It accepts a boolean `newBoolean` parameter: `true` signifies an output, and `false` signifies no output. An optional `opt_check` parameter specifies the returned type or a list of types, allowing for type validation. If `opt_check` is null or undefined, any type can be returned. The method returns void.\n"]]
