class Equivalent a whereSource
Comparisons for equivalency. Two items are equivalent if they have the same semantic meaning, even if the data in the two items is different.
equivalent :: a -> a -> BoolSource
compareEv :: a -> a -> OrderingSource
Compares based on equivalency.
Equivalent SpaceBetween | |
Equivalent Side | |
Equivalent Tags | Tags are equivalent if they have the same tags (even if in a different order). |
Equivalent DateTime | |
Equivalent Qty | |
Equivalent QtyRep | |
Equivalent Price | Two Price are equivalent if the From and To are equal and the CountPerUnit is equivalent. |
Equivalent CountPerUnit | |
Equivalent PostingCore | Two PostingCore are equivalent if the Tags are equivalent and the other data is equal, exlucing the Side and the SpaceBetween, which are not considered at all. |
Equivalent TopLineCore | TopLineCore are equivalent if their dates are equivalent and if everything else is equal. |
Equivalent PricePoint | PricePoint are equivalent if the dateTime and the Price are equivalent. Other elements of the PricePoint are ignored. |
Equivalent a => Equivalent (Maybe a) | |
Equivalent q => Equivalent (Entry q) | |
Equivalent q => Equivalent (Amount q) | |
Equivalent m => Equivalent (Ents m) | Ents are equivalent if the content Ents of each are equivalent. The order of the ents is insignificant. |
Equivalent m => Equivalent (Ent m) | Two Ents are equivalent if the entries are equivalent and the metadata is equivalent (whether the Ent is inferred or not is ignored.) |
(Equivalent a, Equivalent b) => Equivalent (Either a b) | |
(Equivalent a, Equivalent b) => Equivalent (a, b) | |
(Equivalent a, Equivalent b, Equivalent c) => Equivalent (a, b, c) |
