question: private void createLeftOver ( ) { int lineLengthBytes = currentLastBytePos + 1 ; if ( lineLengthBytes > 0 ) { leftOver = new byte [ lineLengthBytes ] ; System . arraycopy ( data , 0 , leftOver , 0 , lineLengthBytes ) ; } else { leftOver = null ; } currentLastBytePos = - 1 ; }
target:  Creates the buffer containing any left over bytes.
