data DoubleLinkedList a Source
The DoubleLinkedList
type represents an imperative double-linked list.
listNull :: DoubleLinkedList a -> IO Bool Source
Test whether the list is empty.
listCount :: DoubleLinkedList a -> IO Int Source
Return the number of elements in the list.
newList :: IO (DoubleLinkedList a) Source
Create a new list.
listInsertFirst :: DoubleLinkedList a -> a -> IO () Source
Insert a new element in the beginning.
listAddLast :: DoubleLinkedList a -> a -> IO () Source
Add a new element to the end.
listRemoveFirst :: DoubleLinkedList a -> IO () Source
Remove the first element.
listRemoveLast :: DoubleLinkedList a -> IO () Source
Remove the last element.
listRemove :: Eq a => DoubleLinkedList a -> a -> IO Bool Source
Remove the specified element from the list and return a flag indicating whether the element was found and removed.
listRemoveBy :: DoubleLinkedList a -> (a -> Bool) -> IO (Maybe a) Source
Remove an element satisfying the specified predicate and return the element if found.
listContains :: Eq a => DoubleLinkedList a -> a -> IO Bool Source
Detect whether the specified element is contained in the list.
listContainsBy :: DoubleLinkedList a -> (a -> Bool) -> IO (Maybe a) Source
Detect whether an element satisfying the specified predicate is contained in the list.
listFirst :: DoubleLinkedList a -> IO a Source
Return the first element.
listLast :: DoubleLinkedList a -> IO a Source
Return the last element.
