string Input::PathBase::as_string ( ) const

Returns string address of current position.

Definition at line 48 of file path_base.cc.

Here is the caller graph for this function:

virtual PathBase* Input::PathBase::clone ( ) const
pure virtual

Create copy of derived class.

Implemented in Input::PathYAML, and Input::PathJSON.

Here is the caller graph for this function:

Input::PathBase::DECLARE_INPUT_EXCEPTION ( ExcRefOfWrongType  ,
<< "Reference at address "<< EI_ErrorAddress::qval<< " has wrong  type,
should by string."

)
virtual bool Input::PathBase::down ( unsigned int  index)
pure virtual

Dive one level down into path hierarchy.

Store current path and returns true if pointer to new node is not NULL.

Implemented in Input::PathYAML, and Input::PathJSON.

Here is the caller graph for this function:

virtual bool Input::PathBase::down ( const std::string &  key,
int  index = -1 
)
pure virtual

Dive one level down into path hierarchy.

Store current path and returns true if pointer to new node is not NULL.

Implemented in Input::PathYAML, and Input::PathJSON.

virtual PathBase* Input::PathBase::find_ref_node ( )
pure virtual

Check if current head node is containing one key REF of type string.

If yes, creates a new path object given by address string possibly relative to the current path. In other else return NULL.

This method has the meaning only for JSON. For YAML (YAML has native references) return always NULL.

Implemented in Input::PathJSON, and Input::PathYAML.

Here is the caller graph for this function:

virtual int Input::PathBase::get_array_size ( ) const
pure virtual

Get size of array (sequence type), if object is not array return -1.

Implemented in Input::PathYAML, and Input::PathJSON.

Here is the caller graph for this function:

virtual bool Input::PathBase::get_bool_value ( ) const
pure virtual

Get boolean value of head node or throw exception.

Implemented in Input::PathYAML, and Input::PathJSON.

Here is the caller graph for this function:

virtual double Input::PathBase::get_double_value ( ) const
pure virtual

Get double value of head node or throw exception.

Implemented in Input::PathYAML, and Input::PathJSON.

Here is the caller graph for this function:

virtual std::int64_t Input::PathBase::get_int_value ( ) const
pure virtual

Get integer value of head node or throw exception.

Implemented in Input::PathYAML, and Input::PathJSON.

Here is the caller graph for this function:

std::string Input::PathBase::get_node_type ( unsigned int  type_idx) const

Get short string description of node type, method is used for printout of messages.

Definition at line 64 of file path_base.cc.

Here is the caller graph for this function:

virtual unsigned int Input::PathBase::get_node_type_index ( ) const
pure virtual

Get index of head type, value corresponds with order in json_type_names vector.

Implemented in Input::PathYAML, and Input::PathJSON.

Here is the caller graph for this function:

virtual bool Input::PathBase::get_record_key_set ( std::set< std::string > &  ) const
pure virtual

Get set of keys of head type record, if head type is not record return false.

Implemented in Input::PathYAML, and Input::PathJSON.

Here is the caller graph for this function:

virtual std::string Input::PathBase::get_record_tag ( ) const
pure virtual

Gets value of the record tag, which determines its type.

  • for JSON gets value of TYPE key
  • for YAML gets value of tag

Typically is used for getting descendant or for include of other input file.

Implemented in Input::PathYAML, and Input::PathJSON.

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 175 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.
