## Detailed Description

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

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 , which enabled non-blocking I/O on the <SVC_HANDLER> when it is opened.

## Member Function Documentation

template<classSVC_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). Reimplemented from ACE_Connector.

template<classSVH, PR_CO_1>
int ACE_Strategy_Connector<SVH, >::close ( | void )`[virtual]`

| Close down the Connector. Reimplemented from ACE_Connector.

ACE_Connect_Strategy< SVC_HANDLER,ACE_PEER_CONNECTOR_2 >* ACE_Strategy_Connector< SVH,PR_CO_2 >::connect_strategy ( | void ) const`[virtual]`

template<classSVH, PR_CO_1>
int ACE_Strategy_Connector< SVH,PR_CO_2 >::connect_svc_handler ( | SVH *& sh,
| SVH *& sh_copy,
| const ACE_PEER_CONNECTOR_ADDR & remote_addr,
| ACE_Time_Value * timeout,
| const ACE_PEER_CONNECTOR_ADDR & local_addr,
| int reuse_addr,
| int flags,
| 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.

template<classSVH, PR_CO_1>
int ACE_Strategy_Connector< SVH,PR_CO_2 >::connect_svc_handler ( | SVH *& sh,

| ACE_Time_Value * timeout,
| const ACE_PEER_CONNECTOR_ADDR & local_addr,
| int reuse_addr,
| int flags,
| 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>.

ACE_Creation_Strategy< SVC_HANDLER >* ACE_Strategy_Connector< SVH,PR_CO_2 >::creation_strategy ( | void ) const`[virtual]`

template<classSVC_HANDLER, ACE_PEER_CONNECTOR_1>
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. Reimplemented from ACE_Connector.

| ACE_Connect_Strategy< SVC_HANDLER,ACE_PEER_CONNECTOR_2 >* = 0,
| ACE_Concurrency_Strategy< SVC_HANDLER >* = 0,
| int flags = 0 )`[virtual]`

| 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 , which enabled non-blocking I/O on the <SVC_HANDLER> when it is opened.

template<classSVH, PR_CO_1>
int ACE_Strategy_Connector<SVH, >::open ( | ACE_Reactor * r,
| int flags )`[virtual]`

| 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 , which enabled non-blocking I/O on the <SVC_HANDLER> when it is opened. Default strategies would be created and used. Reimplemented from ACE_Connector.
