Provides an interface to timers.

This is an abstract base class that provides hook for implementing specialized policies such as <ace_timer_list> and <ace_timer_heap>.

## Member Typedef Documentation

template<class TYPE, class FUNCTOR, class ACE_LOCK>
typedef ACE_Timer_Queue_Iterator_T<TYPE, FUNCTOR, ACE_LOCK> ACE_Timer_Queue_T< TYPE, FUNCTOR, ACE_LOCK >::ITERATOR

| Type of Iterator.

## Constructor & Destructor Documentation

template<class TYPE, class FUNCTOR, class ACE_LOCK>
ACE_Timer_Queue_T< TYPE, FUNCTOR, ACE_LOCK >::ACE_Timer_Queue_T | ( | FUNCTOR * | upcall_functor = `0`,
|  | ACE_Free_List< ACE_Timer_Node_T< TYPE > > * | freelist = `0`
| ) |

| Default constructor. <upcall_functor> is the instance of the FUNCTOR to be used by the queue. If <upcall_functor> is 0, Timer Queue will create a default FUNCTOR. <freelist> the freelist of timer nodes. If 0, then a default freelist will be created.

template<class TYPE, class FUNCTOR, class ACE_LOCK>
ACE_Timer_Queue_T< TYPE, FUNCTOR, ACE_LOCK >::~ACE_Timer_Queue_T | ( | void |  | ) | `[virtual]`

| Destructor - make virtual for proper destruction of inherited classes.

template<class TYPE, class FUNCTOR, class ACE_LOCK>
ACE_Timer_Queue_T< TYPE, FUNCTOR, ACE_LOCK >::ACE_Timer_Queue_T | ( | const ACE_Timer_Queue_T< TYPE, FUNCTOR, ACE_LOCK > & |  | ) | `[private]`

## Member Function Documentation

template<class TYPE, class FUNCTOR, class ACE_LOCK>
ACE_Timer_Node_T< TYPE > * ACE_Timer_Queue_T< TYPE, FUNCTOR, ACE_LOCK >::alloc_node | ( | void |  | ) | `[protected, virtual]`

| Factory method that allocates a new node. Reimplemented in ACE_Timer_Heap_T< TYPE, FUNCTOR, ACE_LOCK >.

template<class TYPE, class FUNCTOR, class ACE_LOCK>
ACE_Time_Value * ACE_Timer_Queue_T< TYPE, FUNCTOR, ACE_LOCK >::calculate_timeout | ( | ACE_Time_Value * | max,
|  | ACE_Time_Value * | the_timeout
| ) | `[virtual]`

| Determine the next event to timeout. Returns <max> if there are no pending timers or if all pending timers are longer than max. <the_timeout> should be a pointer to storage for the timeout value, and this value is also returned. This method does not acquire a lock internally since it doesn't modify internal state. If you need to call this method when the queue is being modified concurrently, however, you should make sure to acquire the <mutex()> externally before making the call.

template<class TYPE, class FUNCTOR, class ACE_LOCK>
ACE_Time_Value * ACE_Timer_Queue_T< TYPE, FUNCTOR, ACE_LOCK >::calculate_timeout | ( | ACE_Time_Value * | max | ) | `[virtual]`

| Determine the next event to timeout. Returns <max> if there are no pending timers or if all pending timers are longer than max. This method acquires a lock internally since it modifies internal state.

template<class TYPE, class FUNCTOR, class ACE_LOCK>
virtual int ACE_Timer_Queue_T< TYPE, FUNCTOR, ACE_LOCK >::cancel | ( | long | timer_id,
|  | const void ** | act = `0`,
|  | int | dont_call_handle_close = `1`
| ) | `[pure virtual]`

| Cancel the single timer that matches the <timer_id> value (which was returned from the <schedule> method). If act is non-NULL then it will be set to point to the ``magic cookie'' argument passed in when the timer was registered. This makes it possible to free up the memory and avoid memory leaks. If <dont_call_handle_close> is 0 then the <functor> will be invoked, which typically calls the <handle_close> hook. Returns 1 if cancellation succeeded and 0 if the <timer_id> wasn't found. Implemented in ACE_Timer_Hash_T< TYPE, FUNCTOR, ACE_LOCK, BUCKET >, ACE_Timer_Heap_T< TYPE, FUNCTOR, ACE_LOCK >, ACE_Timer_List_T< TYPE, FUNCTOR, ACE_LOCK >, and ACE_Timer_Wheel_T< TYPE, FUNCTOR, ACE_LOCK >.

virtual int ACE_Timer_Queue_T< TYPE, FUNCTOR, ACE_LOCK >::cancel | ( | const TYPE & | type,
|  | int | dont_call_handle_close = `1`
| ) | `[pure virtual]`

| Cancel all timer associated with <type>. If <dont_call_handle_close> is 0 then the <functor> will be invoked, which typically invokes the <handle_close> hook. Returns number of timers cancelled. Implemented in ACE_Timer_Hash_T< TYPE, FUNCTOR, ACE_LOCK, BUCKET >, ACE_Timer_Heap_T< TYPE, FUNCTOR, ACE_LOCK >, ACE_Timer_List_T< TYPE, FUNCTOR, ACE_LOCK >, and ACE_Timer_Wheel_T< TYPE, FUNCTOR, ACE_LOCK >.

template<class TYPE, class FUNCTOR, class ACE_LOCK>
int ACE_Timer_Queue_T< TYPE, FUNCTOR, ACE_LOCK >::dispatch_info | ( | const ACE_Time_Value & | current_time,
|  | ACE_Timer_Node_Dispatch_Info_T< TYPE > & | info
| ) | `[virtual]`

| Get the dispatch information for a timer whose value is <= <cur_time>. This does not account for <timer_skew>. Returns 1 if there is a node whose value <= <cur_time> else returns a 0.

template<class TYPE, class FUNCTOR, class ACE_LOCK>
int ACE_Timer_Queue_T< TYPE, FUNCTOR, ACE_LOCK >::dispatch_info_i | ( | const ACE_Time_Value & | current_time,
|  | ACE_Timer_Node_Dispatch_Info_T< TYPE > & | info
| ) | `[protected, virtual]`

| Non-locking version of dispatch_info (). Reimplemented in ACE_Timer_Hash_T< TYPE, FUNCTOR, ACE_LOCK, BUCKET >.

template<class TYPE, class FUNCTOR, class ACE_LOCK>
void ACE_Timer_Queue_T< TYPE, FUNCTOR, ACE_LOCK >::dump | ( | void |  | ) | const`[virtual]`

| Dump the state of a object. Reimplemented in ACE_Timer_Hash_T< TYPE, FUNCTOR, ACE_LOCK, BUCKET >, ACE_Timer_Heap_T< TYPE, FUNCTOR, ACE_LOCK >, ACE_Timer_List_T< TYPE, FUNCTOR, ACE_LOCK >, and ACE_Timer_Wheel_T< TYPE, FUNCTOR, ACE_LOCK >.

template<class TYPE, class FUNCTOR, class ACE_LOCK>
virtual const ACE_Time_Value& ACE_Timer_Queue_T< TYPE, FUNCTOR, ACE_LOCK >::earliest_time | ( | void |  | ) | const`[pure virtual]`

| Returns the time of the earlier node in the Timer_Queue. Must be called on a non-empty queue. Implemented in ACE_Timer_Hash_T< TYPE, FUNCTOR, ACE_LOCK, BUCKET >, ACE_Timer_Heap_T< TYPE, FUNCTOR, ACE_LOCK >, ACE_Timer_List_T< TYPE, FUNCTOR, ACE_LOCK >, and ACE_Timer_Wheel_T< TYPE, FUNCTOR, ACE_LOCK >.

template<class TYPE, class FUNCTOR, class ACE_LOCK>
ACE_INLINE int ACE_Timer_Queue_T< TYPE, FUNCTOR, ACE_LOCK >::expire | ( | void |  | ) |

| Run the <functor> for all timers whose values are <= <ACE_OS::gettimeofday>. Also accounts for <timer_skew>. Depending on the resolution of the underlying OS the system calls like select()/poll() might return at time different than that is specified in the timeout. Suppose the OS guarantees a resolution of t ms. The timeline will look like A B | | V V |-------------|-------------|-------------|-------------| t t t t t If you specify a timeout value of A, then the timeout will not occur at A but at the next interval of the timer, which is later than that is expected. Similarly, if your timeout value is equal to B, then the timeout will occur at interval after B. Now depending upon the resolution of your timeouts and the accuracy of the timeouts needed for your application, you should set the value of <timer_skew>. In the above case, if you want the timeout A to fire no later than A, then you should specify your <timer_skew> to be A t. The timeout value should be specified via the macro ACE_TIMER_SKEW in your config.h file. The default value is zero. Things get interesting if the t before the timeout value B is zero i.e your timeout is less than the interval. In that case, you are almost sure of not getting the desired timeout behaviour. Maybe you should look for a better OS :-) Returns the number of timers canceled. Reimplemented in ACE_Timer_Hash_T< TYPE, FUNCTOR, ACE_LOCK, BUCKET >, and ACE_Timer_Wheel_T< TYPE, FUNCTOR, ACE_LOCK >.

template<class TYPE, class FUNCTOR, class ACE_LOCK>

virtual int ACE_Timer_Queue_T< TYPE, FUNCTOR, ACE_LOCK >::reset_interval | ( | long | timer_id,
|  | const ACE_Time_Value & | interval
| ) | `[pure virtual]`

| Resets the interval of the timer represented by <timer_id> to <interval>, which is specified in relative time to the current <gettimeofday>. If <interval> is equal to <ACE_Time_Value::zero>, the timer will become a non-rescheduling timer. Returns 0 if successful, -1 if not.

void ACE_Timer_Queue_T< TYPE, FUNCTOR, ACE_LOCK >::return_node | ( | ACE_Timer_Node_T< TYPE > * |  | ) | `[virtual]`

| Method used to return a timer node to the queue's ownership after it is returned by a method like <remove_first>.

template<class TYPE, class FUNCTOR, class ACE_LOCK>
long ACE_Timer_Queue_T< TYPE, FUNCTOR, ACE_LOCK >::schedule | ( | const TYPE & | type,
|  | const void * | act,

|  | const ACE_Time_Value & | interval = `ACE_Time_Value::zero`
| ) | `[virtual]`

| Schedule <type> that will expire at <future_time>, which is specified in absolute time. If it expires then <act> is passed in as the value to the <functor>. If <interval> is != to <ACE_Time_Value::zero> then it is used to reschedule the <type> automatically, using relative time to the current <gettimeofday>. This method returns a <timer_id> that uniquely identifies the the <type> entry in an internal list. This <timer_id> can be used to cancel the timer before it expires. The cancellation ensures that <timer_ids> are unique up to values of greater than 2 billion timers. As long as timers don't stay around longer than this there should be no problems with accidentally deleting the wrong timer. Returns -1 on failure (which is guaranteed never to be a valid <timer_id>).
