红帽全球峰会4.7. BPMN2 在进程设计器中连接对象
连接对象会在两个 BPMN2 元素之间创建一个关联。当连接对象被定向时，关联是连续的，这表示其中一个元素在进程的实例内立即执行。连接对象可以在所关联的进程元素的顶部、右或左边启动和结束。OMG BPMN2 规范允许您使用您的自由，将连接对象放在使流程行为易于理解和遵循的方式中。
BPMN2 支持两种类型的连接对象：
- 序列流：连接进程的元素并定义实例内执行这些元素的顺序。
- 关联流：在没有执行语义的情况下连接进程的元素。关联流可以是不直接的，也可以是单向。
注意
新进程设计器只支持未直接关联流程。旧设计器支持了一个方向和一致性流程。
