virtual uint32_t  getSize () const =0 
 Returns the number of events in the queue. More...


virtual const Event *  getEvent (uint32_t index) const =0

virtual const Event* Argus::IEventQueue::getEvent 
( 
uint32_t 
index  ) 
const 

pure virtual 
Returns the event with the given index, where index 0 corresponds to the oldest event and [getSize()  1] is the newest.
The returned event is not removed from the queue. If index is not in [0, getSize()1], NULL is returned.
virtual Status Argus::IEventQueue::getEventTypes 
( 
std::vector< EventType > * 
types  ) 
const 

pure virtual 
Returns the event types that this queue will receive.
 Parameters

[out]  types  This vector will be populated with the event types registered to this queue. 
 Returns
 success/status of the call.
virtual const Event* Argus::IEventQueue::getNextEvent 
( 
 ) 


pure virtual 
Returns the next event in the queue (that is, the event at index 0).
The returned event will be removed from the queue, though the object will remain valid according to the rules described by waitForEvents(). If the queue is empty, returns NULL.
virtual uint32_t Argus::IEventQueue::getSize 
( 
 ) 
const 

pure virtual 
Returns the number of events in the queue.
