** Defs are upb's internal representation of the constructs that can appear |
|
** in a .proto file: |
|
** |
|
** - upb::MessageDef (upb_msgdef): describes a "message" construct. |
|
** - upb::FieldDef (upb_fielddef): describes a message field. |
|
** - upb::FileDef (upb_filedef): describes a .proto file and its defs. |
|
** - upb::EnumDef (upb_enumdef): describes an enum. |
|
** - upb::OneofDef (upb_oneofdef): describes a oneof. |
|
** - upb::Def (upb_def): base class of all the others. |
|
** |
|
** TODO: definitions of services. |
|
** |
|
** Like upb_refcounted objects, defs are mutable only until frozen, and are |
|
** only thread-safe once frozen. |
|
** |
|
** This is a mixed C/C++ interface that offers a full API to both languages. |
|
** See the top-level README for more information. |
