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.

Field Details

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.

unknownFields

protected UnknownFieldSet unknownFields

For use by generated code only.

TODO: mark this private and final (breaking change)

Method Details

getParserForType

public Parser<? extends GeneratedMessage> getParserForType()

TODO: Remove this unnecessary intermediate implementation of this method.

Specified by:

getParserForType in interface Message

Specified by:

getParserForType in interface MessageLite

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.

getDescriptorForType

public Descriptors.Descriptor getDescriptorForType()

Description copied from interface: MessageOrBuilder

Get the message's type's descriptor. This differs from the getDescriptor() method of generated message classes in that this method is an abstract method of the Message interface whereas getDescriptor() is a static method of a specific class. They return the same thing.

Specified by:

getDescriptorForType in interface MessageOrBuilder

mergeFromAndMakeImmutableInternal

@Deprecated
protected void mergeFromAndMakeImmutableInternal(CodedInputStream input,
 ExtensionRegistryLite extensionRegistry)
                                          throws InvalidProtocolBufferException

Deprecated.

use newBuilder().mergeFrom() instead

TODO: This method should be removed. It enables parsing directly into an "immutable" message. Have to leave it for now to support old gencode.

Throws:

InvalidProtocolBufferException

isInitialized

public boolean isInitialized()

Description copied from interface: MessageLiteOrBuilder

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

See also: MessageOrBuilder.getInitializationErrorString()

Specified by:

isInitialized in interface MessageLiteOrBuilder

Overrides:

isInitialized in class AbstractMessage

getAllFields

public Map<Descriptors.FieldDescriptor,Object> getAllFields()

Description copied from interface: MessageOrBuilder

Returns a collection of all the fields in this message which are set and their corresponding values. A singular ("required" or "optional") field is set iff hasField() returns true for that field. A "repeated" field is set iff getRepeatedFieldCount() is greater than zero. The values are exactly what would be returned by calling MessageOrBuilder.getField(Descriptors.FieldDescriptor) for each field. The map is guaranteed to be a sorted map, so iterating over it will return fields in order by field number.
If this is for a builder, the returned map may or may not reflect future changes to the builder. Either way, the returned map is itself unmodifiable.

Specified by:

getAllFields in interface MessageOrBuilder

hasOneof

public boolean hasOneof(Descriptors.OneofDescriptor oneof)

Description copied from interface: MessageOrBuilder

Returns true if the given oneof is set.

Specified by:

hasOneof in interface MessageOrBuilder

Overrides:

hasOneof in class AbstractMessage

getOneofFieldDescriptor

public Descriptors.FieldDescriptor getOneofFieldDescriptor(Descriptors.OneofDescriptor oneof)

Description copied from interface: MessageOrBuilder

Obtains the FieldDescriptor if the given oneof is set. Returns null if no field is set.

Specified by:

getOneofFieldDescriptor in interface MessageOrBuilder

Overrides:

getOneofFieldDescriptor in class AbstractMessage

hasField

public boolean hasField(Descriptors.FieldDescriptor field)

Description copied from interface: MessageOrBuilder

Returns true if the given field is set. This is exactly equivalent to calling the generated "has" accessor method corresponding to the field. The return value of hasField() is semantically meaningful only for fields where field.hasPresence() == true.

Specified by:

hasField in interface MessageOrBuilder

getField

public Object getField(Descriptors.FieldDescriptor field)

Description copied from interface: MessageOrBuilder

Obtains the value of the given field, or the default value if it is not set. For primitive fields, the boxed primitive value is returned. For enum fields, the EnumValueDescriptor for the value is returned. For embedded message fields, the sub-message is returned. For repeated fields, a java.util.List is returned.

Specified by:

getField in interface MessageOrBuilder

getRepeatedFieldCount

public int getRepeatedFieldCount(Descriptors.FieldDescriptor field)

Description copied from interface: MessageOrBuilder

Gets the number of elements of a repeated field. This is exactly equivalent to calling the generated "Count" accessor method corresponding to the field.

Specified by:

getRepeatedFieldCount in interface MessageOrBuilder

getRepeatedField

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

Description copied from interface: MessageOrBuilder

Gets an element of a repeated field. For primitive fields, the boxed primitive value is returned. For enum fields, the EnumValueDescriptor for the value is returned. For embedded message fields, the sub-message is returned.

Specified by:

getRepeatedField in interface MessageOrBuilder

getUnknownFields

public UnknownFieldSet getUnknownFields()

Description copied from interface: MessageOrBuilder

Get the UnknownFieldSet for this message.

Specified by:

getUnknownFields in interface MessageOrBuilder

parseUnknownField

protected boolean parseUnknownField(CodedInputStream input,
 UnknownFieldSet.Builder unknownFields,
 ExtensionRegistryLite extensionRegistry,
 int tag)
                             throws IOException

Called by subclasses to parse an unknown field.

TODO remove this method

Returns:

true unless the tag is an end-group tag.

 UnknownFieldSet.Builder unknownFields,
 ExtensionRegistryLite extensionRegistry,
 int tag)
                                   throws IOException

Delegates to parseUnknownField. This method is obsolete, but we must retain it for compatibility with older generated code.

TODO remove this method

Throws:

IOException

parseWithIOException

protected static <M extends Message> M parseWithIOException(Parser<M> parser,

writeTo

public void writeTo(CodedOutputStream output)
             throws IOException

Description copied from interface: MessageLite

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

Specified by:

writeTo in interface MessageLite

Overrides:

writeTo in class AbstractMessage

Throws:

IOException

getSerializedSize

public int getSerializedSize()

Description copied from interface: MessageLite

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.

Specified by:

getSerializedSize in interface MessageLite

Overrides:

getSerializedSize in class AbstractMessage

newInstance

protected Object newInstance(GeneratedMessage.UnusedPrivateParameter unused)

Creates a new instance of this message type. Overridden in the generated code.

newMessageScopedGeneratedExtension

public static <ContainingT extends Message,
T>
GeneratedMessage.GeneratedExtension<ContainingT,T> newMessageScopedGeneratedExtension(Message scope,
 int descriptorIndex,
 Class<?> singularType,
 Message defaultInstance)

For use by generated code only.

newFileScopedGeneratedExtension

public static <ContainingT extends Message,
T>
GeneratedMessage.GeneratedExtension<ContainingT,T> newFileScopedGeneratedExtension(Class<?> singularType,
 Message defaultInstance)

For use by generated code only.

internalGetMapFieldReflection

protected MapFieldReflectionAccessor internalGetMapFieldReflection(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.

internalGetMapField

@Deprecated
protected MapField internalGetMapField(int fieldNumber)

Deprecated.

TODO: Remove, exists for compatibility with generated code.

writeReplace

protected Object writeReplace()
                       throws ObjectStreamException

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:

a SerializedForm of this message

Throws:

ObjectStreamException

isStringEmpty
