public class SocketOutputStream
extends 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 Details

SocketOutputStream

public SocketOutputStream(Socket socket,
 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 Details

close

public void close()
           throws IOException

Closes the stream and immediately afterward closes the referenced socket.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Overrides:

close in class FilterOutputStream

Throws:

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

write

public void write(byte[] buffer,
 int offset,
 int length)
           throws 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 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:

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