Instances

Monad Strategy

Strategy is a monad. TODO: Can we write this as a monad transformer?

MonadPlus Strategy

Show a => Show (Strategy a)

nullStrategy :: Strategy a -> Bool

liftFrequency :: Frequency a -> Strategy a

Strategy where only the actions from the given single frequency table can be picked.

(.|) :: Strategy a -> Strategy a -> Strategy a

Strategy with the actions from both argument strategies, with original frequencies.

reject :: Strategy a

Strategy with no actions at all.

(.=>) :: Bool -> Strategy a -> Strategy a

Conditionally accepted strategy.

only :: (a -> Bool) -> Strategy a -> Strategy a

Strategy with all actions not satisfying the predicate removed. The remaining actions keep their original relative frequency values.

bestVariant :: Strategy a -> Frequency a

When better choices are towards the start of the list, this is the best frequency of the strategy.

renameStrategy :: Text -> Strategy a -> Strategy a

Overwrite the description of all frequencies within the strategy.

returN :: Text -> a -> Strategy a

Like return, but pick a name of the single frequency.
