Detailed Description

template<typename T>
class CCheckQueue< T >

Queue for verifications that have to be performed.

The verifications are represented by a type T, which must provide an operator(), returning a bool.

One thread (the master) is assumed to push batches of verifications onto the queue, where they are processed by N-1 worker threads. When the master is done adding work, it temporarily joins the worker pool as an N'th worker, until all jobs are done.

Member Data Documentation

◆ condMaster

template<typename T >
boost::condition_variable CCheckQueue< T >::condMaster
private

Master thread blocks on this when out of work.

Definition at line 38 of file checkqueue.h.

◆ condWorker

template<typename T >
boost::condition_variable CCheckQueue< T >::condWorker
private

Worker threads block on this when out of work.

Definition at line 35 of file checkqueue.h.

◆ fAllOk

template<typename T >
bool CCheckQueue< T >::fAllOk
private

The temporary evaluation result.

Definition at line 51 of file checkqueue.h.

◆ mutex

template<typename T >
boost::mutex CCheckQueue< T >::mutex
private

Mutex to protect the inner state.

Definition at line 32 of file checkqueue.h.

◆ nBatchSize

template<typename T >
unsigned int CCheckQueue< T >::nBatchSize
private

The maximum number of elements to be processed in one batch.

Definition at line 61 of file checkqueue.h.

◆ nIdle

template<typename T >
int CCheckQueue< T >::nIdle
private

The number of workers (including the master) that are idle.

Definition at line 45 of file checkqueue.h.

◆ nTodo

template<typename T >
unsigned int CCheckQueue< T >::nTodo
private

Number of verifications that haven't completed yet.

This includes elements that are not anymore in queue, but still in worker's own batches.

Definition at line 58 of file checkqueue.h.

◆ nTotal

template<typename T >
int CCheckQueue< T >::nTotal
private

The total number of workers (including the master).

Definition at line 48 of file checkqueue.h.

◆ queue

template<typename T >
std::vector<T> CCheckQueue< T >::queue
private

The queue of elements to be processed.

As the order of booleans doesn't matter, it is used as a LIFO (stack)
