Class GeneratedMessage (3.19.4)

public abstract class GeneratedMessage 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.

Field Value

`boolean`

Static Methods

<ContainingType,Type>newFileScopedGeneratedExtension(Class singularType, Message defaultInstance)

public static GeneratedMessage.GeneratedExtension<ContainingType,Type> <ContainingType,Type>newFileScopedGeneratedExtension(Class singularType, Message defaultInstance)

For use by generated code only.

Parameters
Name	Description
`singularType`	`Class`
`defaultInstance`	`Message`

Returns
Type	Description
`GeneratedExtension<ContainingType,Type>`

<ContainingType,Type>newFileScopedGeneratedExtension(Class singularType, Message defaultInstance, String descriptorOuterClass, String extensionName)

public static GeneratedMessage.GeneratedExtension<ContainingType,Type> <ContainingType,Type>newFileScopedGeneratedExtension(Class singularType, Message defaultInstance, String descriptorOuterClass, String extensionName)

Used in proto1 generated code only.

After enabling bridge, we can define proto2 extensions (the extended type is a proto2 mutable message) in a proto1 .proto file. For these extensions we should generate proto2 GeneratedExtensions.

Returns
Type	Description
`GeneratedExtension<ContainingType,Type>`

Parameter
Name	Description
`field`	`Descriptors.FieldDescriptor`

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.

Parameter
Name	Description
`oneof`	`Descriptors.OneofDescriptor`

Returns
Type	Description
`Descriptors.FieldDescriptor`

Overrides

AbstractMessage.getOneofFieldDescriptor(Descriptors.OneofDescriptor oneof)

getParserForType()

public Parser<? extends GeneratedMessage> getParserForType()

Returns
Type	Description
`Parser<? extends com.google.protobuf.GeneratedMessage>`

getRepeatedField(Descriptors.FieldDescriptor field, int index)

public Object getRepeatedField(Descriptors.FieldDescriptor field, int index)

Parameters
Name	Description
`field`	`Descriptors.FieldDescriptor`
`index`	`int`

Returns
Type	Description
`Object`

getRepeatedFieldCount(Descriptors.FieldDescriptor field)

public int getRepeatedFieldCount(Descriptors.FieldDescriptor field)

Parameter
Name	Description
`field`	`Descriptors.FieldDescriptor`

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

AbstractMessage.getSerializedSize()

getUnknownFields()

public UnknownFieldSet getUnknownFields()

Returns
Type	Description
`UnknownFieldSet`

hasField(Descriptors.FieldDescriptor field)

public boolean hasField(Descriptors.FieldDescriptor field)

Parameter
Name	Description
`field`	`Descriptors.FieldDescriptor`

Returns
Type	Description
`boolean`

hasOneof(Descriptors.OneofDescriptor oneof)

public boolean hasOneof(Descriptors.OneofDescriptor oneof)

TODO(jieluo): Clear it when all subclasses have implemented this method.

Parameter
Name	Description
`oneof`	`Descriptors.OneofDescriptor`

Returns
Type	Description
`boolean`

Overrides

AbstractMessage.hasOneof(Descriptors.OneofDescriptor oneof)

internalGetFieldAccessorTable()

protected abstract GeneratedMessage.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.

Returns
Type	Description
`GeneratedMessage.FieldAccessorTable`

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`

Returns
Type	Description
`MapField`

isInitialized()

public boolean isInitialized()

Returns true if all required fields in the message and all embedded messages are set, false otherwise.

Returns
Type	Description
`boolean`

Overrides

AbstractMessage.isInitialized()

makeExtensionsImmutable()

protected void makeExtensionsImmutable()

Used by parsing constructors in generated classes.

Create a nested builder.

Parameter
Name	Description

Returns
Type	Description

AbstractMessage.newBuilderForType(AbstractMessage.BuilderParent parent)

TODO(xiaofeng): remove this together with GeneratedMessage.BuilderParent.

Parameter
Name	Description

Exceptions
Type	Description
`IOException`

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

Exceptions
Type	Description
`ObjectStreamException`

writeTo(CodedOutputStream output)

public void writeTo(CodedOutputStream output)

Serializes the message and writes it to output. This does not flush or close the stream.
