<P>
|
|
An <code>InputStream</code> with <code>DataInput</code>-like methods for
|
|
reading tuple fields. 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/1.5.0/docs/api/java/io/DataInput.html" title="class or interface in java.io"><CODE>DataInput</CODE></A> interface. The reason this class does not
|
|
implement <A HREF="http://java.sun.com/j2se/1.5.0/docs/api/java/io/DataInput.html" title="class or interface in java.io"><CODE>DataInput</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. 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>TupleOutput.writeSortedFloat(float)</CODE></A></li>

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