This module defines a plain and more fast version of an updatable and strict reference that depends on the event queue but that doesn't supply with the signal notification.
Synopsis
Documentation
class Monad m => MonadRef m where Source #
A monad within which we can create mutable references.
newRef :: a -> Simulation m (Ref m a) Source #
Create a new reference.
readRef :: Ref m a -> Event m a Source #
Read the value of a reference.
writeRef :: Ref m a -> a -> Event m () Source #
Write a new value into the reference.
modifyRef :: Ref m a -> (a -> a) -> Event m () Source #
Mutate the contents of the reference.
equalRef :: Ref m a -> Ref m a -> Bool Source #
Compare two references for equality.

class MonadRef m => MonadRef0 m where Source #
A kind of reference that can be created within more low level computation than Simulation
.
newRef0 :: a -> m (Ref m a) Source #
Create a new reference within more low level computation than Simulation
