Get a nested builder instance for the given field.
Normally, we hold a reference to the immutable message object for the message type field.
Some implementations(the generated message builders), however, can also hold a reference to
the builder object (a nested builder) for the field.
If the field is already backed up by a nested builder, the nested builder will be
returned. Otherwise, a new field builder will be created and returned. The original message
field (if exist) will be merged into the field builder, which will then be nested into its
parent builder.
NOTE: implementations that do not support nested builders will throw
UnsupportedOperationException.
Get a nested builder instance for the given repeated field instance.

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.
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.
