Method Detail
-
getInstance
public static AnyNodeTest getInstance()
Get an instance of AnyNodeTest
-
matchesItem
public boolean matchesItem(Item item, boolean allowURIPromotion, Configuration config)
Test whether a given item conforms to this type- Specified by:
matchesItem
in interfaceItemType
- Overrides:
matchesItem
in classNodeTest
- Parameters:
item
- The item to be testedallowURIPromotion
-config
-- Returns:
- true if the item is an instance of this type; false otherwise
-
getSuperType
public ItemType getSuperType(TypeHierarchy th)
Description copied from class:NodeTest
Get the type from which this item type is derived by restriction. This is the supertype in the XPath type heirarchy, as distinct from the Schema base type: this means that the supertype of xs:boolean is xdt:anyAtomicType, whose supertype is item() (rather than xs:anySimpleType).In fact the concept of "supertype" is not really well-defined, because the types form a lattice rather than a hierarchy. The only real requirement on this function is that it returns a type that strictly subsumes this type, ideally as narrowly as possible.
- Specified by:
getSuperType
in interfaceItemType
- Overrides:
getSuperType
in classNodeTest
- Returns:
- the supertype, or null if this type is item()
-
matches
public final boolean matches(int nodeType, int fingerprint, int annotation)
Test whether this node test is satisfied by a given node
-
matches
public boolean matches(TinyTree tree, int nodeNr)
Test whether this node test is satisfied by a given node on a TinyTree. The node must be a document, element, text, comment, or processing instruction node. This method is provided so that when navigating a TinyTree a node can be rejected without actually instantiating a NodeInfo object.
-
matches
public boolean matches(NodeInfo node)
Test whether this node test is satisfied by a given node. This alternative method is used in the case of nodes where calculating the fingerprint is expensive, for example DOM or JDOM nodes.
-
getDefaultPriority
public final double getDefaultPriority()
Determine the default priority of this node test when used on its own as a Pattern- Specified by:
getDefaultPriority
in classNodeTest
-
getNodeKindMask
public int getNodeKindMask()
Get a mask indicating which kinds of nodes this NodeTest can match. This is a combination of bits: 1<- Specified by:

toString
public java.lang.String toString()
- Overrides:
toString
in classjava.lang.Object
-
hashCode
public int hashCode()
Returns a hash code value for the object.- Overrides:
