             *     If \p approach == PreFix, then \p pattern looks like "name_". And a node named "name_abc" would match.
             *     If \p approach == PostFix, then \p pattern looks like "_name". And a node named "abc_name" would match.
             *     If \p approach == RegEx, the \p pattern is a regular expression.
             * @approach: See \p pattern.
             * @virtualType: This string will be internally CRC32'ed. For nodes that match \p pattern, this will be
             *     the virtual type of the node.
             * @includeChildren: For each parent node, If true, it will do pattern matching across the children nodes,
             *     otherwise the pattern matching will always stop at root nodes. 
             * @returns: true if the new \p virtualType doesn't exist already (matched by Crc) AND
             *     it is added to the end of the list.
