Control.Concurrent.STM.TArray

Description

TArrays: transactional arrays, for use in the STM monad

Synopsis

Documentation

data TArray i e #

TArray is a transactional array, supporting the usual MArray interface for mutable arrays.

It is currently implemented as Array ix (TVar e), but it may be replaced by a more efficient implementation in the future (the interface will remain the same, however).

Instances

MArray TArray e STM #
Methods getBounds :: Ix i => TArray i e -> STM (i, i) # getNumElements :: Ix i => TArray i e -> STM Int newArray :: Ix i => (i, i) -> e -> STM (TArray i e) # newArray_ :: Ix i => (i, i) -> STM (TArray i e) # unsafeNewArray_ :: Ix i => (i, i) -> STM (TArray i e) unsafeRead :: Ix i => TArray i e -> Int -> STM e unsafeWrite :: Ix i => TArray i e -> Int -> e -> STM ()
Ix i => Eq (TArray i e) #
Methods (==) :: TArray i e -> TArray i e -> Bool # (/=) :: TArray i e -> TArray i e -> Bool #
