Detailed Description

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

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, >::activate_svc_handler SVC_HANDLER *  svc_handler  )  [protected, virtual]
 

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).

int  reuse_addr,

int  perms
[protected, virtual]
 

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, >::make_svc_handler SVC_HANDLER *&  sh  )  [protected, virtual]
 

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.
