      aggregation - the aggregation definition
      cmmnEngineConfiguration - the cmmn engine configuration
      Returns:
      the created variables (not yet saved), or null if no name could be resolved for the variable

    • aggregate

      public static VariableInstanceEntity aggregate(DelegatePlanItemInstance planItemInstance, PlanItemVariableAggregatorContext aggregationContext, CmmnEngineConfiguration cmmnEngineConfiguration)
      Create an aggregated variable instance for the given aggregation context.
      Parameters:
      planItemInstance - the planItemInstance
      aggregationContext - the aggregation context
      cmmnEngineConfiguration - the cmmn engine configuration
      Returns:
      the created variables (not yet saved), or null if no name could be resolved for the variable

    • aggregate

      public static VariableInstanceEntity aggregate(DelegatePlanItemInstance planItemInstance, PlanItemVariableAggregatorContext aggregationContext, CmmnEngineConfiguration cmmnEngineConfiguration, PlanItemVariableAggregator aggregator, String targetVarName)
      Parameters:
