SocketOutputStream

SocketOutputStream(PlainSocketImpl impl)
 throws IOException

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.

Parameters:

impl - the socket output stream inplemented

getChannel

public final java.nio.channels.FileChannel getChannel()

Returns the unique FileChannel object associated with this file output stream.

The getChannel method of SocketOutputStream returns null since it is a socket based stream.

Overrides:

getChannel in class FileOutputStream

Returns:

the file channel associated with this file output stream

socketWrite0

private void socketWrite0(FileDescriptor fd,
 byte[] b,
 int off,
 int len)
 throws IOException

Writes to the socket.

Parameters:

fd - the FileDescriptor

b - the data to be written

off - the start offset in the data

len - the number of bytes that are written

IOException

---

socketWrite

private void socketWrite(byte[] b,
 int off,
 int len)
 throws IOException

Writes to the socket with appropriate locking of the FileDescriptor.

Parameters:

b - the data to be written

off - the start offset in the data

len - the number of bytes that are written

IOException

---

write

public void write(int b)
 throws IOException

Writes a byte to the socket.

Overrides:

write in class FileOutputStream

Parameters:

b - the data to be written

IOException

---

write

public void write(byte[] b)
 throws IOException

Writes the contents of the buffer b to the socket.

Overrides:

write in class FileOutputStream

Parameters:

b - the data to be written

IOException

---

write

public void write(byte[] b,
 int off,
 int len)
 throws IOException

Writes length bytes from buffer b starting at offset len.

Overrides:

write in class FileOutputStream

Parameters:

b - the data to be written

off - the start offset in the data

len - the number of bytes that are written

IOException

---

close

public void close()
 throws IOException

Description copied from class: FileOutputStream

Enabled: Closes this file output stream and releases any system resources associated with this stream. This file output stream may no longer be used for writing bytes.

If this stream has an associated channel then the channel is closed as well.

Overrides:

close in class FileOutputStream

IOException

---

finalize

protected void finalize()

Overrides finalize, the fd is closed by the Socket.

Overrides:

finalize in class FileOutputStream
