<DD>Checks if the item "matches" an item type, as defined in
<a href="http://www.w3.org/TR/xquery/#id-matching-item"><i>2.5.4.2
Matching an Item Type and an Item, XQuery 1.0: An XML Query Language</i></a>.
You can use this method to first check the type of the result before
calling the specific get methods.
<br>
<br>
Example -
<pre>
...
XQItemType strType = conn.createAtomicType(XQItemType.XQBASETYPE_STRING);
XQItemType nodeType = conn.createNodeType();
XQSequence result = preparedExpr.executeQuery();
while (result.next())
{
// Generic check for node..
if (result.instanceOf(nodeType))
org.w3.dom.Node node = result.getNode();
else if (result.instanceOf(strType))
String str = result.getAtomicValue();
}
</pre>
<br>
If either the type of the <code>XQItemAccessor</code> or the input
<code>XQItemType</code> is not a built-in type, then this method is
allowed to raise exception if it can NOT determine the instanceOf
relationship due to the lack of the access of
the XML schema that defines the user defined schema types if the
<code>XQMetaData.isUserDefinedXMLSchemaTypeSupported()</code> method
returns <code>false</code>.
<br>
Otherwise, this method must determine if the type of the
<code>XQItemAccessor</code> is an instance of the input
<code>XQItemType</code>. Note even if
<code>isUserDefinedXMLSchemaTypeSupported()</code> returns <code>false</code>,
an XQJ implementation may still be able to determine the instanceOf
relationship for certain cases involving user defined schema type.
For example, if the type of an <code>XQItemAccessor</code> is of
<code>mySchema:hatSize</code> sequence type and the input parameter
<code>XQItemType</code> is of <code>item()</code> sequence type,
the return value for instanceOf relationship should always be <code>true</code>
even though the XQJ implementation does not know the precise type
information of <code>mySchema:hatSize</code> type defined in XML
schema <code>'mySchema'</code>.
