ForSyDe.Shallow.Utility.Queue

This provides two data types, that can be used to model queue structures, such as FIFOs. There is a data type for an queue of infinite size Queue and one for finite size FiniteQueue.

Documentation

data Queue a

A queue is modeled as a list. The data type Queue modelles an queue of infinite size.

Constructors

Q [a]

Instances

Eq a => Eq (Queue a)

Defined in ForSyDe.Shallow.Utility.Queue

Methods

(==) :: Queue a -> Queue a -> Bool

(/=) :: Queue a -> Queue a -> Bool

Show a => Show (Queue a)

Defined in ForSyDe.Shallow.Utility.Queue

Methods

showsPrec :: Int -> Queue a -> ShowS

show :: Queue a -> String

showList :: [Queue a] -> ShowS

data FiniteQueue a

The data type FiniteQueue has an additional parameter, that determines the size of the queue.

Constructors

FQ Int [a]

Instances

Eq a => Eq (FiniteQueue a)

Defined in ForSyDe.Shallow.Utility.Queue

Methods

(==) :: FiniteQueue a -> FiniteQueue a -> Bool

(/=) :: FiniteQueue a -> FiniteQueue a -> Bool

Show a => Show (FiniteQueue a)

Defined in ForSyDe.Shallow.Utility.Queue

Methods

showsPrec :: Int -> FiniteQueue a -> ShowS

show :: FiniteQueue a -> String

showList :: [FiniteQueue a] -> ShowS

pushQ :: Queue a -> a -> Queue a

pushQ pushes one element into an infinite queue.

pushListQ :: Queue a -> [a] -> Queue a

pushListQ pushes a list of elements into an infinite queue.

popQ :: Queue a -> (Queue a, AbstExt a)

popQ pops one element from an infinite queue.

queue :: [a] -> Queue a

queue transforms a list into an infinite queue.

pushFQ :: FiniteQueue a -> a -> FiniteQueue a

pushFQ pushes one element into a finite queue.

pushListFQ :: FiniteQueue a -> [a] -> FiniteQueue a

pushListFQ pushes a list of elements into a finite queue.

popFQ :: FiniteQueue a -> (FiniteQueue a, AbstExt a)

popFQ pops one element from a finite queue.

finiteQueue :: Int -> [a] -> FiniteQueue a

finiteQueue transforms a list into an infinite queue.
