- data StaticPriorities = StaticPriorities
Documentation
class Monad m => QueueStrategy m s where Source #
Defines the basic queue strategy.
Minimal complete definition
Methods
newStrategyQueue :: s -> Simulation m (StrategyQueue m s a) Source #
Create a new queue by the specified strategy.
strategyQueueNull :: StrategyQueue m s a -> Event m Bool Source #
Test whether the queue is empty.
class QueueStrategy m s => DequeueStrategy m s where Source #
Defines a strategy with support of the dequeuing operation.
Minimal complete definition
Methods
strategyDequeue :: StrategyQueue m s a -> Event m a Source #
Dequeue the front element and return it.
class DequeueStrategy m s => EnqueueStrategy m s where Source #
It defines a strategy when we can enqueue a single element.
Minimal complete definition
class DequeueStrategy m s => PriorityQueueStrategy m s p | s -> p where Source #
It defines a strategy when we can enqueue an element with the specified priority.
Minimal complete definition
Methods
strategyEnqueueWithPriority :: StrategyQueue m s a -> p -> a -> Event m () Source #
Enqueue an element with the specified priority.
class DequeueStrategy m s => DeletingQueueStrategy m s where Source #
Defines a strategy with support of the deleting operation.
Minimal complete definition
Methods
strategyQueueDelete :: Eq a => StrategyQueue m s a -> a -> Event m Bool Source #
Remove the element and return a flag indicating whether the element was found and removed.
strategyQueueDeleteBy :: StrategyQueue m s a -> (a -> Bool) -> Event m (Maybe a) Source #
Remove an element satisfying the predicate and return the element if found.
strategyQueueContains :: Eq a => StrategyQueue m s a -> a -> Event m Bool Source #
Detect whether the specified element is contained in the queue.
strategyQueueContainsBy :: StrategyQueue m s a -> (a -> Bool) -> Event m (Maybe a) Source #
Detect whether an element satifying the specified predicate is contained in the queue.
