- type Priority = Int
- queueNull :: PriorityQueue a -> IO Bool
- queueCount :: PriorityQueue a -> IO Int
- newQueue :: IO (PriorityQueue a)
- enqueue :: PriorityQueue a -> Double -> Priority -> a -> IO ()

Documentation
data PriorityQueue a Source #
The PriorityQueue type represents an imperative heap-based
priority queue.
queueCount :: PriorityQueue a -> IO Int Source #
Return the number of elements in the priority queue.
newQueue :: IO (PriorityQueue a) Source #
Create a new priority queue.
enqueue :: PriorityQueue a -> Double -> Priority -> a -> IO () Source #
Enqueue a new element with the specified priority.
dequeue :: PriorityQueue a -> IO () Source #
Dequeue the element with the minimal priority.
queueFront :: PriorityQueue a -> IO (Double, Priority, a) Source #
Return the element with the minimal priority.
