Properties

column ↔ String
Optional. The unnested column which this rule is evaluated against.
getter/setter pair
dimension ↔ String
Required. The dimension a rule belongs to. Results are also aggregated at the dimension level. Supported dimensions are "COMPLETENESS", "ACCURACY", "CONSISTENCY", "VALIDITY", "UNIQUENESS", "INTEGRITY"
getter/setter pair
eventPlugin → EventPlugin?
Subclasses can override this getter to be notified of changes to protobuf fields.
no setterinherited
hashCode → int
Calculates a hash code based on the contents of the protobuf.
no setterinherited
ignoreNull ↔ bool
Optional. Rows with null values will automatically fail a rule, unless ignore_null is true. In that case, such null rows are trivially considered passing.
getter/setter pair
info_ → BuilderInfo
no setteroverride
isFrozen → bool
Returns true if this message is marked read-only. Otherwise false.
no setterinherited
nonNullExpectation ↔ DataQualityRule_NonNullExpectation
ColumnMap rule which evaluates whether each column value is null.
getter/setter pair
rangeExpectation ↔ DataQualityRule_RangeExpectation
ColumnMap rule which evaluates whether each column value lies between a specified range.
getter/setter pair
regexExpectation ↔ DataQualityRule_RegexExpectation
ColumnMap rule which evaluates whether each column value matches a specified regex.
getter/setter pair
rowConditionExpectation ↔ DataQualityRule_RowConditionExpectation
Table rule which evaluates whether each row passes the specified condition.
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
setExpectation ↔ DataQualityRule_SetExpectation
ColumnMap rule which evaluates whether each column value is contained by a specified set.
getter/setter pair
statisticRangeExpectation ↔ DataQualityRule_StatisticRangeExpectation
ColumnAggregate rule which evaluates whether the column aggregate statistic lies between a specified range.
getter/setter pair
tableConditionExpectation ↔ DataQualityRule_TableConditionExpectation
Table rule which evaluates whether the provided expression is true.
getter/setter pair
threshold ↔ double
Optional. The minimum ratio of passing_rows / total_rows required to pass this rule, with a range of 0.0, 1.0.
getter/setter pair
uniquenessExpectation ↔ DataQualityRule_UniquenessExpectation
ColumnAggregate rule which evaluates whether the column has duplicates.
getter/setter pair
unknownFields → UnknownFieldSet
no setterinherited
