Detailed Description

template<class SVC_HANDLER, ACE_PEER_CONNECTOR_1>
class ACE_Strategy_Connector< SVC_HANDLER, ACE_PEER_CONNECTOR_1 >

Abstract factory for creating a service handler (SVC_HANDLER), connecting the SVC_HANDLER, and activating the SVC_HANDLER.

Implements a flexible and extensible set of strategies for actively establishing connections with clients. There are three main strategies: (1) creating a SVC_HANDLER, (2) actively initiating a new connection from the client, and (3) activating the SVC_HANDLER with a particular concurrency mechanism after the connection is established.

Initialize a connector. flags indicates how SVC_HANDLER's should be initialized prior to being activated. Right now, the only flag that is processed is ACE_NONBLOCK, which enabled non-blocking I/O on the SVC_HANDLER when it is opened.

template<class SVC_HANDLER , ACE_PEER_CONNECTOR_1 >
int ACE_Strategy_Connector< SVC_HANDLER, ACE_PEER_CONNECTOR_1 >::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).

Bridge method for connecting the new connection into the SVC_HANDLER. The default behavior delegates to the <PEER_CONNECTOR::connect> in the <Connect_Strategy>.

)
protectedvirtual

Bridge method for connecting the new connection into the SVC_HANDLER. The default behavior delegates to the <PEER_CONNECTOR::connect> in the <Connect_Strategy>. sh_copy is used to obtain a copy of the sh pointer, but that can be kept in the stack; the motivation is a bit too long to include here, but basically we want to modify sh safely, using the internal locks in the Connect_Strategy, while saving a TSS copy in sh_copy, usually located in the stack.

int ACE_Strategy_Connector< SVC_HANDLER, ACE_PEER_CONNECTOR_1 >::make_svc_handler ( SVC_HANDLER *&  sh)
protectedvirtual

Bridge method for creating a SVC_HANDLER. The strategy for creating a SVC_HANDLER are configured into the Connector via it's <creation_strategy_>. 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.
