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.
