Shark工作流的实现和WMFC&OMG规范的对比
-----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。
