Implements the strategy for actively establishing connections with clients. An ACE_Connector is parameterized by concrete types that conform to the interfaces of PEER_CONNECTOR and SVC_HANDLER. The PEER_CONNECTOR is instantiated with a transport mechanism that actively establishes connections. The SVC_HANDLER is instantiated with a concrete type that performs the application-specific service. Both blocking and non-blocking connects are supported. Further, non-blocking connects support timeouts.

Initialize a connector. flags indicates how '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 when it is opened. |
|
||||||||||
|
Shutdown a connector and release resources.

|
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 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, >. |
|
||||||||||
|
Cancel the svc_handler that was started asynchronously. Note that this is the only case when the Connector does not actively close the svc_handler. It is left up to the caller of to decide the fate of the svc_handler. Referenced by ACE_Connector< SVC_HANDLER, ACE_PEER_CONNECTOR_2 >::close(). |
|
||||||||||
|
Close down the Connector. All pending non-blocking connects are canceled and the corresponding svc_handler is closed. Reimplemented in ACE_Strategy_Connector< SVC_HANDLER, >. Referenced by ACE_Connector< SVC_HANDLER, ACE_PEER_CONNECTOR_2 >::fini(), and ACE_Connector< SVC_HANDLER, ACE_PEER_CONNECTOR_2 >::~ACE_Connector(). |

|
This is a variation on the previous method. On cached connectors the svc_handler_hint variable can be used as a hint for future lookups. Since this variable is modified in the context of the internal cache its use is thread-safe. But the actual svc_handler for the current connection is returned in the second parameter svc_handler. If the connection fails the hook on the will be called automatically to prevent resource leaks. |
|
||||||||||||||||||||||||||||||||||||
|
Initiate connection of svc_handler to peer at remote_addr using synch_options. If the caller wants to designate the selected local_addr they can (and can also insist that the local_addr be reused by passing a value reuse_addr == 1). flags and perms can be used to pass any flags that are needed to perform specific operations such as opening a file within connect with certain permissions. If the connection fails the hook on the will be called automatically to prevent resource leaks. |

|
|
||||||||||||||||||||||||||||
|
Initiate connection of n svc_handlers to peers at remote_addrs using synch_options. Returns -1 if failure occurs and 0 otherwise. If failed_svc_handlers is non-NULL, a 1 is placed in the corresponding index of for each <svc_handlers[i]> that failed to connect, else a 0 is placed in that index. |

Bridge method for connecting the svc_handler to the remote_addr. The default behavior delegates to the <PEER_CONNECTOR::connect>. Reimplemented in ACE_Strategy_Connector< SVC_HANDLER, >. |

Initialize Svc_Handler.
Implements ACE_Connector_Base< SVC_HANDLER >. |
|
||||||||||
|
Bridge method for creating a SVC_HANDLER. The default is to create a new SVC_HANDLER only if == 0, else 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, >. |
|

Return the handle set representing the non-blocking connects in progress. Implements ACE_Connector_Base< SVC_HANDLER >. Referenced by ACE_Connector< SVC_HANDLER, ACE_PEER_CONNECTOR_2 >::close(). |
