data TPred m a where

Type representing future-time linear temporal logic with until and next.

Constructors

Prop :: MSF m a Bool -> TPred m a

And :: TPred m a -> TPred m a -> TPred m a

Or :: TPred m a -> TPred m a -> TPred m a

Not :: TPred m a -> TPred m a

Implies :: TPred m a -> TPred m a -> TPred m a

Always :: TPred m a -> TPred m a

Eventually :: TPred m a -> TPred m a

Next :: TPred m a -> TPred m a

Until :: TPred m a -> TPred m a -> TPred m a

tPredMap

Arguments

:: Monad m

=> (MSF m a Bool -> m (MSF m a Bool))

Transformation to apply

-> TPred m a

Temporal predicate

-> m (TPred m a)

Apply a transformation to the leaves of a temporal predicate (to the SFs).

evalT :: Monad m => TPred (ReaderT DTime m) a -> SignalSampleStream a -> m Bool

Evaluates a temporal predicate at time T=0 against a sample stream.

Returns True if the temporal proposition is currently true.
