Documentation

class AggregationPredicatesSchema (b :: BackendType) where Source #

Backends implement this type class to specify the schema of aggregation predicates.

The default implementation results in a parser that does not parse anything.

The scope of this class is local to the function boolExp. In particular, methods in `class BackendSchema` and `type MonadBuildSchema` should *NOT* include this class as a constraint.
