question: public synchronized byte [ ] toByteArray ( ) { int remaining = count ; if ( remaining == 0 ) { return EMPTY_BYTE_ARRAY ; } byte newbuf [ ] = new byte [ remaining ] ; int pos = 0 ; for ( byte [ ] buf : buffers ) { int c = Math . min ( buf . length , remaining ) ; System . arraycopy ( buf , 0 , newbuf , pos , c ) ; pos += c ; remaining -= c ; if ( remaining == 0 ) { break ; } } return newbuf ; }
target:  Gets the curent contents of this byte stream as a byte array. The result is independent of this stream.
