Detailed Description

struct specifying actual link data between observers and subjects

Remarks

Used internally by SignalHub. There is no copy constructor and copy assignment, a LinkUnit is meant to be created only once for each connection.

default destructor

Member Function Documentation

template<typename Function >

Function& utility::signals::LinkUnit::fref ( )

inline

return a reference to the function object with requested cast

References fn.
