Some transports need to be able to identify clients.
For example, a fanout transport must, when there's no
data remaining, send an end to all remaining
clients. The CClientRegistry
allows each client to have a unique uint64_t
identifier.
It provides the facility to add and remove clients, to test for the presence of clients and to test for an empty client registry.
The class prevents client duplication and
removal of nonexistent clients by throwing
std::logic_error
exceptions.
void add(uint64_t newId);
Adds newId to the set of
identifiers that are registered. If
newId has already
been registered,
std::logic_error is
thrown.
void remove(uint64_t existingId);
Removes the id
existingId from the
registry. If that id was not yet registered,
a std::logic_error
is thrown.
bool hasClient(uint64_t id);
Returns true if
id is in the registry
otherwise false is returned.
bool empty();
Return true if the registry has no entryies.
