class DescriptorNames

Defined at line 243 of file ../../third_party/protobuf/src/src/google/protobuf/descriptor.h

This class is used to index into the memory it is pointing at.

The layout is as follows:

[ chars .... ] [ data0 (uint16_t) ] [ ... ] [ dataN (uint16_t) ]

payload_ points here

The offsets are relative to payload_.

The offsets are as follows:

(0) `name` size. `name` ends at `payload_`

(1) `full_name` size. `full_name` ends at `payload_` and shares bytes with

`name`.

.. the following offsets only available for `FieldDescriptor` ..

(2)/(3) `lowercase` offset/size. The data bytes could be shared.

(4)/(5) `camelcase` offset/size. The data bytes could be shared.

(6)/(7) `json_name` offset/size. The data bytes could be shared.

NOTE ABOUT NULL TERMINATION:

The name accessors were migrated from `std::string` to `absl::string_view`,

which caused valid code to break. In particular, there are previously

correct callers calling `foo.name().data()` and using it as a NULL

terminated C-string.

To prevent further breakage we are adding null termination on all these

names even though it is outside the contract for `absl::string_view`.

This might change in the future.

Public Methods

void DescriptorNames ()

Uninitialized, to support `= default` of descriptor types.

void DescriptorNames (const char * payload)

Defined at line 247 of file ../../third_party/protobuf/src/src/google/protobuf/descriptor.h

absl::string_view name ()

The full name is just before `payload_`, and the name is the suffix of it.

We don't need a special offset for them.

NOTE: the sizes don't include the null terminator, so add +1 to the offset.

absl::string_view full_name ()

Defined at line 255 of file ../../third_party/protobuf/src/src/google/protobuf/descriptor.h

absl::string_view lowercase_name ()

Only available for `FieldDescriptor`. This is not checked at runtime.

NOTE: The offsets here already take into account the null terminator.
