Overview
This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.
Resolver for JSON path that uses the Puppet parser to create the AST. The path must start with ‘$’ which denotes the value that is passed into the parser. This parser can easily be extended with more elaborate resolution mechanisms involving document sets.
The parser is limited to constructs generated by the JsonPath#to_json_path method.
