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.

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.

参数:

socket - The socket to close on closing the stream.

stream - The input stream to wrap.

方法详细资料

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.

覆盖:

write 在类中 java.io.FilterOutputStream

参数:

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.

抛出:

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.

指定者:

close 在接口中 java.io.Closeable

指定者:

close 在接口中 java.lang.AutoCloseable

覆盖:

close 在类中 java.io.FilterOutputStream

抛出:

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