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.

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
Description copied from interface:MessageOrBuilder
Get the message's type's descriptor. This differs from thegetDescriptor()
method of generated message classes in that this method is an abstract method of theMessage
interface whereasgetDescriptor()
is a static method of a specific class. They return the same thing.- Specified by:

in interfaceMessageOrBuilder
-
mergeFromAndMakeImmutableInternal
@Deprecated protected void mergeFromAndMakeImmutableInternal(CodedInputStream input, ExtensionRegistryLite extensionRegistry) throws InvalidProtocolBufferException Deprecated.use newBuilder().mergeFrom() insteadTODO: 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
-
getAllFieldsMutable
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 implementgetAllFields()
.- 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.- Specified by:
isInitialized
in interfaceMessageLiteOrBuilder
- Overrides:
isInitialized
in classAbstractMessage
-
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 callingMessageOrBuilder.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 interfaceMessageOrBuilder
-
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 callinggetFieldRaw(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. -

Returns true if the given oneof is set.- Specified by:
hasOneof
in interfaceMessageOrBuilder
- Overrides:
hasOneof

-
getOneofFieldDescriptor
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 interfaceMessageOrBuilder
- Overrides:
getOneofFieldDescriptor
in classAbstractMessage
-
hasField
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 interfaceMessageOrBuilder
-
getField
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 interfaceMessageOrBuilder
-
getFieldRaw
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
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 interfaceMessageOrBuilder
-
getRepeatedField
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:

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:

getMethodOrDie
Calls Class.getMethod and throws a RuntimeException if it fails. -
invokeOrDie
Calls invoke and throws a RuntimeException if it fails. -
internalGetMapFieldReflection
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.TODO: Remove, exists for compatibility with generated code. -
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 callingreturn super.writeReplace();
