public void write(int b) throws java.io.IOException
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.
write

b
- the byte
.
java.io.IOException
- if an I/O error occurs.public void write(byte[] b) throws java.io.IOException
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
.

- the data to be written.
java.io.IOException
- if an I/O error occurs.FilterOutputStream.write(byte[], int, int)
public void write(byte[] b, int off, int len) throws java.io.IOException
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.
