Package com.google.protobuf
Class UnknownFieldSetLite
java.lang.Object
com.google.protobuf.UnknownFieldSetLite
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.
