As can be seen from the above execution:
Org.obe.Engine.WorkflowProcessInstance
Org.obe.Engine.WorkflowEngine
These two classes perform critical workflow part, which is the body part of the object of OBE. Org.obe.Engine.WorkflowProcessInstance includes:
1, StartProcess
2, StopProcess
3, ResumeProcess
4, PauseProcess
Wait
It can be seen that the main task in OBE is performed in WorkflowProcessInstance.
The main analysis below
Org.obe.Engine.WorkflowProcessInstance
Org.obe.Engine.WorkflowEngine
The implementation principle of two classes.
