Example 1 with ProcessInstanceQueryImpl

use of org.activiti.engine.impl.ProcessInstanceQueryImpl in project Activiti by Activiti.

the class ExecutionEntityManager method deleteProcessInstanceCascade.

private void deleteProcessInstanceCascade(ExecutionEntity execution, String deleteReason, boolean deleteHistory) {
    CommandContext commandContext = Context.getCommandContext();
    ProcessInstanceQueryImpl processInstanceQuery = new ProcessInstanceQueryImpl(commandContext);

    for (ProcessInstance subProcess : subProcesses) {
        deleteProcessInstanceCascade((ExecutionEntity) subProcess, deleteReason, deleteHistory);
    }
    commandContext.getTaskEntityManager().deleteTasksByProcessInstanceId(execution.getId(), deleteReason, deleteHistory);

    }
    // delete the execution BEFORE we delete the history, otherwise we will produce orphan HistoricVariableInstance instances
    execution.deleteCascade(deleteReason);
