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
