supported.

otherwise.
evaluate
public List<Node> evaluate(Node node,
RuleContext data)
- Evaluate the XPath query against the given Node.
- Specified by:
evaluate
in interface XPathRuleQuery
- Specified by:
evaluate
in class AbstractXPathRuleQuery
- Parameters:
node
- The Node.data
- The RuleContext.
- Returns:
- The matching Nodes.
getRuleChainVisits
public List<String> getRuleChainVisits()
- Indicates which AST Nodes (if any) should be used with the RuleChain.
Use of the RuleChain will allow the query execute on a targed sub-tree
of the AST, instead of the entire AST from the root. This can result
in great performance benefits.
- Specified by:
getRuleChainVisits
in interface XPathRuleQuery
- Overrides:
