Method Detail

aggregateSingleVariable

public Object aggregateSingleVariable(DelegatePlanItemInstance planItemInstance,
                                      PlanItemVariableAggregatorContext context)

Description copied from interface: PlanItemVariableAggregator

Create a single variable value based on the provided aggregation definition. This is called after a single repeatable plan item instance is completed, or an overview for a non completed repeatable plan item instance is needed.

Specified by:

aggregateSingleVariable in interface PlanItemVariableAggregator

Parameters:

planItemInstance - the delegate planItemInstance from where we need to get data from

context - the aggregation context

Returns:

the value for the aggregated variable

aggregateMultiVariables

public Object aggregateMultiVariables(DelegatePlanItemInstance planItemInstance,
                                      List<? extends VariableInstance> instances,
                                      PlanItemVariableAggregatorContext context)

Description copied from interface: PlanItemVariableAggregator

Aggregated the provided variable instances into one variable value. This is called when all repeatable plan item instances are complete, or an overview for repeatable plan item instances is needed.

Specified by:

aggregateMultiVariables in interface PlanItemVariableAggregator

Parameters:

planItemInstance - the delegated planItemInstance for which we need to do the aggregation

instances - the variable values that should be aggregated (these variables are created based on the value from PlanItemVariableAggregator.aggregateSingleVariable(DelegatePlanItemInstance, PlanItemVariableAggregatorContext))

context - the aggregation context

Returns:

the aggregated value
