Synopsis

data TVar a newTVar :: MonadAdvSTM m => a -> m (TVar a) newTVarIO :: a -> IO (TVar a) readTVar :: MonadAdvSTM m => TVar a -> m a writeTVar :: MonadAdvSTM m => TVar a -> a -> m ()

TVars

data TVar a Source

newTVar :: MonadAdvSTM m => a -> m (TVar a) Source

See newTVar

newTVarIO :: a -> IO (TVar a) Source

See newTVarIO

readTVar :: MonadAdvSTM m => TVar a -> m a Source

Reads a value from a TVar. Blocks until the IO onCommit action(s) of the corresponding transaction are complete. See onCommit for a more detailed description of this behaviour.

writeTVar :: MonadAdvSTM m => TVar a -> a -> m () Source

Writes a value to a TVar. Blocks until the onCommit IO-action(s) are complete. See onCommit for details.
