Constructor & Destructor Documentation

◆ MultiProducerSide()

std::size_t capacity )
inline

Definition at line 474 of file queue.hpp.

Member Function Documentation

◆ Create()

static std::shared_ptr< GenericQueue > concurrent::GenericQueue< T, QueuePolicy >::Create ( std::size_t max_size = kUnbounded)
inlinestatic

Create a new queue.

Definition at line 191 of file queue.hpp.

◆ GetConsumer()

Consumer concurrent::GenericQueue< T, QueuePolicy >::GetConsumer ( )
inline

Get a Consumer which makes it possible to read items from the queue. Can be called multiple times. The resulting Consumer is not thread-safe, so you have to use multiple Consumers of the same queue to simultaneously write from multiple coroutines/threads.

Note
Consumer may outlive the queue and producers.

Definition at line 227 of file queue.hpp.

◆ GetMultiConsumer()

MultiConsumer concurrent::GenericQueue< T, QueuePolicy >::GetMultiConsumer ( )
inline

Get a MultiConsumer which makes it possible to read items from the queue. Can be called multiple times. The resulting MultiConsumer is thread-safe, so it can be used simultaneously from multiple coroutines/threads.

Note
MultiConsumer may outlive the queue and producers.
Prefer Consumer tokens when possible, because MultiConsumer token incurs some overhead.

Definition at line 241 of file queue.hpp.

◆ GetMultiProducer()

MultiProducer concurrent::GenericQueue< T, QueuePolicy >::GetMultiProducer ( )
inline

Get a MultiProducer which makes it possible to push items into the queue. Can be called multiple times. The resulting MultiProducer is thread-safe, so it can be used simultaneously from multiple coroutines/threads.

Note
MultiProducer may outlive the queue and consumers.
Prefer Producer tokens when possible, because MultiProducer token incurs some overhead.

Definition at line 215 of file queue.hpp.

◆ GetProducer()

Producer concurrent::GenericQueue< T, QueuePolicy >::GetProducer ( )
inline

Get a Producer which makes it possible to push items into the queue. Can be called multiple times. The resulting Producer is not thread-safe, so you have to use multiple Producers of the same queue to simultaneously write from multiple coroutines/threads.

Note
Producer may outlive the queue and consumers.

Definition at line 201 of file queue.hpp.

◆ GetSizeApproximate() [1/2]

std::size_t concurrent::GenericQueue< T, QueuePolicy >::GetSizeApproximate ( ) const
inline

Gets the approximate size of queue.

Definition at line 255 of file queue.hpp.

◆ GetSizeApproximate() [2/2]

template<typename T, typename QueuePolicy>
std::size_t concurrent::GenericQueue< T, QueuePolicy >::MultiProducerSide::GetSizeApproximate ( ) const
inlinenoexcept

Definition at line 498 of file queue.hpp.

◆ GetSoftMaxSize() [1/2]

std::size_t concurrent::GenericQueue< T, QueuePolicy >::GetSoftMaxSize ( ) const
inline

Gets the limit on the queue size.

Definition at line 252 of file queue.hpp.

◆ GetSoftMaxSize() [2/2]

template<typename T, typename QueuePolicy>
std::size_t concurrent::GenericQueue< T, QueuePolicy >::MultiProducerSide::GetSoftMaxSize ( ) const
inlinenoexcept

Definition at line 500 of file queue.hpp.

◆ OnElementPopped()

template<typename T, typename QueuePolicy>
void concurrent::GenericQueue< T, QueuePolicy >::MultiProducerSide::OnElementPopped ( std::size_t value_size)
inline

Definition at line 490 of file queue.hpp.

◆ Push()

template<typename T, typename QueuePolicy>
template<typename Token>
bool concurrent::GenericQueue< T, QueuePolicy >::MultiProducerSide::Push ( Token & token,
T && value,
engine::Deadline deadline,
std::size_t value_size )
inlinenodiscard

Definition at line 480 of file queue.hpp.

◆ PushNoblock()

template<typename T, typename QueuePolicy>
template<typename Token>
bool concurrent::GenericQueue< T, QueuePolicy >::MultiProducerSide::PushNoblock ( Token & token,
T && value,
std::size_t value_size )
inlinenodiscard

Definition at line 486 of file queue.hpp.

◆ ResumeBlockingOnPush()

template<typename T, typename QueuePolicy>
void concurrent::GenericQueue< T, QueuePolicy >::MultiProducerSide::ResumeBlockingOnPush ( )
inline

Definition at line 494 of file queue.hpp.

◆ SetSoftMaxSize() [1/2]

template<typename T, typename QueuePolicy>
void concurrent::GenericQueue< T, QueuePolicy >::MultiProducerSide::SetSoftMaxSize ( std::size_t count)
inline

Definition at line 496 of file queue.hpp.

◆ SetSoftMaxSize() [2/2]

void concurrent::GenericQueue< T, QueuePolicy >::SetSoftMaxSize ( std::size_t max_size)
inline

Sets the limit on the queue size, pushes over this limit will block.

Note
This is a soft limit and may be slightly overrun under load.

Definition at line 249 of file queue.hpp.

◆ StopBlockingOnPush()

template<typename T, typename QueuePolicy>
void concurrent::GenericQueue< T, QueuePolicy >::MultiProducerSide::StopBlockingOnPush ( )
inline
