Data.IORef.Lifted

Description

This is a wrapped version of Data.IORef with types generalised from IO to all monads in MonadBase.

Synopsis

Documentation

data IORef a :: * -> * #

A mutable variable in the IO monad

Instances

Eq (IORef a)

Since: 4.1.0.0

Methods

(==) :: IORef a -> IORef a -> Bool #

(/=) :: IORef a -> IORef a -> Bool #

newIORef :: MonadBase IO m => a -> m (IORef a) Source #

Generalized version of newIORef.

readIORef :: MonadBase IO m => IORef a -> m a Source #

Generalized version of readIORef.

writeIORef :: MonadBase IO m => IORef a -> a -> m () Source #

Generalized version of writeIORef.

modifyIORef :: MonadBase IO m => IORef a -> (a -> a) -> m () Source #

Generalized version of modifyIORef.

modifyIORef' :: MonadBase IO m => IORef a -> (a -> a) -> m () Source #

Generalized version of modifyIORef'.

atomicModifyIORef :: MonadBase IO m => IORef a -> (a -> (a, b)) -> m b Source #

Generalized version of atomicModifyIORef.

atomicModifyIORef' :: MonadBase IO m => IORef a -> (a -> (a, b)) -> m b Source #

Generalized version of atomicModifyIORef'.

atomicWriteIORef :: MonadBase IO m => IORef a -> a -> m () Source #

Generalized version of atomicWriteIORef.

mkWeakIORef :: MonadBaseControl IO m => IORef a -> m () -> m (Weak (IORef a)) Source #

Generalized version of mkWeakIORef.

Note any monadic side effects in m of the "finalizer" computation are discarded.
