attribute()

template<typename T>

T dbe::config::api::graph::linked::through::attribute	(	tref	item,
		dunedaq::conffwk::attribute_t const &	attr )

Get object reference/s through a specified attribute

e.g. A-C->B

returns B for object A through relation C

Parameters

item	is the object to retrieve the relation value
relation	is the relation to retrieve the value for

Returns

the value of the relation converted to the specified type

attributes()

template<typename T>

template std::vector< tref > dbe::config::api::graph::linked::through::attributes< tref >

(

tref const &

item

)

Get objects referenced by an object through any attributes

e.g. A-c->B , and another A-c->D returns {B,D} but A-c->B , A-d->B return {B}

Parameters

item	is the object for which objects must be retrieved

Returns

a vector of linked objects

relation()

template<typename T>

T dbe::config::api::graph::linked::through::relation	(	tref	item,
