-----第十部分：分析obe自带例子引擎的执行过程
关键字：Shark 工作流 WMFC OMG 规范
下面工作流执行的过程参见：-----第五部分：工作流流程的设计
下面是采用obe引擎执行第五部分定义的“辞职申请”的过程的日志。

请按任意键继续 . . .
从上面的执行可以看出：
org.obe.engine.WorkflowProcessInstance
org.obe.engine.WorkflowEngine
这两个类执行了关键的工作流程部分，是obe具体执行的主体部分。
org.obe.engine.WorkflowProcessInstance 中主要的方法包括：
1、 startProcess
2、 stopProcess
3、 resumeProcess
4、 pauseProcess
等
可见，obe中主要的工作是在WorkflowProcessInstance中执行的。
下文主要分析
org.obe.engine.WorkflowProcessInstance
org.obe.engine.WorkflowEngine
两个类的执行原理。
