Member Data Documentation

std::vector<std::string> Input::PathBase::json_type_names

protected

Names of all possible node types in parsed input tree.

Names are provided by JSON Spirit or YAML-cpp library. Initialized in constructor.

Definition at line 173 of file path_base.hh.

std::vector< std::pair<int, std::string> > Input::PathBase::path_

protected

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.
