請按任意鍵繼續 . . .

從上面的執行可以看出：

org.obe.engine.WorkflowProcessInstance

org.obe.engine.WorkflowEngine

這兩個類執行了關鍵的工作流程部分，是obe具體執行的主體部分。
org.obe.engine.WorkflowProcessInstance 中主要的方法包括：

1、  startProcess

2、  stopProcess

3、  resumeProcess

4、  pauseProcess

等

可見，obe中主要的工作是在WorkflowProcessInstance中執行的。

下文主要分析

org.obe.engine.WorkflowProcessInstance

org.obe.engine.WorkflowEngine

兩個類的執行原理。

待續
