template<typename SVC_HANDLER, typename PEER_CONNECTOR>
class ACE_Connector< SVC_HANDLER, PEER_CONNECTOR >
Generic factory for actively connecting clients and creating service handlers (SVC_HANDLERs).
Implements the strategy for actively establishing connections with clients. Both blocking and non-blocking connects are supported. Moreover, non-blocking connects support timeouts.
An ACE_Connector is parameterized by concrete types that conform to the interfaces of SVC_HANDLER and PEER_CONNECTOR described below.
- Template Parameters
-
SVC_HANDLER | The name of the concrete type that performs the application-specific service. The SVC_HANDLER typically inherits from ACE_Svc_Handler. |
- See Also
- Svc_Handler.h.
- Template Parameters
-
PEER_CONNECTOR | The name of the class that implements the PEER_CONNECTOR endpoint (e.g., ACE_SOCK_Connector) to passively establish connections. A PEER_CONNECTOR implementation must provide a PEER_STREAM and PEER_ADDR trait to identify the type of stream (e.g., ACE_SOCK_Stream) and type of address (e.g., ACE_INET_Addr) used by the endpoint. |
template<typename SVC_HANDLER , typename PEER_CONNECTOR >
int ACE_Connector< SVC_HANDLER, PEER_CONNECTOR >::activate_svc_handler |
( |
SVC_HANDLER * |
svc_handler | ) |
|
|
protectedvirtual |
Bridge method for activating a svc_handler with the appropriate concurrency strategy. The default behavior of this method is to activate the SVC_HANDLER by calling its <open> method (which allows the SVC_HANDLER to define its own concurrency strategy). However, subclasses can override this strategy to do more sophisticated concurrency activations (such as creating the SVC_HANDLER as an "active object" via multi-threading or multi-processing).
Reimplemented in ACE_Strategy_Connector< SVC_HANDLER, PEER_CONNECTOR >.
template<typename SVC_HANDLER , typename PEER_CONNECTOR >
int ACE_Connector< SVC_HANDLER, PEER_CONNECTOR >::make_svc_handler |
( |
SVC_HANDLER *& |
sh | ) |
|
|
protectedvirtual |
Bridge method for creating a SVC_HANDLER. The default is to create a new SVC_HANDLER only if sh == 0, else sh is unchanged. However, subclasses can override this policy to perform SVC_HANDLER creation in any way that they like (such as creating subclass instances of SVC_HANDLER, using a singleton, dynamically linking the handler, etc.). Returns -1 if failure, else 0.
Reimplemented in ACE_Strategy_Connector< SVC_HANDLER, PEER_CONNECTOR >.
