Definition at line 14 of file YAMLReader.h.

Public Types

using node_finder_t = std::function<YAML::Node(YAML::Node const)>
 A function f : Node A -> Node B which searches YAML::Node A for a specific YAML::Node B, returning it.
using node_id_t = std::variant<std::string, node_finder_t>
using node_path_t = std::deque<node_id_t>
 Representation of a path of YAML::Nodes in a YAML::Node tree, e.g., in a YAML file.

Member Typedef Documentation

◆ node_finder_t

using iguana::YAMLReader::node_finder_t = std::function<YAML::Node(YAML::Node const)>

A function f : Node A -> Node B which searches YAML::Node A for a specific YAML::Node B, returning it.

Definition at line 20 of file YAMLReader.h.

◆ node_id_t

using iguana::YAMLReader::node_id_t = std::variant<std::string, node_finder_t>

Variant for identifying a YAML::Node:

  • std::string: the key name of the node
  • node_finder_t: how to find the node

Definition at line 25 of file YAMLReader.h.

◆ node_path_t

using iguana::YAMLReader::node_path_t = std::deque<node_id_t>

Representation of a path of YAML::Nodes in a YAML::Node tree, e.g., in a YAML file.

Definition at line 28 of file YAMLReader.h.

Member Function Documentation

◆ GetScalar() [1/2]

template<typename SCALAR>
std::optional< SCALAR > iguana::YAMLReader::GetScalar ( node_path_t node_path)

Read a scalar value from a YAML::Node path; searches all currently loaded config files.

Parameters
node_paththe YAML::Node path
Returns
the scalar, if found

◆ GetScalar() [2/2]

template<typename SCALAR>
std::optional< SCALAR > iguana::YAMLReader::GetScalar ( YAML::Node node)

Read a scalar value from a YAML::Node

Parameters
nodethe YAML::Node to read
Returns
the scalar, if found

◆ GetVector() [1/2]

template<typename SCALAR>
std::optional< std::vector< SCALAR > > iguana::YAMLReader::GetVector ( node_path_t node_path)

Read a vector value from a YAML::Node path; searches all currently loaded config files.

Parameters
node_paththe YAML::Node path
Returns
the vector, if found

◆ GetVector() [2/2]

template<typename SCALAR>
std::optional< std::vector< SCALAR > > iguana::YAMLReader::GetVector ( YAML::Node node)

Read a vector value from a YAML::Node

Parameters
nodethe YAML::Node to read
Returns
the vector, if found

◆ InRange()

template<typename SCALAR>
node_finder_t iguana::YAMLReader::InRange ( std::string const & key,
SCALAR val )

Create a function to search a YAML::Node for a sub-YAML::Node such that the scalar val is within a range specified by key

Parameters
keythe key of the sub-YAML::Node to use as the range (its value must be a 2-vector)
valthe scalar value to check
Returns
the search function
