ACE_SOCK_SEQPACK_Association
object.
The ACE_SOCK_SEQPACK_Connector
doesn't have a socket of its own, i.e., it simply "borrows" the one from the ACE_SOCK_SEQPACK_Association
that's being connected. The reason for this is that the underlying socket API doesn't use a factory socket to connect data mode sockets. Therefore, there's no need to inherit ACE_SOCK_SEQPACK_Connector
from ACE_SOCK
. A nice side-effect of this is that ACE_SOCK_SEQPACK_Connector
objects do not store state so they can be used reentrantly in multithreaded programs.
