Field Summary

private GZIPInputStream	inputStream Wrapper for the socket input stream.
private GZIPOutputStream	outputStream Wrapper for the socket output stream.

Constructor Summary

GzipSocket(String host, int port)
Creates a socket which connects to the given host on the given port.

Method Summary

void	close()
InputStream	getInputStream() Overrides the base class method for returning the input stream for this socket and returns instead the gzip-based wrapper.
OutputStream	getOutputStream() Overrides the base class method for returning the output stream for this socket and returns instead the gzip-based wrapper.
void	shutdownInput()
void	shutdownOutput()

Wrapper for the socket output stream.

Constructor Detail

GzipSocket

public GzipSocket(String host,
                  int port)
           throws UnknownHostException,
                  IOException

Creates a socket which connects to the given host on the given port.

Parameters:

host - Host to connect to

port - Port to connect to

Throws:

UnknownHostException - if host name or IP is wrong

IOException - if I/O errors occur when connecting

Method Detail

close

public void close()
           throws IOException

Overrides:

close in class Socket

Throws:

IOException

getInputStream

public InputStream getInputStream()
                           throws IOException

Overrides the base class method for returning the input stream for this socket and returns instead the gzip-based wrapper. Note that this is a lazy evaluation function. NOTE: The GzipInputStream blocks on creation to read the header so this function actually blocks until data is available over the wire!

Overrides:

getInputStream in class Socket

Returns:

wrapper for the base class input stream

Throws:

IOException - if I/O errors occur

getOutputStream

public OutputStream getOutputStream()
                             throws IOException

Overrides the base class method for returning the output stream for this socket and returns instead the gzip-based wrapper.

Overrides:

getOutputStream in class Socket

Returns:

wrapper for the base class output stream

Throws:

IOException - if I/O errors occur

See Also:

outputStream

shutdownInput

public void shutdownInput()
                   throws IOException

Overrides:

shutdownInput in class Socket

Throws:

IOException

shutdownOutput

public void shutdownOutput()
                    throws IOException

Overrides:

shutdownOutput in class Socket

Throws:

IOException
