Method Details

isJsonPathTemplate

protected static boolean isJsonPathTemplate(String argument)

toJsonPathTemplate

protected static String toJsonPathTemplate(List<Object> pathElements,
 int to,
 boolean quotePathElements)

Introduce JSON path template as optional first parameter If first parameter is a literal string, interpret it as JSON path. The remaining arguments are interpreted as varargs named parameters that are used as positional parameters for the json path template. For postgres we need to parse the json path template and reformulate it to the postgres syntax.
