Class AnyChildNodeTest

java.lang.Object
  extended by net.sf.saxon.pattern.NodeTest
      extended by net.sf.saxon.pattern.AnyChildNodeTest
All Implemented Interfaces:
Serializable, ItemType

public final class AnyChildNodeTest
extends NodeTest

An AnyChildNodePattern is the pattern node(), which matches any node except a root node, an attribute node, or a namespace node: in other words, any node that is the child of another node.

Method Detail

getInstance

public static AnyChildNodeTest getInstance()
Get the singular instance of this class

Returns:
the singular instance

matches

public boolean matches(int nodeKind,
                       NodeName name,
                       int annotation)
Test whether this node test is satisfied by a given node. This method is only fully supported for a subset of NodeTests, because it doesn't provide all the information needed to evaluate all node tests. In particular (a) it can't be used to evaluate a node test of the form element(N,T) or schema-element(E) where it is necessary to know whether the node is nilled, and (b) it can't be used to evaluate a node test of the form document-node(element(X)). This in practice means that it is used (a) to evaluate the simple node tests found in the XPath 1.0 subset used in XML Schema, and (b) to evaluate node tests where the node kind is known to be an attribute.

Specified by:
matches in class NodeTest
Parameters:
nodeKind - The kind of node to be matched
name - identifies the expanded name of the node to be matched. The value should be null for a node with no name.
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

getDefaultPriority

public double getDefaultPriority()
Determine the default priority to use if this pattern appears as a match pattern for a template with no explicit priority attribute.

Returns:
the default priority

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
Returns:
a combination of bits: 1<

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
