JbpmContext之源代码解读

1.JbpmContext作用
  处理流程的持久化操作，可以获得一系列Jbpm已经提供的服务。
2.JbpmContext使用

JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
 * try {
 *   TaskInstance taskInstance = ...
 *   
 *   ...do your process operations...
 *   
 *   // in case you update a process object that was not fetched
 *   // with a ...ForUpdate method, you have to save it.
 *   jbpmContext.save(processInstance);
 * finally {
 *   jbpmContext.close();
 * }

3.JbpmContext核心接口
 

public void deployProcessDefinition(ProcessDefinition processDefinition) {
    getGraphSession().deployProcessDefinition(processDefinition);
  }

 

public List getTaskList(String actorId) {
    return getTaskMgmtSession().findTaskInstances(actorId);
  }

 

public TaskInstance loadTaskInstance(long taskInstanceId) {
    return getTaskMgmtSession().loadTaskInstance(taskInstanceId);
  }

 
 

public ProcessInstance getProcessInstance(long processInstanceId) {
    return getGraphSession().getProcessInstance(processInstanceId);
  }

public ProcessInstance newProcessInstance(String processDefinitionName) {
    ProcessDefinition processDefinition = getGraphSession().findLatestProcessDefinition(processDefinitionName);
    return new ProcessInstance(processDefinition);
  }

public void save(ProcessInstance processInstance) {
    if (services!=null) {
      services.save(processInstance, this);
    }
  }

 

public void save(TaskInstance taskInstance) {
    save(taskInstance.getTaskMgmtInstance().getProcessInstance());
  }
