Interface CfnRuleset.RuleProperty

All Known Implementing Classes:

CfnRuleset.RuleProperty.Jsii$Proxy

Enclosing class:

CfnRuleset

public static interface CfnRuleset.RuleProperty

Represents a single data quality requirement that should be validated in the scope of this dataset.

Example:

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.databrew.*;
 RuleProperty ruleProperty = RuleProperty.builder()
         .checkExpression("checkExpression")

Method Detail

getCheckExpression

java.lang.String getCheckExpression()

The expression which includes column references, condition names followed by variable references, possibly grouped and combined with other conditions.

For example, (:col1 starts_with :prefix1 or :col1 starts_with :prefix2) and (:col1 ends_with :suffix1 or :col1 ends_with :suffix2) . Column and value references are substitution variables that should start with the ':' symbol. Depending on the context, substitution variables' values can be either an actual value or a column name. These values are defined in the SubstitutionMap. If a CheckExpression starts with a column reference, then ColumnSelectors in the rule should be null. If ColumnSelectors has been defined, then there should be no columnn reference in the left side of a condition, for example, is_between :val1 and :val2 .

getName

java.lang.String getName()

The name of the rule.

getColumnSelectors

default java.lang.Object getColumnSelectors()

List of column selectors.

Selectors can be used to select columns using a name or regular expression from the dataset. Rule will be applied to selected columns.

getDisabled

default java.lang.Object getDisabled()

A value that specifies whether the rule is disabled.

Once a rule is disabled, a profile job will not validate it during a job run. Default value is false.

getSubstitutionMap

default java.lang.Object getSubstitutionMap()

The map of substitution variable names to their values used in a check expression.

Variable names should start with a ':' (colon). Variable values can either be actual values or column names. To differentiate between the two, column names should be enclosed in backticks, for example, ":col1": "Column A".

getThreshold

default java.lang.Object getThreshold()

The threshold used with a non-aggregate check expression.

Non-aggregate check expressions will be applied to each row in a specific column, and the threshold will be used to determine whether the validation succeeds.

builder

static CfnRuleset.RuleProperty.Builder builder()

Returns:

a CfnRuleset.RuleProperty.Builder of CfnRuleset.RuleProperty
