EPS::TConnPtr EPS::Tracker::get_shared_pointer ( EPS::TCPConnection * connection )

Look through all the shared pointers that Tracker knows about and see if we can find one matching the given raw pointer.

If one doesn't exist, then throw an exception.

Here is the call graph for this function:

Here is the caller graph for this function:

◆ import_from_cache()

void EPS::Tracker::import_from_cache ( const IPv4 & network )

Import the tracker information (if any).

See also: EPS::Tracker::export_to_cache()
