MonadMultiState class

Description

The multi-valued version of mtl's MonadState

Synopsis

MonadMultiState class

class Monad m => MonadMultiGet a m where Source #

In contrast to MonadMultiReader, MonadMultiGet is defined for State too, so it corresponds to read-access of any kind.

Note however that for MultiRWS, only the values from the state part can be accessed via MonadMultiGet, due to limitations of the design of MultiRWS and of the type system. This is issue is resolved in the MultiGST type.
