Class UnknownFieldSet

public sealed class UnknownFieldSet : object

Used to keep track of fields which were seen when parsing a protocol message but whose field numbers or types are unrecognized. This most frequently occurs when new fields are added to a message type and then messages containing those fields are read by old software that was built before the new types were added.

Most users will never need to use this class directly.
