Threading::SafePriorityQueue< PRITYPE, TYPE > Class Template Reference

#include <safepriorityqueue.h>

Detailed Description

template<class PRITYPE, class TYPE>
class Threading::SafePriorityQueue< PRITYPE, TYPE >

A thread-safe priority-sorted queue which protects itself with critical sections.

Offers a method to wait for new elements to be added. Useful for inter-thread communications.

Signal()

template<class PRITYPE , class TYPE >

void Threading::SafePriorityQueue< PRITYPE, TYPE >::Signal

(

)

signal the internal event, so that Wait() will return

This signals the internal event object, on which Wait() may be waiting.

This method may be useful to wake up a thread waiting for events when it should stop.

(

)

const

returns number of elements in the queue

Wait()

template<class PRITYPE , class TYPE >

void Threading::SafePriorityQueue< PRITYPE, TYPE >::Wait

(

)

wait until queue contains at least one element
