Method Details

makeVariant

public static ItemType.BuiltInAtomicItemType makeVariant(ItemType.BuiltInAtomicItemType type,
 ConversionRules conversionRules)

getConversionRules

public ConversionRules getConversionRules()

Description copied from class: ItemType

Get the conversion rules implemented by this type. The conversion rules reflect variations between different versions of the W3C specifications, for example XSD 1.1 allows "+INF" as a lexical representation of xs:double, while XSD 1.0 does not.

Overrides:

getConversionRules in class ItemType

Returns:

the conversion rules

matches

public boolean matches(XdmItem item)

Description copied from class: ItemType

Determine whether this item type matches a given item.

Specified by:

matches in class ItemType

Parameters:

item - the item to be tested against this item type

Returns:

true if the item matches this item type, false if it does not match.

subsumes

public boolean subsumes(ItemType other)

Description copied from class: ItemType

Determine whether this ItemType subsumes another ItemType. Specifically, A.subsumes(B) is true if every value that matches the ItemType B also matches the ItemType A.

Specified by:

subsumes in class ItemType

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.

getUnderlyingItemType

public ItemType getUnderlyingItemType()

Description copied from class: ItemType

Method to get the underlying Saxon implementation object

This gives access to Saxon methods that may change from one release to another.

Overrides:

getUnderlyingItemType in class ItemType

Returns:

the underlying Saxon implementation object

toString

public String toString()

Description copied from class: ItemType

Get a string representation of the type. This will be generally a string that conforms to the XPath ItemType production, for example a QName, or a construct such as "node()" or "map(*)".

QNames are generally in EQName (Q{uri}local) format, except that the prefix xs: is used for the XML Schema namespace.

If the type is an anonymous schema type, the name of the nearest named base type will be given, preceded by the character "<".

In the case of a function item type, the returned string will be in parentheses (for example (function() as xs:string)) so that an occurrence indicator can be added without ambiguity.

Overrides:

toString in class ItemType

Returns:

a string representation of the type
