Examples with TaskDataList org.kie.server.api.model.taskassigning.TaskDataList used on opensource projects

Example 1 with TaskDataList

use of org.kie.server.api.model.taskassigning.TaskDataList in project droolsjbpm-integration by kiegroup.

the class TaskDataReader method readTasks.

/**
 * Executes the {@link TaskAssigningRuntimeClient#findTasks(Long, List, LocalDateTime, Integer, Integer, TaskInputVariablesReadMode)}
 * method and return all the results. The paging reading is managed internally by this method.
 * <p>
 * @param fromTaskId filters the tasks with taskId >= fromTaskId. If null no filtering is applied.
 * @param status filters the tasks that are in one of the following status. If null or the empty list no filtering
 * is applied.
 * @param fromLastModificationDate filters the tasks with lastModificationDate >= fromLastModificationDate. If null
 * no filtering is applied.
 * @param pageSize sets the pageSize for the paged reading.
 * @param taskInputVariablesReadMode establishes the tasks input variables reading mode.
 * @return a list of TaskData with the jBPM tasks that met the filtering conditions. The potential owners of the task
 * is properly loaded with all the elements. The task inputs data is loaded accordingly with the selected taskInputVariablesReadMode.
 * @see TaskInputVariablesReadMode
