template<typename SVC_HANDLER, typename PEER_ACCEPTOR>
class ACE_Strategy_Acceptor< SVC_HANDLER, PEER_ACCEPTOR >
Abstract factory for creating a service handler (SVC_HANDLER), accepting into the SVC_HANDLER, and activating the SVC_HANDLER.
Implements a flexible and extensible set of strategies for passively establishing connections with clients. There are three main strategies: (1) creating a SVC_HANDLER, (2) passively accepting a new connection from a client into the SVC_HANDLER, and (3) activating the SVC_HANDLER with a particular concurrency mechanism.

|
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 from ACE_Acceptor< SVC_HANDLER, PEER_ACCEPTOR >.
template<typename SVC_HANDLER , typename PEER_ACCEPTOR >
Bridge method for creating a {SVC_HANDLER}. The strategy for creating a {SVC_HANDLER} are configured into the Acceptor via it's {creation_strategy_}. The default is to create a new {SVC_HANDLER} 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 on failure, else 0.

Open the contained PEER_ACCEPTOR object to begin listening, and register with the specified reactor for accept events.
The PEER_ACCEPTOR handle is put into non-blocking mode as a safeguard against the race condition that can otherwise occur between the time when the passive-mode socket handle is "ready" and when the actual accept call is made. During this interval, the client can shutdown the connection, in which case, the {accept} call can hang.
- Parameters
-
| local_addr | The address to listen at. |
| reactor | Pointer to the ACE_Reactor instance to register this object with. The default is the singleton. |
| flags | Flags to control what mode an accepted socket will be put into after it is accepted. The only legal value for this argument is ACE_NONBLOCK, which enables non-blocking mode on the accepted peer stream object in SVC_HANDLER. The default is 0. |
| use_select | Affects behavior when called back by the reactor when a connection can be accepted. If non-zero, this object will accept all pending connections, instead of just the one that triggered the reactor callback. Uses ACE_OS::select() internally to detect any remaining acceptable connections. The default is 1. |
| reuse_addr | Passed to the PEER_ACCEPTOR::open() method with local_addr. Generally used to request that the OS allow reuse of the listen port. The default is 1. |
- Return values
-
| 0 | Success |
| -1 | Failure, errno contains an error code. |
