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 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.
