Package com.google.protobuf

Class UnknownFieldSet

java.lang.Object
com.google.protobuf.UnknownFieldSet
All Implemented Interfaces:
com.google.protobuf.MessageLite, com.google.protobuf.MessageLiteOrBuilder
public final class UnknownFieldSet extends Object implements com.google.protobuf.MessageLite
UnknownFieldSet keeps 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.

Every Message contains an UnknownFieldSet (and every Message.Builder contains a UnknownFieldSet.Builder).

Most users will never need to use this class.

      Get an empty UnknownFieldSet.

    • getDefaultInstanceForType

      public UnknownFieldSet getDefaultInstanceForType()

      public int getSerializedSize()
      Get the number of bytes required to encode this set.
      Specified by:
      getSerializedSize in interface com.google.protobuf.MessageLite

    • writeAsMessageSetTo

      Serializes the set and writes it to output using MessageSet wire format.
      Throws:
      IOException

    • getSerializedSizeAsMessageSet
