This is the first developer document of the PE system. First, let's give a brief introduction to the PE! PE is a WF-based process engine for developers. It is still very small and has limited functions. Please forgive me. Currently, the PE version is 0.1, so please do not try to use it in commercial projects. The consequences are not complicated. Pai_^ the main task that PE can accomplish in the current version is to construct a process and run it. Although some of the functions can be released,
-based programming model, I think this is meaningless. Isn't it a visual process design environment and execution engine? However, it is certain that the author adds a stable choice to the open-source community.
Jbpm 4/PVMCurrently, it is still under development and the design is relatively mature. At least the APIS design that is exposed to the customer code is reasonable. Unfortunately, PVM is not as good as the author and JBoss, so feasible (fully compatible with BPEL) that only the author h

different. Therefore, it is concluded that there can be only one ProcessInstance in a process, and multiple Execution instances can exist.
Task)
Tasks are the Task information generated when a process is executed in a certain step or stage.
In the previous article, we will introduce how to draw a flowchart and how to deploy the process definition. The relationship between the process definition and the process instance has just been introduced. Now we should start the process instance:

1. Theoretical Model
This mode is called implicit termination or natural termination. That is, when no successor node exists for all running nodes, the process is deemed to have ended.
2. Application
This mode is now supported by the standards of the process such as BPEL, xpdl, and BPMN, that is, the end node does not need to be specified, as long as all nodes are run (or no successor node is found ), the process ends.
It is interesting that the P

Unlike JBPM, Activiti is not a level (I think these two frameworks are chatty), Snaker is a lite version (because some features are discarded, especially for BPMN support).
