# Unique-keyed mappings

data UniqFM (key :: k) ele Source #

A finite map from `uniques` of one type to elements in another type.

The key is just here to keep us honest. It's always safe to use a single type as key. If two types don't overlap in their uniques it's also safe to index the same map at multiple key types. But this is very much discouraged.

addListToUFM_C :: Uniquable key => (elt -> elt -> elt) -> UniqFM key elt -> [(key, elt)] -> UniqFM key elt Source #

delFromUFM_Directly :: forall {k} (key :: k) elt. UniqFM key elt -> Unique -> UniqFM key elt Source #

delListFromUFM :: Uniquable key => UniqFM key elt -> [key] -> UniqFM key elt Source #

plusUFM :: forall {k} (key :: k) elt. UniqFM key elt -> UniqFM key elt -> UniqFM key elt Source #

plusUFM_C :: forall {k} elt (key :: k). (elt -> elt -> elt) -> UniqFM key elt -> UniqFM key elt -> UniqFM key elt Source #

plusUFM_CD :: forall {k} elta eltb eltc (key :: k). (elta -> eltb -> eltc) -> UniqFM key elta -> elta -> UniqFM key eltb -> eltb -> UniqFM key eltc Source #

`plusUFM_CD f m1 d1 m2 d2` merges the maps using `f` as the combinding function and `d1` resp. `d2` as the default value if there is no entry in `m1` reps. `m2`. The domain is the union of the domains of `m1` and `m2`.

IMPORTANT NOTE: This function strictly applies the modification function and forces the result unlike most the other functions in this module.

Representative example:

    plusUFM_CD f {A: 1, B: 2} 23 {B: 3, C: 4} 42
       == {A: f 1 42, B: f 2 3, C: f 23 4 }

plusUFM_CD2 :: forall {k} elta eltb eltc (key :: k). (Maybe elta -> Maybe eltb -> eltc) -> UniqFM key elta -> UniqFM key eltb -> UniqFM key eltc Source #

`plusUFM_CD2 f m1 m2` merges the maps using `f` as the combining function. Unlike `plusUFM_CD`, a missing value is not defaulted: it is instead passed as `Nothing` to `f`. `f` can never have both its arguments be `Nothing`.

IMPORTANT NOTE: This function strictly applies the modification function and forces the result.

`plusUFM_CD2 f m1 m2` is the same as `plusUFM_CD f (mapUFM Just m1) Nothing (mapUFM Just m2) Nothing`.

minusUFM_C :: forall {k} elt1 elt2 (key :: k). (elt1 -> elt2 -> Maybe elt1) -> UniqFM key elt1 -> UniqFM key elt2 -> UniqFM key elt1 Source #

`minusUFC_C f map1 map2` returns `map1`, except that every mapping `key |-> value1` in `map1` that shares a key with a mapping `key |-> value2` in `map2` is altered by `f`: `value1` is replaced by `f value1 value2`, where `Just` means that the new value is used and `Nothing` means that the mapping is deleted.

diffUFM :: forall {k} a (key :: k). Eq a => UniqFM key a -> UniqFM key a -> UniqFM key (Edit a) Source #

Computes the diff of two `UniqFM`s in terms of `Edit`s. Equal points will not be present in the result map at all.

nonDetFoldUFM :: forall {k} elt a (key :: k). (elt -> a -> a) -> a -> UniqFM key elt -> a Source #

Fold over a `UniqFM`.

Non-deterministic, unless the folding function is commutative (i.e. `a1 `f` ( a2 `f` b ) == a2 `f` ( a1 `f` b )` for all `a1`, `a2`, `b`).

unsafeCastUFMKey :: forall {k1} {k2} (key1 :: k1) elt (key2 :: k2). UniqFM key1 elt -> UniqFM key2 elt Source #

Cast the key domain of a UniqFM.

As long as the domains don't overlap in their uniques this is safe.

pprUniqFM :: forall {k} a (key :: k). (a -> SDoc) -> UniqFM key a -> SDoc Source #

pprUFM Source #

Arguments

:: forall {k} (key :: k) a. UniqFM key a | The things to be pretty printed
-> ([a] -> SDoc) | The pretty printing function to use on the elements
-> SDoc | `SDoc` where the things have been pretty printed

Pretty-print a non-deterministic set. The order of variables is non-deterministic and for pretty-printing that shouldn't be a problem. Having this function helps contain the non-determinism created with nonDetEltsUFM.

pprUFMWithKeys Source #

Arguments

:: forall {k} (key :: k) a. UniqFM key a | The things to be pretty printed
-> ([(Unique, a)] -> SDoc) | The pretty printing function to use on the elements
-> SDoc | `SDoc` where the things have been pretty printed

Pretty-print a non-deterministic set. The order of variables is non-deterministic and for pretty-printing that shouldn't be a problem. Having this function helps contain the non-determinism created with nonDetUFMToList.

pluralUFM :: forall {k} (key :: k) a. UniqFM key a -> SDoc Source #

Determines the pluralisation suffix appropriate for the length of a set in the same way that plural from Outputable does for lists.
