+----java.net.Socket
- public final class Socket
- extends Object
The client Socket class. It uses a SocketImpl
to implement the actual socket operations. It is done this way
so that you are able to change socket implementations depending
on the kind of firewall that is used. You can change socket
implementations by setting the SocketImplFactory.
-
Socket(String, int)
-
Creates a stream socket and connects it to the specified port on
the specified host.
-
Socket(String, int, boolean)
-
Creates a socket and connects it to the specified port on
the specified host.
-
Socket(InetAddress, int)
-
Creates a stream socket and connects it to the specified address on
the specified port.
-
Socket(InetAddress, int, boolean)
-
Creates a socket and connects it to the specified address on
the specified port.
-
close()
- Closes the socket.
-
getInetAddress()
- Gets the address to which the socket is connected.
-
getInputStream()
- Gets an InputStream for this socket.
-
getLocalPort()
- Gets the local port to which the socket is connected.
-
getOutputStream()
- Gets an OutputStream for this socket.
-
getPort()
- Gets the remote port to which the socket is connected.
-
setSocketImplFactory(SocketImplFactory)
- Sets the system's client SocketImplFactory.
-
toString()
- Converts the Socket to a String.
Socket
public Socket(String host,
int port) throws UnknownHostException, IOException
- Creates a stream socket and connects it to the specified port on
the specified host.
- Parameters:
- host - the host
- port - the port
Socket
public Socket(String host,
int port,
boolean stream) throws IOException
- Creates a socket and connects it to the specified port on
the specified host. The last argument lets you specify whether
you want a stream or datagram socket.
- Parameters:
- host - the specified host
- port - the specified port
- stream - a boolean indicating whether this is a stream
or datagram socket
Socket
public Socket(InetAddress address,
int port) throws IOException
- Creates a stream socket and connects it to the specified address on
the specified port.
- Parameters:
- address - the specified address
- port - the specified port
Socket
public Socket(InetAddress address,
int port,
boolean stream) throws IOException
- Creates a socket and connects it to the specified address on
the specified port. The last argument lets you specify whether
you want a stream or datagram socket.
- Parameters:
- address - the specified address
- port - the specified port
- stream - a boolean indicating whether this is a stream
or datagram socket
getInetAddress
public InetAddress getInetAddress()
- Gets the address to which the socket is connected.
getPort
public int getPort()
- Gets the remote port to which the socket is connected.
getLocalPort
public int getLocalPort()
- Gets the local port to which the socket is connected.
getInputStream
public InputStream getInputStream() throws IOException
- Gets an InputStream for this socket.
getOutputStream
public OutputStream getOutputStream() throws IOException
- Gets an OutputStream for this socket.
close
public synchronized void close() throws IOException
- Closes the socket.
toString
public String toString()
- Converts the Socket to a String.
- Overrides:
- toString in class Object
setSocketImplFactory
public static synchronized void setSocketImplFactory(SocketImplFactory fac) throws IOException
- Sets the system's client SocketImplFactory. The factory can
be specified only once.
- Parameters:
- fac - the desired factory
- Throws: SocketException
- If the factory is already defined.
