Known Direct Subclasses |
The base class for all output streams. An output stream is a means of writing
data to a target in a byte-wise manner. Most output streams expect the
flush()
method to be called before closing the stream, to ensure all
data is actually written through.
This abstract class does not provide a fully working implementation, so it
needs to be subclassed, and at least the write(int)
method needs to
be overridden. Overriding some of the non-abstract methods is also often
advised, since it might result in higher efficiency.
Many specialized output streams for purposes like writing to a file already exist in this package.

Closes this stream. Implementations of this method should free any resources used by the stream. This implementation does nothing.
IOException | if an error occurs while closing this stream. |
---|
Flushes this stream. Implementations of this method should ensure that any buffered data is written out. This implementation does nothing.
IOException | if an error occurs while flushing this stream. |
---|
Writes count
bytes from the byte array buffer
starting at
position offset
to this stream.
buffer | the buffer to be written. |
---|---|
offset | the start position in buffer from where to get bytes. |
count | the number of bytes from buffer to write to this
stream. |
IOException | if an error occurs while writing to this stream. |
---|---|
IndexOutOfBoundsException | if offset < 0 or count < 0 , or if
offset + count is bigger than the length of
buffer .
|
Writes the entire contents of the byte array buffer
to this
stream.
buffer | the buffer to be written. |
---|
IOException | if an error occurs while writing to this stream. |
---|
Writes a single byte to this stream. Only the least significant byte of
the integer oneByte
is written to the stream.
oneByte | the byte to be written. |
---|
IOException | if an error occurs while writing to this stream. |
