Method Detail

calculateRemovalTime

public Date calculateRemovalTime(HistoricProcessInstanceEventEntity historicRootProcessInstance,
                                 ProcessDefinition processDefinition)

Description copied from interface: HistoryRemovalTimeProvider

Calculates the removal time of historic entities related to processes. START: the removal time is set for each historic entity separately on occurrence (creation). HistoricScopeInstanceEvent.getEndTime() is null END: the removal time is updated simultaneously for all historic entities which belong to the root process instance when it ends. HistoricScopeInstanceEvent.getEndTime() is not null

Specified by:

calculateRemovalTime in interface HistoryRemovalTimeProvider

Parameters:

historicRootProcessInstance - which is either in state running or ended

processDefinition - of the historic root process instance

Returns:

the removal time for historic process instances

public Date calculateRemovalTime(HistoricDecisionInstanceEntity historicRootDecisionInstance,
                                 DecisionDefinition decisionDefinition)

Description copied from interface: HistoryRemovalTimeProvider

Calculates the removal time of historic entities related to decisions.

Specified by:

calculateRemovalTime in interface HistoryRemovalTimeProvider

decisionDefinition - of the historic root decision instance

Returns:

the removal time for historic decision instances
