Looking at the MessageContext object in my Java callout, and I see that the MessageContext interface specifies a `ctx.setVariable(String,Object)` method. I am curious how non-string objects are handled as flow variables.
For instance, if I have the following code:
JSONObject fooObject = doSomeWork();
messageContext.setVariable("foo",fooObject);I see that this is allowed by the interface ... how is this flattened to be accessible by downstream policies?
My hope is that in future policies I could access the variable in a json-path-ish way as such:
{foo.the[2].path}Alternatively, is it better to iterate through the object and flatten it into strings myself before persisting it to the messageContext to ensure that downstream policies can reference that data?
