Stay organized with collections

public abstract class GeneratedMessageV3 extends AbstractMessage implements Serializable
All generated protocol message classes extend this class. This class
implements most of the Message and Builder interfaces using Java reflection.
Users can ignore this class and pretend that generated messages implement
the Message interface directly.
Static Fields
alwaysUseFieldBuilders
protected static boolean alwaysUseFieldBuilders
For testing. Allows a test to disable the optimization that avoids using field builders for
nested messages until they are requested. By disabling this optimization, existing tests can be
reused to test the field builders.

Methods
getAllFields()
public Map<Descriptors . FieldDescriptor , Object > getAllFields ()
getDescriptorForType()
public Descriptors . Descriptor getDescriptorForType ()
getField(Descriptors.FieldDescriptor field)
public Object getField ( Descriptors . FieldDescriptor field )
Returns
Type
Description
Object
getOneofFieldDescriptor(Descriptors.OneofDescriptor oneof)
public Descriptors . FieldDescriptor getOneofFieldDescriptor ( Descriptors . OneofDescriptor oneof )
TODO(jieluo): Clear it when all subclasses have implemented this method.
Overrides
getParserForType()
public Parser <? extends GeneratedMessageV3 > getParserForType ()
Returns
Type
Description
Parser <? extends com.google.protobuf.GeneratedMessageV3 >
getRepeatedField(Descriptors.FieldDescriptor field, int index)
public Object getRepeatedField ( Descriptors . FieldDescriptor field , int index )
Returns
Type
Description
Object
getRepeatedFieldCount(Descriptors.FieldDescriptor field)
public int getRepeatedFieldCount ( Descriptors . FieldDescriptor field )
Returns
Type
Description
int
getSerializedSize()
public int getSerializedSize ()
Get the number of bytes required to encode this message. The result is only computed on the
first call and memoized after that.
If this message requires more than Integer.MAX_VALUE bytes to encode, the return value will
be smaller than the actual number of bytes required and might be negative.
Returns
Type
Description
int
Overrides
getUnknownFields()
public UnknownFieldSet getUnknownFields ()
hasField(Descriptors.FieldDescriptor field)
public boolean hasField ( Descriptors . FieldDescriptor field )
hasOneof(Descriptors.OneofDescriptor oneof)
public boolean hasOneof ( Descriptors . OneofDescriptor oneof )
TODO(jieluo): Clear it when all subclasses have implemented this method.
Overrides
internalGetFieldAccessorTable()
protected abstract GeneratedMessageV3 . FieldAccessorTable internalGetFieldAccessorTable ()
Get the FieldAccessorTable for this type. We can't have the message
class pass this in to the constructor because of bootstrapping trouble
with DescriptorProtos.
internalGetMapField(int fieldNumber)
protected MapField internalGetMapField ( int fieldNumber )
Gets the map field with the given field number. This method should be overridden in the
generated message class if the message contains map fields.
Unlike other field types, reflection support for map fields can't be implemented based on
generated public API because we need to access a map field as a list in reflection API but the
generated API only allows us to access it as a map. This method returns the underlying map
field directly and thus enables us to access the map field as a list.
Parameter
Name
Description
fieldNumber
int
isInitialized()
public boolean isInitialized ()
Overrides
makeExtensionsImmutable()
protected void makeExtensionsImmutable ()
Used by parsing constructors in generated classes.
protected void mergeFromAndMakeImmutableInternal ( CodedInputStream input , ExtensionRegistryLite extensionRegistry )
newBuilderForType(AbstractMessage.BuilderParent parent)
protected Message . Builder newBuilderForType ( AbstractMessage . BuilderParent parent )
Overrides
newBuilderForType(GeneratedMessageV3.BuilderParent parent)
protected abstract Message . Builder newBuilderForType ( GeneratedMessageV3 . BuilderParent parent )
TODO(xiaofeng): remove this together with GeneratedMessageV3.BuilderParent.
newInstance(GeneratedMessageV3.UnusedPrivateParameter unused)
protected Object newInstance ( GeneratedMessageV3 . UnusedPrivateParameter unused )
Creates a new instance of this message type. Overridden in the generated code.
Returns
Type
Description
Object
protected boolean parseUnknownField ( CodedInputStream input , UnknownFieldSet . Builder unknownFields , ExtensionRegistryLite extensionRegistry , int tag )
Called by subclasses to parse an unknown field.
Returns
Type
Description
boolean
true
unless the tag is an end-group tag.
protected boolean parseUnknownFieldProto3 ( CodedInputStream input , UnknownFieldSet . Builder unknownFields , ExtensionRegistryLite extensionRegistry , int tag )
Delegates to parseUnknownField. This method is obsolete, but we must retain it for
compatibility with older generated code.
writeReplace()
protected Object writeReplace ()
Replaces this object in the output stream with a serialized form.
Part of Java's serialization magic. Generated sub-classes must override
this method by calling return super.writeReplace();
Returns
Type
Description
Object
a SerializedForm of this message
writeTo(CodedOutputStream output)
public void writeTo ( CodedOutputStream output )
Serializes the message and writes it to output
. This does not flush or close the
stream.
Overrides
