Detailed Description

Class used by ReaderToStorage class to iterate over the JSON tree provided by json_spirit library.

This class keeps whole path from the root of the JSON tree to the current node. We store nodes along path in nodes_ and address of the node in path_.

The class also contains methods for processing of special keys 'REF' and 'TYPE'. The reference is record with only one key 'REF' with a string value that contains address of the reference. The string with the address is extracted and provided by method JSONtoStorage::find_ref_node.
