MetricFunctionTypes
- class great_expectations.core.metric_function_types.MetricFunctionTypes(value)#
Enum type, whose members depict the nature of return value of a metric implementation function (defined for a specified “ExecutionEngine” subclass) that is the final result (rather than a Callable for deferred execution).
The available types are:
VALUE – metric implementation function returns a value computed over a dataset represented by “Domain” (e.g., a statistic on column row values). This is the only value in use (others below have never been used and are thus deprecated).
MAP_VALUES (never used and deprecated) – metric implementation function returns a mapping between every “Domain” value and the result of a transformation of the corresponding “Domain” value.
WINDOW_VALUES (never used and deprecated) – metric implementation function returns the result of applying a specified windowing operation over “Domain” values.
AGGREGATE_VALUE (never used and deprecated) – metric implementation function returns the result of applying a specified aggregation operation to every “Domain” value.
- VALUE = 'value'#
