CPXOutputStream(OutputStream os)
Creates a new instance of CPXOutputStream
|
Modifier and Type | Method and Description |
---|---|
void |
close()
Closes this output stream and releases any system resources
associated with the stream.
|
void |
flush()
Flushes this output stream and forces any buffered output bytes
to be written out to the stream.
|
protected void |
processAllData() |
void |
write(byte[] b)
Writes
b.length bytes to this output stream. |
void |
write(byte[] b,
int off,
int len)
Writes
len bytes from the specified
byte array starting at offset off to
this output stream. |
void |
write(int b)
Writes the specified
byte to this output stream. |

byte
to this output stream.
The write
method of FilterOutputStream
calls the write
method of its underlying output stream,
that is, it performs out.write(b).
Implements the abstract write method of OutputStream.

b

b.length
bytes to this output stream.
The write
method of FilterOutputStream
calls its write
method of three arguments with the
arguments b
, 0
, and
b.length
.
Note that this method does not call the one-argument
write
method of its underlying stream with the single
argument b
.

len
bytes from the specified
byte
array starting at offset off
to
this output stream.
The write
method of FilterOutputStream
calls the write
method of one argument on each
byte
to output.
Note that this method does not call the write
method
of its underlying input stream with the same arguments. Subclasses
of FilterOutputStream
should provide a more efficient
implementation of this method.

public void flush() throws IOException
The flush
method of FilterOutputStream
calls the flush
method of its underlying output stream.

public void close() throws IOException
The close
method of FilterOutputStream
calls its flush
method, and then calls the
close
method of its underlying output stream.
