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.

Method Details

newBuilder

public static UnknownFieldSet.Builder newBuilder()

Create a new UnknownFieldSet.Builder.

newBuilder

public static UnknownFieldSet.Builder newBuilder(UnknownFieldSet copyFrom)

Create a new UnknownFieldSet.Builder and initialize it to be a copy of copyFrom.

getDefaultInstance

public static UnknownFieldSet getDefaultInstance()

Get an empty UnknownFieldSet.

getDefaultInstanceForType

public UnknownFieldSet getDefaultInstanceForType()

Specified by:

getDefaultInstanceForType in interface com.google.protobuf.MessageLiteOrBuilder

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

isEmpty

public boolean isEmpty()

Whether the field set has no fields.

asMap

public Map<Integer,UnknownFieldSet.Field> asMap()

Get a map of fields in the set by number.

hasField

public boolean hasField(int number)

Check if the given field number is present in the set.

getField

public UnknownFieldSet.Field getField(int number)

Get a field by number. Returns an empty field if not present. Never returns null.

writeTo

Serializes the set and writes it to output.

Specified by:

writeTo in interface com.google.protobuf.MessageLite
