Detailed Description

template<class SVC_HANDLER, ACE_PEER_CONNECTOR_1>
class ACE_Connector< SVC_HANDLER, >

Generic factory for actively connecting clients and creating service handlers (SVC_HANDLERs).

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 passively establishes connections. The SVC_HANDLER is instantiated with a concrete type that performs the application-specific service. An ACE_Connector inherits from ACE_Service_Object, which in turn inherits from ACE_Event_Handler. This enables the ACE_Reactor to dispatch the ACE_Connector's handle_output method when connections complete asynchronously. The handle_output method performs the connector's active connection establishment and service activation strategy.

Constructor & Destructor Documentation

template<class SVC_HANDLER, ACE_PEER_CONNECTOR_1 >
ACE_Connector< SVC_HANDLER, >::ACE_Connector ACE_Reactor   r = ACE_Reactor::instance(),
int    flags = 0
 

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 >
virtual ACE_Connector< SVC_HANDLER, >::~ACE_Connector void    [virtual]
 

Shutdown a connector and release resources.


Member Function Documentation

template<class SVC_HANDLER, ACE_PEER_CONNECTOR_1 >
virtual int ACE_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 in ACE_Strategy_Connector.

Referenced by ACE_Connector< SVC_HANDLER, ACE_PEER_CONNECTOR_2 >::connect_i, and ACE_Connector< SVC_HANDLER, ACE_PEER_CONNECTOR_2 >::handle_output.

template<class SVC_HANDLER, ACE_PEER_CONNECTOR_1 >
virtual int ACE_Connector< SVC_HANDLER, >::cancel SVC_HANDLER *    svc_handler [virtual]
 

Cancel a <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 <cancel> to decide the fate of the <svc_handler>.

template<class SVC_HANDLER, ACE_PEER_CONNECTOR_1 >
int ACE_Connector< SVC_HANDLER, >::cleanup_AST ACE_HANDLE    handle,
AST *&    ast
[protected]
 

Cleanup the <handler_map_> and returns the appropriate ACE_Svc_Tuple (which is 0 if there is no associated tuple).

Referenced by ACE_Connector< SVC_HANDLER, ACE_PEER_CONNECTOR_2 >::cancel, ACE_Connector< SVC_HANDLER, ACE_PEER_CONNECTOR_2 >::handle_close, ACE_Connector< SVC_HANDLER, ACE_PEER_CONNECTOR_2 >::handle_input, ACE_Connector< SVC_HANDLER, ACE_PEER_CONNECTOR_2 >::handle_output, and ACE_Connector< SVC_HANDLER, ACE_PEER_CONNECTOR_2 >::handle_timeout.

template<class SVC_HANDLER, ACE_PEER_CONNECTOR_1 >
virtual int ACE_Connector< SVC_HANDLER, >::close void    [virtual]
 

Close down the Connector.

Reimplemented in ACE_Strategy_Connector.

template<class SVC_HANDLER, ACE_PEER_CONNECTOR_1 >
virtual int ACE_Connector< SVC_HANDLER, >::connect SVC_HANDLER *&    svc_handler_hint,
SVC_HANDLER *&    svc_handler,

const ACE_PEER_CONNECTOR_ADDR &    local_addr = (ACE_TYPENAME_ACE_PEER_CONNECTOR_PEER_ADDR &) ACE_PEER_CONNECTOR_ADDR_ANY,
int    reuse_addr = 0,
int    flags = O_RDWR,
int    perms = 0
[virtual]
 

This is a variation on the previous <connect> 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 <close> hook on the <svc_handler> will be called automatically to prevent resource leaks.

template<class SVC_HANDLER, ACE_PEER_CONNECTOR_1 >
virtual int ACE_Connector< SVC_HANDLER, >::connect SVC_HANDLER *&    svc_handler,
const ACE_PEER_CONNECTOR_ADDR &    remote_addr,
const ACE_Synch_Options   synch_options = ACE_Synch_Options::defaults,
const ACE_PEER_CONNECTOR_ADDR &    local_addr = (ACE_TYPENAME_ACE_PEER_CONNECTOR_PEER_ADDR &) ACE_PEER_CONNECTOR_ADDR_ANY,
int    reuse_addr = 0,
int    flags = O_RDWR,
int    perms = 0
[virtual]
 

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 <close> hook on the <svc_handler> will be called automatically to prevent resource leaks.

[virtual]
 

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 <failed_svc_handler> for each <svc_handlers[i]> that failed to connect, else a 0 is placed in that index.
