Moreover, it is guaranteed that <em>all writes performed by this class will be multiples of the given buffer size</em>. If, for instance, you use the default buffer size, writes will be performed on the underlying input stream in multiples of 16384 bytes. This is very important on operating systems that optimise disk reads on disk block boundaries.<P><P><HR><P><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE
