    • mergeIn

      public JsonObject mergeIn(JsonObject other)

      This is the equivalent of putting all the entries of the other JSON object into this object. This is not a deep merge, entries containing (sub) JSON objects will be replaced entirely.

    • mergeInDeep

      public JsonObject mergeInDeep(JsonObject other)
      Merges in another JSON object. A deep merge (recursive) matches (sub) JSON objects in the existing tree and replaces all matching entries. JsonArrays are treated like any other entry, i.e. replaced entirely.

    • mergeIn

      public JsonObject mergeIn(JsonObject other, int depth)
      Merges in another JSON object. The merge is deep (recursive) to the specified level. If depth is 0, no merge is performed, if depth is greater than the depth of one of the objects, a full deep merge is performed.
