java.lang.Object net.sf.saxon.s9api.ItemType
public abstract class ItemType
An item type, as defined in the XPath/XQuery specifications.
This class contains a number of static constant fields
referring to instances that represent simple item types, such as
item()
, node()
, and xs:anyAtomicType
. These named types are currently
based on the definitions in XSD 1.0 and XML 1.0. They may be changed in a future version to be based
on a later version.
More complicated item types, especially those that are dependent on information in a schema,
are available using factory methods on the ItemTypeFactory
object. The factory methods can
also be used to create variants of the types that use the rules given in the XML 1.1 and/or XSD 1.1 specifications.

public abstract ConversionRules getConversionRules()
public abstract boolean matches(XdmItem item)
item
- the item to be tested against this item type
public abstract boolean subsumes(ItemType other)
A.subsumes(B) is true if every value that matches the ItemType B also matches
the ItemType A.
- Parameters:
other
- the other ItemType
- Returns:
- true if this ItemType subsumes the other ItemType. This includes the case where A and B
represent the same ItemType.
- Since:
- 9.1
public abstract ItemType getUnderlyingItemType()
This gives access to Saxon methods that may change from one release to another.
