Re: [smila-user] SMILA: Pipelet outputs JSON

Hi Michalis,

 

If you could convert your JSONObject to “native” Objects (i.e. standard Java Maps, Arrays etc.) you’d be able to use the “objectToAny” Method of the AnyUtils (org.eclipse.smila.datamodel.util) directly.

 

Otherwise (if you only have the json String) you might use the IpcAnyReader’s method Any readJsonObject(final String json) to convert a JSON String to an Any (which of course can be a rather complex object containing AnyMaps and AnySeqs)…

(You can find IpcAnyReader in org.eclipse.smila.datamodel.ipc)

 

Bye,

Andreas

Betreff: [smila-user] SMILA: Pipelet outputs JSON

 

Hi all,

 

I have a rather easy (I guess) problem:

 

Until now, my pipelet was casting my computation results to Value objects and inserting them to the pipelet results, like this:

 

String output1 = “blah blah”;

Double output2 = 1.1;

 

Value outputValue1 = blackboard.getDataFactory().createStringValue(output);

blackboard.getMetadata(id).put("category", outputValue1);

 

Value outputValue2 = blackboard.getDataFactory().createDoubleValue(output2);

blackboard.getMetadata(id).put("score", outputValue2);

 

resultCollector.addResult(id);

 

 

 

Now, my output is a complex JSONObject casted to a String.

How do I add this to the pipelet results, not as String but as JSONObject?

Is it possible to have complex JSONObjects in the results? With complex I mean JSONObjects (and JSONArrays) inside of other JSONObjects (and JSONArrays).

If I add it as a String, it escapes all special characters (like / and “) and it looks like a mess.

It should be easy, since the pipelet output is already json.

 

Thanks,

 

Michalis
