Example 10 with Pool

use of org.activiti.bpmn.model.Pool in project Activiti by Activiti.

the class ParticipantParser method parse.

public void parse(XMLStreamReader xtr, BpmnModel model) throws Exception {
    if (StringUtils.isNotEmpty(xtr.getAttributeValue(null, ATTRIBUTE_ID))) {
        Pool pool = new Pool();
        pool.setId(xtr.getAttributeValue(null, ATTRIBUTE_ID));
        pool.setName(xtr.getAttributeValue(null, ATTRIBUTE_NAME));
        pool.setProcessRef(xtr.getAttributeValue(null, ATTRIBUTE_PROCESS_REF));
