Class java.net.SocketImpl 

java.lang.Object
|
   +----java.net.SocketImpl
public class SocketImpl
extends Object
This is the Socket implementation class. It is an abstract class that must be subclassed to provide an actual implementation.

Variable Index

o address
The internet address where the socket will make a connection.
o fd
The file descriptor object
o localport
o port
The port where the socket will make a connection.

Constructor Index

o SocketImpl()

Method Index

o accept(SocketImpl)
Accepts a connection.
o available()
Returns the number of bytes that can be read without blocking.
o bind(InetAddress, int)
Binds the socket to the specified port on the specified host.
o close()
Closes the socket.
o connect(InetAddress, int)
Connects the socket to the specified address on the specified port.
o connect(String, int)
Connects the socket to the specified port on the specified host.
o create(boolean)
Creates a socket with a boolean that specifies whether this is a stream socket or a datagram socket.
o getFileDescriptor()
o getInetAddress()
o getInputStream()
Gets an InputStream for this socket.
o getLocalPort()
o getOutputStream()
Gets an OutputStream for this socket.
o getPort()
o listen(int)
Specify to the system how many connection requests the system will queue up while waiting for the SocketImpl to execute accept().
o toString()
Returns the address and port of this Socket as a String.

Variables

o fd 
protected FileDescriptor fd
The file descriptor object
o address 
protected InetAddress address
The internet address where the socket will make a connection.
o port 
protected int port
The port where the socket will make a connection.
o localport 
protected int localport

Constructors

o SocketImpl 
public SocketImpl()

Methods

o create 
protected abstract void create(boolean stream) throws IOException
Creates a socket with a boolean that specifies whether this is a stream socket or a datagram socket.
Parameters:
stream - a boolean indicating whether this is a stream or datagram socket
o connect 
protected abstract void connect(String host,
                                  int port) throws IOException
Connects the socket to the specified port on the specified host.
Parameters:
host - the specified host of the connection
port - the port where the connection is made
o connect 
protected abstract void connect(InetAddress address,
                                  int port) throws IOException
Connects the socket to the specified address on the specified port.
Parameters:
address - the specified address of the connection
port - the specified port where connection is made
o bind 
protected abstract void bind(InetAddress host,
                               int port) throws IOException
Binds the socket to the specified port on the specified host.
Parameters:
host - the host
port - the port
o listen 
protected abstract void listen(int backlog) throws IOException
Specify to the system how many connection requests the system will queue up while waiting for the SocketImpl to execute accept().
Parameters:
backlog - the number of queued connect requests pending accept
o accept 
protected abstract void accept(SocketImpl s) throws IOException
Accepts a connection.
Parameters:
s - the accepted connection
o getInputStream 
protected abstract InputStream getInputStream() throws IOException
Gets an InputStream for this socket.
o getOutputStream 
protected abstract OutputStream getOutputStream() throws IOException
Gets an OutputStream for this socket.
o available 
protected abstract int available() throws IOException
Returns the number of bytes that can be read without blocking.
o close 
protected abstract void close() throws IOException
Closes the socket.
o getFileDescriptor 
protected FileDescriptor getFileDescriptor()
o getInetAddress 
protected InetAddress getInetAddress()
o getPort 
protected int getPort()
o getLocalPort 
protected int getLocalPort()
o toString 
public String toString()
Returns the address and port of this Socket as a String.
Overrides:
toString in class Object
