Method Detail
-
getConversionRules
public ConversionRules getConversionRules()
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 classItemType
- Returns:
- the conversion rules
-
matches
public boolean matches(XdmItem item) throws SaxonApiUncheckedException
Determine whether this item type matches a given item.- Specified by:
matches
in classItemType
- 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.
- Throws:
SaxonApiUncheckedException
- in the rare event that the item is a map or array containing a lazily evaluated sequence, and evaluation of the sequence fails with a dynamic error in the course of checking
-
subsumes
public boolean subsumes(ItemType other)
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.
-
getUnderlyingItemType
public ItemType getUnderlyingItemType()
Method to get the underlying Saxon implementation objectThis gives access to Saxon methods that may change from one release to another.
- Specified by:
getUnderlyingItemType
in classItemType
- Returns:
- the underlying Saxon implementation object
-
getProcessor
protected Processor getProcessor()
Get the underlying Processor- Returns:
- the processor used to create this ItemType. This will be null if the ItemType is one of the three
static constant item types
ItemType.ANY_ITEM
,ItemType.ANY_NODE
, orItemType.ANY_ATOMIC_VALUE
