Detailed Description

Class used by JSONToStorage 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 by JSONToStorage::get_ref_from_head then the JSONPath corresponding to the address is provided by method JSONtoStorage::find_ref_node.

const JSONPath::Node * Input::JSONPath::down ( unsigned int index )

Dive into json_spirit hierarchy. Store current path and returns pointer to new json_spirit node. If the json_spirit type do not match returns NULL.

JSONPath Input::JSONPath::find_ref_node ( const string & ref_address )

Creates a new JSONPath object given by address string possibly relative to the current path.

This returns path to reference given by address in ref_address.

Here is the caller graph for this function:

bool Input::JSONPath::get_ref_from_head ( string & ref_address )

Check if current head node is a JSON Object containing one key REF of type string. If yes, returns the string through reference ref_address.

vector< pair<int, string> > Input::JSONPath::path_

private

One level of the path_ is either index (nonnegative int) in array or string key in a json object. For the first type we save index into first part of the pair and empty string to the second. For the later type of level, we save -1 for index and the key into the secodn part of the pair.
