<P>
An <code>OutputStream</code> with <code>DataOutput</code>-like methods for
writing tuple fields. It is used by <code>TupleBinding</code>.
<p>This class has many methods that have the same signatures as methods in
the <CODE>DataOutput</CODE> interface. The reason this class does not
implement <CODE>DataOutput</CODE> is because it would break the interface
contract for those methods because of data format differences.</p>
<p>Signed numbers are stored in the buffer in MSB (most significant byte
first) order with their sign bit (high-order bit) inverted to cause negative
numbers to be sorted first when comparing values as unsigned byte arrays,
as done in a database. Unsigned numbers, including characters, are stored
in MSB order with no change to their sign bit. BigInteger values are stored
with a preceding length having the same sign as the value.</p>
<p>Strings and character arrays are stored either as a fixed length array of
unicode characters, where the length must be known by the application, or as
a null-terminated UTF byte array.</p>
<ul>
<li>Null strings are UTF encoded as { 0xFF }, which is not allowed in a
standard UTF encoding. This allows null strings, as distinct from empty or
zero length strings, to be represented in a tuple. Using the default
comparator, null strings will be ordered last.</li>
<li>Zero (0x0000) character values are UTF encoded as non-zero values, and
therefore embedded zeros in the string are supported. The sequence { 0xC0,
0x80 } is used to encode a zero character. This UTF encoding is the same
one used by native Java UTF libraries. However, this encoding of zero does
impact the lexicographical ordering, and zeros will not be sorted first (the
natural order) or last. For all character values other than zero, the
default UTF byte ordering is the same as the Unicode lexicographical
character ordering.</li>
</ul>
<p>Floats and doubles are stored using two different representations: sorted
representation and integer-bit (IEEE 754) representation. If you use
negative floating point numbers in a key, you should use sorted
representation; alternatively you may use integer-bit representation but you
will need to implement and configure a custom comparator to get correct
numeric ordering for negative numbers.</p>
<p>To use sorted representation use this set of methods:</p>
<ul>
<li><A HREF="../../../../com/sleepycat/bind/tuple/TupleOutput.html#writeSortedFloat(float)"><CODE>writeSortedFloat(float)</CODE></A></li>
<li><A HREF="../../../../com/sleepycat/bind/tuple/TupleInput.html#readSortedFloat()"><CODE>TupleInput.readSortedFloat()</CODE></A></li>

<li><A HREF="../../../../com/sleepycat/bind/tuple/TupleInput.html#readSortedDouble()"><CODE>TupleInput.readSortedDouble()</CODE></A></li>
</ul>
<p>To use integer-bit representation use this set of methods:</p>
