Detailed Description

Describes a single field in a message.

Field Documentation

name

const char* ProtobufCFieldDescriptor::name

Name of the field as given in the .proto file.

id

uint32_t ProtobufCFieldDescriptor::id

Tag value of the field as given in the .proto file.

label

ProtobufCLabel ProtobufCFieldDescriptor::label

Whether the field is REQUIRED, OPTIONAL, or REPEATED.

type

ProtobufCType ProtobufCFieldDescriptor::type

The type of the field.

quantifier_offset

unsigned ProtobufCFieldDescriptor::quantifier_offset

The offset in bytes of the message's C structure's quantifier field (the has_MEMBER field for optional members or the n_MEMBER field for repeated members or the case enum for oneofs).

offset

unsigned ProtobufCFieldDescriptor::offset

The offset in bytes into the message's C structure for the member itself.

descriptor

const void* ProtobufCFieldDescriptor::descriptor

A type-specific descriptor.

If type is PROTOBUF_C_TYPE_ENUM, then descriptor points to the corresponding ProtobufCEnumDescriptor.

If type is PROTOBUF_C_TYPE_MESSAGE, then descriptor points to the corresponding ProtobufCMessageDescriptor.

Otherwise this field is NULL.

default_value

const void* ProtobufCFieldDescriptor::default_value

The default value for this field, if defined.

May be NULL.

flags

uint32_t ProtobufCFieldDescriptor::flags

A flag word.

Zero or more of the bits defined in the ProtobufCFieldFlag enum may be set.

reserved_flags

unsigned ProtobufCFieldDescriptor::reserved_flags

Reserved for future use.

reserved2

void* ProtobufCFieldDescriptor::reserved2

Reserved for future use.

reserved3

void* ProtobufCFieldDescriptor::reserved3

Reserved for future use.
