public List<String> getExternalDocs() {
        return externalDocs;
    }
Adds or replaces the JSON value in the generated OpenAPI document
at the given JSON pointer locations with a different JSON value.

<p>The value must be a map where each key is a valid JSON pointer
string as defined in RFC 6901. Each value in the map is the JSON
value to add or replace at the given target.

<p>Values are added using similar semantics of the "add" operation
of JSON Patch, as specified in RFC 6902, with the exception that
adding properties to an undefined object will create nested
objects in the result as needed.

@param jsonAdd Map of JSON path to values to patch in.
