Class JsonNodeBuilder

java.lang.Object

org.apache.jackrabbit.oak.json.JsonNodeBuilder

public class JsonNodeBuilder
extends Object

A utility class to persist a configuration that is in the form of JSON into the node store.

This is used to persist a small set of configuration nodes, eg. index definitions, using a simple JSON format.

The node type does not need to be set on a per-node basis. Where it is missing, the provided node type is used (e.g. "nt:unstructured")

A "jcr:uuid" is automatically added for nodes of type "nt:resource".

String, string arrays, boolean, blob, long, and double values are supported. Values that start with ":blobId:...base64..." are stored as binaries. "str:", "nam:" and "dat:" prefixes are removed.

"null" entries are not supported.
