Description

你好:
如图,在我的workflow中存在类似于Z节点的存在,需要在Z中做switch case来确认到底走哪个流程(A1/B1/C1... ,N选一)。
请问,对于Z->A1/B1/C1这种switch-case,最佳实践是怎样的?
**当前我的做法是**
1. 对于Z:
ANYFLOW_INTERFACE(
ANYFLOW_EMIT_DATA(int, a)
ANYFLOW_EMIT_DATA(int, b)
ANYFLOW_EMIT_DATA(int, b)
)
2. 对于a1/b1/c1均有:
ANYFLOW_INTERFACE(
ANYFLOW_DEPEND_DATA(int, a/b/c)
)
3. 目前我在Z的process中是这么做的:通过cancel掉其他case的depend data实现。
```
switch ($value)
{
case $a_value:
*a.emit() = 1;
b.emit().cancel();
c.emit().cancel();
break;
case $b_value:
a.emit().cancel();
*b.emit() = 2;
c.emit().cancel();
break;
case $c_value:
a.emit().cancel();
b.emit().cancel();
*c.emit() = 3;
break;
}
```

Research direction
Start with the issue's Z-node process logic and the ANYFLOW_INTERFACE, ANYFLOW_EMIT_DATA, ANYFLOW_DEPEND_DATA, emit(), and cancel() usage shown in the example. Determine whether the existing cancellation approach is supported and what switch-case behavior should be recommended; done means a decided best-practice design or documented guidance for the N-way workflow branch.
