlineprotected

Gets the remote port number of this socket. This value is not meaningful when this instance is wrapped by a

ServerSocket

.

Returns: the remote port this socket is connected to.

◆ setPerformancePreferences()

void java.net.SocketImpl.setPerformancePreferences	(	int	connectionTime,
		int	latency,
		int	bandwidth
	)

inlineprotected

Sets performance preference for connection time, latency and bandwidth. Does nothing by default.

Parameters

connectionTime	the importance of connect time.
latency	the importance of latency.
bandwidth	the importance of bandwidth.

◆ shutdownInput()

void java.net.SocketImpl.shutdownInput ( ) throws IOException

inlineprotected

Closes the input channel of this socket.

This default implementation always throws an IOException to indicate that the subclass should have overridden this method.

Exceptions

IOException always because this method should be overridden.

◆ shutdownOutput()

void java.net.SocketImpl.shutdownOutput ( ) throws IOException

inlineprotected

Closes the output channel of this socket.

This default implementation always throws an IOException to indicate that the subclass should have overridden this method.

Exceptions

IOException always because this method should be overridden.

◆ toString()

String java.net.SocketImpl.toString ( )

inline

Returns a string containing a concise, human-readable description of the socket.

Returns: the textual representation of this socket.

Member Data Documentation

◆ address

InetAddress java.net.SocketImpl.address

protected

The remote address this socket is connected to.

◆ localport

int java.net.SocketImpl.localport

protected

The local port this socket is connected to.

◆ port

int java.net.SocketImpl.port

protected

The remote port this socket is connected to.
