Class DescriptorProtos.OneofDescriptorProto.Builder (3.19.4)

Describes a oneof.

Protobuf type google.protobuf.OneofDescriptorProto

Called by the initialization and clear code paths to allow subclasses to reset any of their builtin fields back to the initial values.

optional string name = 1;

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

optional .google.protobuf.OneofOptions options = 2;

Clones the Builder.

Get an instance of the type with no fields set. Because no fields are set, all getters for singular fields will return default values and repeated fields will appear empty. This may or may not be a singleton. This differs from the getDefaultInstance() method of generated message classes in that this method is an abstract method of the MessageLite interface whereas getDefaultInstance() is a static method of a specific class. They return the same thing.

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.

optional string name = 1;

optional .google.protobuf.OneofOptions options = 2;

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

Like Builder#mergeFrom(CodedInputStream), but also parses extensions. The extensions that you want to be able to parse must be registered in extensionRegistry. Extensions not in the registry will be treated as unknown fields.

Merge other into the message being built. other must have the exact same type as this (i.e. getDescriptorForType() == other.getDescriptorForType()).

Merging occurs as follows. For each field:

• For singular primitive fields, if the field is set in other, then other's value overwrites the value in this message.
  
• For singular message fields, if the field is set in other, it is merged into the corresponding sub-message of this message using the same merging rules.
  
• For repeated fields, the elements in other are concatenated with the elements in this message.
  

• For oneof groups, if the other message has one of the fields set, the group of this message is cleared and replaced by the field of the other message, so that the oneof constraint is preserved.

  This is equivalent to the Message::MergeFrom method in C++.

optional .google.protobuf.OneofOptions options = 2;

Merge some unknown fields into the UnknownFieldSet for this message.
