fun merge(at: DatasyncTime = DatasyncTime.Now, value: Any?, callback: WebcomDoneCallback? = null): Unit
Merges some data with the data at this data node asynchronously.
The requested merge operation is done asynchronously in the same way than the set method depending on the chosen policy.
The value to merge may be of any kind. It is first serialized to a tree-like representation supported by the Webcom database, and then the resulting 1st-level keys are merged with the ones existing at the current data node. Keys from the value to merge overwrite keys with the same name in the current data. Keys from the current data that don't occur in the value to merge are kept as is.
