Synopsis

Documentation

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.

clearList :: DoubleLinkedList a -> IO () Source #

Clear the contents of the list.

freezeList :: DoubleLinkedList a -> IO [a] Source #

Freeze the list and return its contents.
