This class provides a well-defined interface that the Acceptor and Connector pattern factories use as their target. Typically, client applications will subclass ACE_Svc_Handler and do all the interesting work in the subclass. One thing that the ACE_Svc_Handler does contain is a PEER_STREAM endpoint that is initialized by an ACE_Acceptor or ACE_Connector when a connection is established successfully. This endpoint is used to exchange data between a ACE_Svc_Handler and the peer it is connected with.

|
|
Constructor initializes the <thr_mgr> and <mq> by passing them down to the <ACE_Task> base class. The <reactor> is passed to the <ACE_Event_Handler>. |
|
Destructor.
|
|
When the svc_handle is no longer needed around as a hint, call this method. In addition, reset <*act_holder> to zero if <act_holder != 0>. |
|
Object termination hook -- application-specific cleanup code goes here. This function is called by the idle() function if the object does not have a ACE_Connection_Recycling_Strategy associated with it. Also, due to this class's derivation from <ACE_Task>, <close> is also called when a thread activated with this object exits. See <ACE_Task::close> for further details. The default action of this function is to call <handle_close> with the default arguments. Reimplemented from ACE_Task_Base. |
|
Call this to free up dynamically allocated <Svc_Handlers> (otherwise you will get memory leaks). In general, you should call this method rather than <delete> since this method knows whether or not the object was allocated dynamically, and can act accordingly (i.e., deleting it if it was allocated dynamically). |
|
Dump the state of an object.
Reimplemented from ACE_Task< ACE_SYNCH_USE >. Reimplemented in ACE_Buffered_Svc_Handler<, >. |
|
Default version does no work and returns -1. Must be overloaded by application developer to do anything meaningful. Reimplemented from ACE_Shared_Object. |
|
Get the underlying handle associated with the <peer_>.
Reimplemented from ACE_Event_Handler. |
|
Perform termination activities on the SVC_HANDLER. The default behavior is to close down the <peer_> (to avoid descriptor leaks) and to <destroy> this object (to avoid memory leaks)! If you don't want this behavior make sure you override this method... Reimplemented from ACE_Event_Handler. |
|
Default behavior when timeouts occur is to close down the <Svc_Handler> by calling <handle_close>. Reimplemented from ACE_Event_Handler. Reimplemented in ACE_Buffered_Svc_Handler<, >. |
|
Call this method if you want to recycling the <Svc_Handler> instead of closing it. If the object does not have a recycler, it will be closed. |
|
Default version does no work and returns -1. Must be overloaded by application developer to do anything meaningful. Reimplemented from ACE_Shared_Object. |

|
Activate the client handler. This is typically called by the <ACE_Acceptor> or <ACE_Connector>. Reimplemented from ACE_Task_Base. |
|
This operator is necessary to complement the class-specific operator new above. Unfortunately, it's not portable to all C++ compilers... |
|
This really should be private so that users are forced to call <destroy>. Unfortunately, the C++ standard doesn't allow there to be a public new and a private delete. It is a bad idea to call this method directly, so use <destroy> instead, unless you know for sure that you've allocated the object dynamically. |
|
This operator permits "placement new" on a per-object basis.
|
|
Overloaded new operator. This method unobtrusively records if a <Svc_Handler> is allocated dynamically, which allows it to clean itself up correctly whether or not it's allocated statically or dynamically. |
|
Returns the underlying PEER_STREAM. Used by <ACE_Acceptor::accept> and <ACE_Connector::connect> factories |
|
Upcall made by the recycler when it is about to recycle the connection. This gives the object a chance to prepare itself for recycling. Return 0 if the object is ready for recycling, -1 on failures. |
|
|
|
Call this method if you want to get/set the state of the <Svc_Handler>. If the object does not have a recycler, this call will have no effect (and the accessor will return ACE_RECYCLABLE_UNKNOWN). |
|
Get the recycler.
|
|
Set the recycler and the <recycling_act> that is used during purging and caching. |
|
Get the recycling act.
|
|
Set the underlying handle associated with the <peer_>.
Reimplemented from ACE_Event_Handler. |
|
Close down the descriptor and unregister from the Reactor.
|
|
Keeps track of whether we are in the process of closing (required to avoid circular calls to <handle_close>). |
|
Have we been dynamically created?
|
|
Maintain connection with client.
|
|
Pointer to the connection recycler.
|
|
Asynchronous Completion Token (ACT) to be used to when talking to the recycler. |
