Helper functions
mkUnknownFDef :: String -> FieldData a bSource
execGetter :: ConfigData -> b -> a -> FieldGetter a b -> ResultEntrySource
Main query execution
getSelectedFields :: FieldMap a b -> [String] -> FieldList a bSource
needsLiveData :: [FieldGetter a b] -> BoolSource
needsNames :: Query -> Maybe [FilterValue]Source
nameField :: ItemType -> FilterFieldSource
Computes the name field for different query types.
uuidField :: ItemType -> FilterFieldSource
Computes the uuid field, or the best possible substitute, for different query types.
getAllQuotedStrings :: [FilterValue] -> [String]Source
getRequestedNames :: Query -> [String]Source
Checks that we have either requested a valid set of names, or we have a more complex filter.
genericQuery :: FieldMap a b -> CollectorType a b -> (a -> String) -> (ConfigData -> Container a) -> (ConfigData -> String -> ErrorResult a) -> ConfigData -> Bool -> [String] -> Filter FilterField -> [String] -> IO (ErrorResult QueryResult)Source
Arguments
| :: ConfigData | The current configuration |
| -> Bool | Whether to collect live data |
| -> Query | The query (item, fields, filter) |
| -> IO (ErrorResult QueryResult) | Result |
Main query execution function.
dummyCollectLiveData :: Bool -> ConfigData -> [a] -> IO [(a, NoDataRuntime)]Source
queryInner :: ConfigData -> Bool -> Query -> [String] -> IO (ErrorResult QueryResult)Source
queryJobs :: ConfigData -> Bool -> [FilterField] -> Filter FilterField -> IO (ErrorResult QueryResult)Source
fieldsExtractor :: FieldMap a b -> [FilterField] -> QueryFieldsResultSource
queryFields :: QueryFields -> ErrorResult QueryFieldsResultSource
Query fields call.
queryCompat :: QueryResult -> ErrorResult [[JSValue]]Source
Classic query converter. It gets a standard query result on input and computes the classic style results.
