java.lang.Object java.io.OutputStream java.io.FilterOutputStream org.apache.cocoon.util.BufferedOutputStream
This class is like the BufferedOutputStream
but it
extends it with a logic to count the number of bytes written to
the output stream.

len
bytes from the specified byte array
starting at offset off
to this buffered output stream.
Ordinarily this method stores bytes from the given array into this
stream's buffer, flushing the buffer to the underlying output stream as
needed. If the requested length is at least as large as this stream's
buffer, however, then this method will flush the buffer and write the
bytes directly to the underlying output stream. Thus redundant
BufferedOutputStream
s will not copy data unnecessarily.
b
- the data.off
- the start offset in the data.len
- the number of bytes to write.
