inline void add_key_t(FitsKeys &keydb, const std::string &keyword, const T &value, const std::string &comment, std::string type_override)#

template class adds key,value,comment to indicated keydb

Parameters:

  • keydb – [in] reference to FitsKeys database map

  • keyword – [in] name of header keyword

  • value – [in] value of template type <T>

  • comment – [in] comment string for header keyword

template<typename T>
inline void add_key(const std::string &keyword, const T &value, const std::string &comment, bool use_extension, const std::string &chan = "")#
inline void add_json_key(const json &jmessage, const std::string &jkey, const std::string &keyword, const std::string &comment, const std::string &type, bool use_extension, const std::string &chan = "")#

template class adds key,value,comment to indicated keydb from json message

This extracts the value from a JSON message and uses add_key to add the keyword to the indicated database map.

Parameters:

  • jmessage – [in] JSON message is the source of the value

  • jkey – [in] key to index jmessage

  • keyword – [in] FITS header keyword

  • comment – [in] comment string for header keyword

  • type – [in] type of key can be optionally specified

  • use_extension – [in] extension or primary

  • chan – [in] channel selects keyword db
