Class LocalNameTest

java.lang.Object
  net.sf.saxon.pattern.NodeTest
      net.sf.saxon.pattern.LocalNameTest

All Implemented Interfaces:

Serializable, QNameTest, ItemType

public final class LocalNameTest
extends NodeTest
implements QNameTest

NodeTest is an interface that enables a test of whether a node has a particular name and type. A LocalNameTest matches the node type and the local name, it represents an XPath 2.0 test of the form *:name.

Constructor Detail

LocalNameTest

public LocalNameTest(NamePool pool,
                     int nodeKind,
                     String localName)

Method Detail

matches

public 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

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.

Overrides:

matches in class NodeTest

Parameters:

tree - the TinyTree containing the node

nodeNr - the number of the node within the TinyTree

Returns:

true if the node matches the NodeTest, otherwise false

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.

Overrides:

matches in class NodeTest

Parameters:

node - the node to be matched

matches

public boolean matches(StructuredQName qname)

Test whether this QNameTest matches a given QName

Specified by:

matches in interface QNameTest

Parameters:

qname - the QName to be matched

Returns:

true if the name matches, false if not

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 class NodeTest

getLocalName

public String getLocalName()

Get the local name used in this LocalNameTest

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

Specified by:

getPrimitiveType in interface ItemType

Overrides:

getPrimitiveType in class NodeTest

Returns:

the type of node matched by this pattern. e.g. Type.ELEMENT or Type.TEXT

getNodeKindMask

public int getNodeKindMask()

Get a mask indicating which kinds of nodes this NodeTest can match. This is a combination of bits: 1<

Overrides:

getNodeKindMask in class NodeTest

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Returns a hash code value for the object.

Overrides:

hashCode in class Object

equals

public boolean equals(Object other)

Indicates whether some other object is "equal to" this one.

Overrides:

equals in class Object
