UCE Docs / DValue::get_by_path

Signature

DValue DValue::get_by_path(String path, String delim = "/") const

Parameters

path : delimited child path to traverse
delim : path separator string
return value : resolved child copy, or an empty DValue when traversal fails

Traverses nested map/list children without creating missing nodes. Empty path segments are ignored. If any segment is missing or an intermediate value is not map-shaped, the method returns an empty DValue.

Example

DValue cfg;
cfg["site"]["title"] = "UCE";
print(cfg.get_by_path("site/title").to_string(), "\n");
Output
