public class SocketOutputStream

extends java.io.FilterOutputStream

This class wraps an output stream, storing a reference to its originating socket. When the stream is closed, it will also close the socket immediately afterward. This class is useful for situations where you are dealing with a stream originating from a socket, but do not have a reference to the socket, and want to make sure it closes when the stream closes.

Constructor Summary

SocketOutputStream(java.net.Socket socket, java.io.OutputStream stream)
Creates a SocketOutputStream instance wrapping an output stream and storing a reference to a socket that should be closed on closing the stream.

Method Summary

void	close() Closes the stream and immediately afterward closes the referenced socket.
void	write(byte[] buffer, int offset, int length) Writes a number of bytes from a byte array to the stream starting from a given offset.

Constructor Detail

SocketOutputStream

public SocketOutputStream(java.net.Socket socket,
                          java.io.OutputStream stream)

Creates a SocketOutputStream instance wrapping an output stream and storing a reference to a socket that should be closed on closing the stream.

Parameters:

socket - The socket to close on closing the stream.

stream - The input stream to wrap.

Method Detail

write

public void write(byte[] buffer,
                  int offset,
                  int length)
           throws java.io.IOException

Writes a number of bytes from a byte array to the stream starting from a given offset. This method bypasses the equivalent method in FilterOutputStream because the FilterOutputStream implementation is very inefficient.

Overrides:

write in class java.io.FilterOutputStream

Parameters:

buffer - The byte array to write.

offset - The offset into the array at which to start copying data.

length - The number of bytes to write.

Throws:

java.io.IOException - If an error occurs while writing to the underlying stream.

close

public void close()
           throws java.io.IOException

Closes the stream and immediately afterward closes the referenced socket.

Overrides:

close in class java.io.FilterOutputStream

Throws:

java.io.IOException - If there is an error in closing the stream or socket.
