public class ItemType
extends Object

An item type, as defined in the XPath/XQuery specifications.

This class contains a number of static properties and factory methods to obtain instances representing simple item types, such as item(), node(), node kind tests such as text() and comment(), and built-in atomic types.

More complicated item types, especially those that are dependent on information in a schema, are available using factory methods on the SchemaManager object.
