package org.apache.commons.net.io;
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.

public class SocketOutputStream extends FilterOutputStream
    private final Socket __socket;

    
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.
    public SocketOutputStream(Socket socketOutputStream stream)
    {
        super(stream);
         = socket;
    }


    
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.

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.
    @Override
    public void write(byte buffer[], int offsetint lengththrows IOException
    {
        .write(bufferoffsetlength);
    }


    
Closes the stream and immediately afterward closes the referenced socket.

Throws:
java.io.IOException If there is an error in closing the stream or socket.
    @Override
    public void close() throws IOException
    {
        super.close();
        .close();
    }
