Class NamespaceTest
- ItemType, Serializable
public final class NamespaceTest
NodeTest is an interface that enables a test of whether a node has a particular
name and type. A NamespaceTest matches the node type and the namespace URI.
boolean | equals(Object other) - Indicates whether some other object is "equal to" this one.
|
double | getDefaultPriority() - Determine the default priority of this node test when used on its own as a Pattern
|
String | getNamespaceURI() - Get the namespace URI matched by this NamespaceTest
|
int | getNodeKindMask() - Get a mask indicating which kinds of nodes this NodeTest can match.
|
int | getPrimitiveType() - Determine the types of nodes to which this pattern applies.
|
ItemType | getSuperType(TypeHierarchy th) - Get the type from which this item type is derived by restriction.
|
int | hashCode() - Returns a hash code value for the object.
|
boolean | matches(int nodeType, int fingerprint, int annotation) - Test whether this node test is satisfied by a given node
|
boolean | matches(NodeInfo node) - Test whether this node test is satisfied by a given node.
|
boolean | matches(TinyTree tree, int nodeNr) - Test whether this node test is satisfied by a given node on a TinyTree.

NamespaceTest
public NamespaceTest(NamePool pool,
int nodeKind,
String uri)
equals
public boolean equals(Object other)
Indicates whether some other object is "equal to" this one.
getDefaultPriority
public final double getDefaultPriority()
Determine the default priority of this node test when used on its own as a Pattern
- getDefaultPriority in interface NodeTest
getNamespaceURI
public String getNamespaceURI()
Get the namespace URI matched by this NamespaceTest
- the namespace URI matched by this NamespaceTest
getNodeKindMask
public int getNodeKindMask()
Get a mask indicating which kinds of nodes this NodeTest can match. This is a combination
of bits: 1<<Type.ELEMENT for element nodes, 1<<Type.TEXT for text nodes, and so on.
- getNodeKindMask in interface NodeTest
getPrimitiveType
public int getPrimitiveType()
Determine the types of nodes to which this pattern applies. Used for optimisation.
For patterns that match nodes of several types, return Type.NODE
- getPrimitiveType in interface ItemType
- getPrimitiveType in interface NodeTest
- the type of node matched by this pattern. e.g. Type.ELEMENT or Type.TEXT
getSuperType
public ItemType getSuperType(TypeHierarchy th)
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 xs: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.
- getSuperType in interface ItemType
- getSuperType in interface NodeTest
th
- the type hierarchy cache
- the supertype, or null if this type is item()
hashCode
public int hashCode()
Returns a hash code value for the object.
matches
public boolean matches(int nodeType,
int fingerprint,
int annotation)
Test whether this node test is satisfied by a given node
- matches in interface NodeTest
nodeType
- The type of node to be matchedfingerprint
- identifies the expanded name of the node to be matched
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.
- matches in interface NodeTest
node
- the node to be matched
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 in interface NodeTest
tree
- the TinyTree containing the nodenodeNr
- the number of the node within the TinyTree
