For the JSON output of Get DataNode we need to alter the DataMapUtils class. The function toDataMap translates a datanode object to a JSON output:
public static Map<String, Object> toDataMap(final DataNode dataNode) {
final boolean isTopLevelNode = dataNode.getXpath().lastIndexOf('/') == 0;
if (isTopLevelNode) {
String containerName = dataNode.getXpath().substring(1);
return ImmutableMap.<String, Object>builder().put(containerName,
ImmutableMap.<String, Object>builder()
.putAll(dataNode.getLeaves())
.putAll(listElementsAsMap(dataNode.getChildDataNodes()))
.putAll(containerElementsAsMap(dataNode.getChildDataNodes()))
.build()
).build();
} else {
return ImmutableMap.<String, Object>builder()
.putAll(dataNode.getLeaves())
.putAll(listElementsAsMap(dataNode.getChildDataNodes()))
.putAll(containerElementsAsMap(dataNode.getChildDataNodes()))
.build();
}
}
We only want the container name on the top level of the JSON output and as such have to distinguish between a top level node and non top level node. We create an outer map to wrap the inner map which creates the appropriate levels in the JSON output.
