Exact lookup

1. lookupAs' :: forall k (c :: Type -> Type) a . (PMapKey k, NonEmptyLike c, PMapValue k ~ Maybe a, FromGraphSON a) => k -> PMap c GValue -> Either PMapLookupException (Maybe a)

   greskell	Data.Greskell.Extra

   Similar to lookupAs, but this function converts a null result into Nothing. A null result is either (1) the key k is not found in the map, or (2) the key is found, but the value is null.

2. lookupListAs :: forall k (c :: Type -> Type) a . (PMapKey k, NonEmptyLike c, PMapValue k ~ a, FromGraphSON a) => k -> PMap c GValue -> Either PMapLookupException (NonEmpty a)

   greskell	Data.Greskell.Extra

   Look up the values and parse them into a.

3. lookupListAs' :: forall k (c :: Type -> Type) a . (PMapKey k, NonEmptyLike c, PMapValue k ~ Maybe a, FromGraphSON a) => k -> PMap c GValue -> Either PMapLookupException [Maybe a]

   greskell	Data.Greskell.Extra

   Similar to lookupListAs, but this function accepts null results. If the key k is not found in the map, it returns an empty list. If the key k is found and nulls are included in the values, they are obtained as Nothing.

4. lookupList :: PropertyMap m => Text -> m p v -> [p v]

   greskell	Data.Greskell.Graph.PropertyMap

   Look up all properties associated with the given key.

5. lookupListValues :: forall m (p :: Type -> Type) v . (PropertyMap m, Property p) => Text -> m p v -> [v]

   greskell	Data.Greskell.Graph.PropertyMap

   Lookup a list of property values from a PropertyMap by key.

6. lookupOne :: PropertyMap m => Text -> m p v -> Maybe (p v)

   greskell	Data.Greskell.Graph.PropertyMap

   Look up a property associated with the given key.

7. lookupOneValue :: forall m (p :: Type -> Type) v . (PropertyMap m, Property p) => Text -> m p v -> Maybe v

   greskell	Data.Greskell.Graph.PropertyMap

   Lookup a property value from a PropertyMap by key.

8. lookupAs :: forall k (c :: Type -> Type) a . (PMapKey k, NonEmptyLike c, PMapValue k ~ a, FromGraphSON a) => k -> PMap c GValue -> Either PMapLookupException a

   greskell	Data.Greskell.PMap

   Lookup the value and parse it into a.

9. lookupAs' :: forall k (c :: Type -> Type) a . (PMapKey k, NonEmptyLike c, PMapValue k ~ Maybe a, FromGraphSON a) => k -> PMap c GValue -> Either PMapLookupException (Maybe a)

   greskell	Data.Greskell.PMap

   Similar to lookupAs, but this function converts a null result into Nothing. A null result is either (1) the key k is not found in the map, or (2) the key is found, but the value is null.

10. lookupAsM :: forall k (c :: Type -> Type) a m . (PMapKey k, NonEmptyLike c, PMapValue k ~ a, FromGraphSON a, MonadThrow m) => k -> PMap c GValue -> m a

    greskell	Data.Greskell.PMap

    MonadThrow version of lookupAs.
