template<typename T >

template QStringList dbe::config::api::get::attribute::list< QStringList > ( dbe::inner::configobject::tref obj, dunedaq::conffwk::attribute_t const & attr )

inlinestatic

Retrieve a list from of an unspecified type of the values of the attribute of an object

Parameters

obj	is the reference of the object to operate upon
attr	is the Attribute type information structure

Returns

a list of type T with the attribute values
