get_callback()

template<typename DataType>

std::shared_ptr< std::function< void(DataType &&)> > dunedaq::datahandlinglibs::DataMoveCallbackRegistry::get_callback ( const appmodel::DataMoveCallbackConf * conf )

inline

Gets the callback function registered with the given configuration.

Template Parameters

DataType

The expected parameter type of the callback function

Parameters

conf	The configuration object containing the unique identifier for the callback

Returns

A shared pointer to the callback function

Exceptions

GenericConfigurationError

if the registered callback function's parameter type does not match DataType
