SPL函数可以调用Submit（）吗？

Question

I'm trying to call submit() from an SPL function (that is called from a Custom operator), but it is not working. It complains about the name of my stream:

submit({prop1=value1, prop2=value2}, MyStream);

ERROR: An unknown identifier was referenced in the SPL program: MyStream

Is this supported?

Answer 1

No, this is not supported. submit() can only be called inside the Custom operator, within its onTuple , onPunct , or onProcess clauses. It cannot be called from an SPL function.
