Constants

const GroupedByFieldName = "groupedBy"

GroupedByFieldName is a special graphQL field that appears alongside the to-be-aggregated props, but doesn't require any processing by the connectors itself, as it just displays meta info about the overall aggregation.

Types

type ModulesProvider

type ModulesProvider interface {
	AggregateArguments(class *models.Class) map[string]*graphql.ArgumentConfig
	ExtractSearchParams(arguments map[string]interface{}, className string) map[string]interface{}
}

type RequestsLog

type RequestsLog interface {
	Register(requestType string, identifier string)
}

RequestsLog is a local abstraction on the RequestsLog that needs to be provided to the graphQL API in order to log Local.Get queries.

type Resolver

type Resolver interface {
	Aggregate(ctx context.Context, principal *models.Principal, info *aggregation.Params) (interface{}, error)
}

Resolver is a local interface that can be composed with other interfaces to form the overall GraphQL API main interface. All data-base connectors that want to support the Meta feature must implement this interface.
