Methods

__construct

Constructor.

Parameters
Name	Description
data	array Optional. Data for populating the Message object.
↳ range_expectation	Google\Cloud\Dataplex\V1\DataQualityRule\RangeExpectation ColumnMap rule which evaluates whether each column value lies between a specified range.
↳ non_null_expectation	Google\Cloud\Dataplex\V1\DataQualityRule\NonNullExpectation ColumnMap rule which evaluates whether each column value is null.
↳ set_expectation	Google\Cloud\Dataplex\V1\DataQualityRule\SetExpectation ColumnMap rule which evaluates whether each column value is contained by a specified set.
↳ regex_expectation	Google\Cloud\Dataplex\V1\DataQualityRule\RegexExpectation ColumnMap rule which evaluates whether each column value matches a specified regex.
↳ uniqueness_expectation	Google\Cloud\Dataplex\V1\DataQualityRule\UniquenessExpectation ColumnAggregate rule which evaluates whether the column has duplicates.
↳ statistic_range_expectation	Google\Cloud\Dataplex\V1\DataQualityRule\StatisticRangeExpectation ColumnAggregate rule which evaluates whether the column aggregate statistic lies between a specified range.
↳ row_condition_expectation	Google\Cloud\Dataplex\V1\DataQualityRule\RowConditionExpectation Table rule which evaluates whether each row passes the specified condition.
↳ table_condition_expectation	Google\Cloud\Dataplex\V1\DataQualityRule\TableConditionExpectation Table rule which evaluates whether the provided expression is true.
↳ column	string Optional. The unnested column which this rule is evaluated against.
↳ ignore_null	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. Only applicable to ColumnMap rules.
↳ 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"]
↳ threshold	float Optional. The minimum ratio of passing_rows / total_rows required to pass this rule, with a range of [0.0, 1.0]. 0 indicates default value (i.e. 1.0).
