SocketOutputStream

• java.lang.Object
  • java.io.OutputStream
    • java.io.FileOutputStream

Fields Summary
private PlainSocketImpl	impl
private byte[]	temp
private Socket	socket
private boolean	closing Closes the stream.

Constructors Summary
SocketOutputStream(PlainSocketImpl impl) Creates a new SocketOutputStream. Can only be called by a Socket. This method needs to hang on to the owner Socket so that the fd will not be closed. param impl the socket output stream inplemented super(impl.getFileDescriptor()); this.impl = impl; socket = impl.getSocket();

Methods Summary
public void	close() // Prevent recursion. See BugId 4484411 if (closing) return; closing = true; if (socket != null) { if (!socket.isClosed()) socket.close(); } else impl.close(); closing = false;
protected void	finalize() Overrides finalize, the fd is closed by the Socket.
public final java.nio.channels.FileChannel	getChannel() Returns the unique {@link java.nio.channels.FileChannel FileChannel} object associated with this file output stream. The getChannel method of SocketOutputStream returns null since it is a socket based stream. return the file channel associated with this file output stream since 1.4 spec JSR-51 return null;
private static native void	init() Perform class load-time initializations.
private void	socketWrite(byte[] b, int off, int len) Writes to the socket with appropriate locking of the FileDescriptor. param b the data to be written param off the start offset in the data param len the number of bytes that are written exception IOException If an I/O error has occurred. if (len <= 0 || off < 0 || off + len > b.length) { if (len == 0) { return; } throw new ArrayIndexOutOfBoundsException(); } FileDescriptor fd = impl.acquireFD(); try { socketWrite0(fd, b, off, len); } catch (SocketException se) { if (se instanceof sun.net.ConnectionResetException) { impl.setConnectionResetPending(); se = new SocketException("Connection reset"); } if (impl.isClosedOrPending()) { throw new SocketException("Socket closed"); } else { throw se; } } finally { impl.releaseFD(); }
private native void	socketWrite0(java.io.FileDescriptor fd, byte[] b, int off, int len) Writes to the socket. param fd the FileDescriptor param b the data to be written param off the start offset in the data param len the number of bytes that are written exception IOException If an I/O error has occurred.
public void	write(int b) Writes a byte to the socket. param b the data to be written exception IOException If an I/O error has occurred. temp[0] = (byte)b; socketWrite(temp, 0, 1);
public void	write(byte[] b) Writes the contents of the buffer b to the socket. param b the data to be written exception SocketException If an I/O error has occurred. socketWrite(b, 0, b.length);
public void	write(byte[] b, int off, int len) Writes length bytes from buffer b starting at offset len. param b the data to be written param off the start offset in the data param len the number of bytes that are written exception SocketException If an I/O error has occurred. socketWrite(b, off, len);
