public class ItemType
extends java.lang.Object
This class contains a number of static properties
to obtain instances representing simple item types, such as
item()
, node()
, and xs:anyAtomicType
.
More complicated item types, especially those that are dependent on information in a schema,
are available using factory methods on the ItemTypeFactory
object.

item
- the item to be tested against this item typepublic boolean subsumes(ItemType other)
A.subsumes(B) is true if every value that matches the ItemType B also matches
the ItemType A.
