Method Detail

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.
-
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
public boolean matches(NodeInfo node)
Determine whether this Pattern matches the given Node.
-
getDefaultPriority
public final double getDefaultPriority()
Determine the default priority of this node test when used on its own as a Pattern- Returns:
- the default priority
-
getPrimitiveType
public int getPrimitiveType()
Determine the types of nodes to which this pattern applies. Used for optimisation.- Specified by:
getPrimitiveType
in interfaceItemType
- Overrides:
getPrimitiveType
in classNodeTest
- 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 classNodeTest
- Returns:
- a combination of bits: 1<
-
getElementTest
public NodeTest getElementTest()
Get the element test contained within this document test- Returns:
- the contained element test
-
