It is used by <code>TupleBinding</code>. <p>This class has many methods that have the same signatures as methods in the <A HREF="http://java.sun.com/j2se/1.3/docs/api/java/io/DataOutput.html" title="class or interface in java.io"><CODE>DataOutput</CODE></A> interface. The reason this class does not implement <A HREF="http://java.sun.com/j2se/1.3/docs/api/java/io/DataOutput.html" title="class or interface in java.io"><CODE>DataOutput</CODE></A> 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.</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 in standard Java integer-bit representation (IEEE 754). Non-negative numbers are correctly ordered by numeric value. However, negative numbers are not correctly ordered; therefore, if you use negative floating point numbers in a key, you'll need to implement and configure a custom comparator to get correct numeric ordering.</p> <P> <P> <HR> <P> <!-- ======== NESTED CLASS SUMMARY ======== --> <!-- =========== FIELD SUMMARY =========== --> <A NAME="field_summary"><!-- --></A> <TABLE BORDER="1" WIDTH="100%"
