AnyNodeTest

public AnyNodeTest()
Method Detail

getInstance

public static AnyNodeTest getInstance()
Get an instance of AnyNodeTest


matchesItem

public boolean matchesItem(Item item)
Test whether a given item conforms to this type

Specified by:
matchesItem in interface ItemType
Overrides:
matchesItem in class NodeTest
Parameters:
item - The item to be tested
Returns:
true if the item is an instance of this type; false otherwise

getSuperType

public ItemType getSuperType()
Description copied from interface: ItemType
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).

Specified by:
getSuperType in interface ItemType
Overrides:
getSuperType in class NodeTest
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

Specified by:
matches in class NodeTest
Parameters:
nodeType - The type of node to be matched
fingerprint - identifies the expanded name of the node to be matched
annotation - The actual content type of the node

getDefaultPriority

public final double getDefaultPriority()
Determine the default priority of this node test when used on its own as a Pattern

Overrides:
getDefaultPriority in class Pattern

allowsTextNodes

public boolean allowsTextNodes()
Indicate whether this NodeTest is capable of matching text nodes

Specified by:
allowsTextNodes in class NodeTest

toString

public String toString()
Description copied from class: Pattern
Get the original pattern text

Specified by:
toString in interface ItemType
Overrides:
toString in class Pattern
