Package com.ibm.streamsx.topology.json Description

JSON streams. JSON (JavaScript Object Notation) is a lightweight data-interchange format that can be used to exchange streams between applications implemented in different languages.

Java

Within Java the recommended stream type for JSON data is TStream<JSONObject>.
When a tuple is a JSON array the approach is to use an JSONObject with a single attribute payload containing the value (for example, an array of JSON objects}.

SPL

Within SPL the recommended stream type for JSON data is tuple<rstring jsonString>, representing serialized JSON. (see JSON). This is the convention used by the SPL toolkits com.ibm.streamsx.json and com.ibm.streamsx.inet.
