Method Detail

createQuery

public static QueryRootNode createQuery(String statement,
                                        NameResolver resolver,
                                        QueryNodeFactory factory)
                                 throws InvalidQueryException

Creates a QueryNode tree from a XPath statement using the passed query node factory.

Parameters:

statement - the XPath statement.

resolver - the name resolver to use.

factory - the query node factory.

Returns:

the QueryNode tree for the XPath statement.

Throws:

InvalidQueryException - if the XPath statement is malformed.

toString

public static String toString(QueryRootNode root,
                              NameResolver resolver)
                       throws InvalidQueryException

Creates a String representation of the query node tree in XPath syntax.

Parameters:

root - the root of the query node tree.

resolver - to resolve Names.

Returns:

a String representation of the query node tree.

Throws:

InvalidQueryException - if the query node tree cannot be converted into a String representation due to restrictions in XPath.

visit

public Object visit(SimpleNode node,
                    Object data)

Implements the generic visit method for this XPathVisitor.

Specified by:

visit in interface XPathVisitor

Parameters:

node - the current node as created by the XPath parser.

data - the current QueryNode created by this XPathVisitor.

Returns:

the current QueryNode. Can be different from data.
