                                           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 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.
