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 should generally ignore this class and use the Message interface instead.

This class is intended to only be extended by protoc created gencode. It is not intended or supported to extend this class, and any protected methods may be removed without it being considered a breaking change as long as all supported gencode does not depend on the changed methods.

TODO: Stop using SingleFieldBuilder and remove this setting

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

getAllFieldsMutable

private Map<Descriptors.FieldDescriptor, Object> getAllFieldsMutable(boolean getBytesForString)

Internal helper to return a modifiable map containing all the fields. The returned Map is modifiable so that the caller can add additional extension fields to implement getAllFields().

Parameters:

getBytesForString - whether to generate ByteString for string fields

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

getAllFieldsRaw

Map<Descriptors.FieldDescriptor, Object> getAllFieldsRaw()

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 getFieldRaw(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.

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

getFieldRaw

Object getFieldRaw(Descriptors.FieldDescriptor field)

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. For present string fields, a ByteString is returned representing the bytes that the field contains.

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

Get the UnknownFieldSet for this message.

Specified by:

getUnknownFields in interface MessageOrBuilder

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,

 Message defaultInstance)

For use by generated code only.

getMethodOrDie

private static Method getMethodOrDie(Class<?> clazz,
 String name,
 Class<?>... params)

Calls Class.getMethod and throws a RuntimeException if it fails.

invokeOrDie

@CanIgnoreReturnValue
private static Object invokeOrDie(Method method,
 Object object,
 Object... params)

Calls invoke and throws a RuntimeException if it fails.

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

checkNotLite

private static <MessageT extends GeneratedMessage.ExtendableMessage<MessageT>, T>
Extension<MessageT,T> checkNotLite(ExtensionLite<? extends MessageT, T> extension)
