SUBROUTINES "check_angle" check_angle($self, $key); *Since version 0.20.* Check parameter defined by $key which is number between 0 and 360. Put error if check isn't ok. Returns undef. "check_array" check_array($self, $key); *Since version 0.06.* Check parameter defined by $key which is reference to array. Put error if check isn't ok. Returns undef. "check_array_object" check_array_object($self, $key, $class, $class_name); *Since version 0.02. Described functionality since version 0.21.* Check parameter defined by $key which is reference to array with instances of some object type ($class). $class_name is used to error message. Put error if check isn't ok. Returns undef. "check_array_required" check_array_required($self, $key); *Since version 0.18. Described functionality since version 0.19.* Check parameter defined by $key which is reference to array for at least one value inside. Put error if check isn't ok. Returns undef.
