definition()

dunedaq::conffwk::class_t dbe::config::api::info::onclass::definition ( std::string const & cn, bool direct_only )

static

Get class information from class name

Parameters

cn	is the class name to retrieve information for
determines	if class information should include direct-only relation, attribute , sub-class and superclass information

Returns

a class information object

derived()

bool dbe::config::api::info::onclass::derived ( std::string const & fromclass, std::string const & aclass )

static

Determine if a class is derived from another

Parameters

fromclass	is the classname of the class the we want to see if a class is derived from
aclass	is the classname of the candidate class to be derived from inclass

Returns

true if aclass is derived fromclass
