                                        String owner)

deleteTasksForExecution

public static void deleteTasksForExecution(ExecutionEntity executionEntity,
                                           Collection<TaskEntity> taskEntities,
                                           String deleteReason)

Deletes all tasks that relate to the same execution.

Parameters:

executionEntity - The ExecutionEntity to which the TaskEntity relate to.

taskEntities - Tasks to be deleted. It is assumed that all TaskEntity instances need to be related to the same execution.

deleteTask

public static void deleteTask(TaskEntity task,
                              String deleteReason,
                              boolean cascade,

                              boolean fireEvents)

Parameters:

task - The task to be deleted.

deleteReason - A delete reason that will be stored in the history tables.

cascade - If true, the historical counterpart will be deleted, otherwise it will be updated with an end time.

fireTaskListener - If true, the delete event of the task listener will be called.

fireEvents - If true, the event dispatcher will be used to fire an event for the deletion.
