matches
public boolean matches(Node node)
- Description copied from interface:
Pattern
- DOCUMENT ME!
- Parameters:
node
- DOCUMENT ME!- Returns:
- true if the pattern matches the given DOM4J node.
getText
public String getText()
getPriority
public double getPriority()
- Description copied from interface:
Pattern
- Returns the default resolution policy of the pattern according to the XSLT conflict resolution
spec .
- Specified by:
getPriority
in interfacePattern
- Returns:
- DOCUMENT ME!
getUnionPatterns
public Pattern[] getUnionPatterns()
- Description copied from interface:
Pattern
- If this pattern is a union pattern then this method should return an
array of patterns which describe the union pattern, which should contain
more than one pattern. Otherwise this method should return null.
- Specified by:
getUnionPatterns
in interfacePattern
- Returns:
- an array of the patterns which make up this union pattern or null if this pattern is not a union pattern
getMatchType
public short getMatchType()
- Description copied from interface:
Pattern
- DOCUMENT ME!
- Specified by:
getMatchType
in interfacePattern
- Returns:
- the type of node the pattern matches which by default should return ANY_NODE if it can match any kind of node.
getMatchesNodeName
public String getMatchesNodeName()
- Description copied from interface:
Pattern
- For patterns which only match an ATTRIBUTE_NODE or an ELEMENT_NODE then
this pattern may return the name of the element or attribute it matches.
This allows a more efficient rule matching algorithm to be performed,
rather than a brute force approach of evaluating every pattern for a
given Node.
- Specified by:
getMatchesNodeName
in interfacePattern
- Returns:
- the name of the element or attribute this pattern matches or null if this pattern matches any or more than one name.
setVariableContext
public void setVariableContext(org.jaxen.VariableContext variableContext)
toString
public String toString()
getContextSupport
protected org.jaxen.ContextSupport getContextSupport()
handleJaxenException
protected void handleJaxenException(org.jaxen.JaxenException exception) throws XPathException
- Throws:
XPathException
