the class GeneralTopologyContextImpl method getOutputToComponentsFields.

public static Map<String, Map<String, Fields>> getOutputToComponentsFields(List<TopologyAPI.OutputStream> outputs) {
    Map<String, Map<String, Fields>> outputFields = new HashMap<>();
    for (TopologyAPI.OutputStream outputStream : outputs) {
        String componentName = outputStream.getStream().getComponentName();
        String streamId = outputStream.getStream().getId();
        Map<String, Fields> componentFields = outputFields.get(componentName);
        if (componentFields == null) {
            componentFields = new HashMap<>();
        }
        // Get the fields of a particular OutputStream
        List<String> retval = new ArrayList<>();
        for (TopologyAPI.StreamSchema.KeyType kt : outputStream.getSchema().getKeysList()) {
            retval.add(kt.getKey());
        }
        // Put it into the map
        componentFields.put(streamId, new Fields(retval));
        outputFields.put(componentName, componentFields);
    }
    return outputFields;
}
