hasProto3Optional
public boolean hasProto3Optional()If true, this is a proto3 "optional". When a proto3 field is optional, it tracks presence regardless of field type. When proto3_optional is true, this field must belong to a oneof to signal to old proto3 clients that presence is tracked for this field. This oneof is known as a "synthetic" oneof, and this field must be its sole member (each proto3 optional field gets its own synthetic oneof). Synthetic oneofs exist in the descriptor only, and do not generate any API. Synthetic oneofs must be ordered after all "real" oneofs. For message fields, proto3_optional doesn't create any semantic change, since non-repeated message fields always track presence. However it still indicates the semantic detail of whether the user wrote "optional" or not. This can be useful for round-tripping the .proto file. For consistency we give message fields a synthetic oneof also, even though it is not required to track presence. This is especially important because the parser can't tell if a field is a message or an enum, so it must always create a synthetic oneof. Proto2 optional fields do not set this flag, because they already indicate optional with `LABEL_OPTIONAL`.
optional bool proto3_optional = 17;
- Specified by:
hasProto3Optional
in interfaceDescriptorProtos.FieldDescriptorProtoOrBuilder
- Returns:
- Whether the proto3Optional field is set.

protected final Object dynamicMethod(GeneratedMessageLite.MethodToInvoke method, Object arg0, Object arg1) Description copied from class:GeneratedMessageLite

. These different kinds of operations are required to implement message-level operations for builders in the runtime. This method bundles those operations to reduce the generated methods count.NEW_INSTANCE
returns a new instance of the protocol buffer that has not yet been made immutable. SeeMAKE_IMMUTABLE
.IS_INITIALIZED
returnsnull
for false and the default instance for true. It doesn't use or modify any memoized value.GET_MEMOIZED_IS_INITIALIZED
returns the memoizedisInitialized
byte value.SET_MEMOIZED_IS_INITIALIZED
sets the memoizedisInitialized
byte value to 1 if the first parameter is not null, or to 0 if the first parameter is null.NEW_BUILDER
