## Class UnknownFieldSetLite

- java.lang.Object
- - com.google.protobuf.UnknownFieldSetLite

-     public final class UnknownFieldSetLite
      extends java.lang.Object

  `UnknownFieldSetLite` is 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 compiled before the new types were added.

  For use by generated code only.
