Member Data Documentation

config_value(* caf::config_option::meta_state::get) (const void *)

Tries to extract a value from the given location.

Exists for backward compatibility only and will get removed with CAF 0.17.

error(* caf::config_option::meta_state::sync) (void *, config_value &)

Tries to perform this sequence of steps:

Convert the config value to the type of the config option.
Assign the converted value back to the config value to synchronize conversions back to the caller.
Store the converted value in the pointer unless it is nullptr.
