如何在WSO2 CEP的Siddhi扩展自定义函数中按名称获取参数？

Question

When I pass params into my Custom Function and I want to get it, I need to do it by that:

 @Override
    protected Object process(Object obj) {

param1 = obj[0];
param2 = obj[1];
}

but when I have 30 params I need to repeat this process almost 30 times, and when something change in my input params I will have to change index too. So my question is, is possible to get params in Custom Fucntion by they names? Like that for example:

param1 = "getAttributeByName('param1Name')";
param2 = "getAttributeByName('param2Name')";

Similar thing is available in Transformer, but is it possible in Function?

没有Kacu，这是不可能的。.但是由于您具有流定义，因此您无法从中获取事件模式信息并按索引获取属性。
