Class StandardDataQueryAggregationValidator

java.lang.Object

com.flowable.indexing.query.builder.standard.StandardDataQueryAggregationValidator

All Implemented Interfaces:

QueryDefinitionValidator

public class StandardDataQueryAggregationValidator
extends Object
implements QueryDefinitionValidator

Validates that aggregations in a QueryDefinitionModel's StandardDataQueryConfiguration have all required properties set for their type:

• Direct-field aggregations (sumFieldValue, avgFieldValue, maxFieldValue, minFieldValue, groupByField) require a non-empty fieldName.
• Nested-field aggregations (groupByNestedField) require both fieldName and nestedPath.
• Variable-based aggregations (sumVariableValue, avgVariableValue, maxVariableValue, minVariableValue, stddevVariableValue, distributionVariableValue) require a non-empty variableName.

Silently passes for query definitions that don't use the query-builder subtype (template queries, legacy queries), since those don't have a StandardDataQueryConfiguration.
