Functions

func CreatePrefixList 

func CreatePrefixList(pkg string) []string

CreatePrefixList returns a list of package prefixes to search when resolving a symbol name. If the given package is blank, it returns only the empty string. If the given package contains only one token, e.g. "foo", it returns that token and the empty string, e.g. ["foo", ""]. Otherwise, it returns successively shorter prefixes of the package and then the empty string. For example, for a package named "foo.bar.baz" it will return the following list: 

["foo.bar.baz", "foo.bar", "foo", ""]

func GetMaxTag 

func GetMaxTag(isMessageSet bool) int32

GetMaxTag returns the max tag number allowed, based on whether a message uses message set wire format or not.

func GetProto3Optional 

func GetProto3Optional(fd *dpb.FieldDescriptorProto) bool

func InitCap 

func InitCap(name string) string

InitCap returns the given field name, but with the first letter capitalized.

func JsonName 

func JsonName(name string) string

JsonName returns the default JSON name for a field with the given name.

func PopulateSourceInfoMap 

func PopulateSourceInfoMap(fd *dpb.FileDescriptorProto, m SourceInfoMap)

PopulateSourceInfoMap populates the given SourceInfoMap with information from the given file descriptor.

func ProcessProto3OptionalFields 

func ProcessProto3OptionalFields(msgd *dpb.DescriptorProto)

ProcessProto3OptionalFields adds synthetic oneofs to the given message descriptor for each proto3 optional field. It also updates the fields to have the correct oneof index reference.

func RecomputeSourceInfo 

func RecomputeSourceInfo(c SourceInfoComputer)

RecomputeSourceInfo is used to initiate recomputation of source info. This is is used by the protoparse package, after it interprets options.

func SetProto3Optional 

func SetProto3Optional(fd *dpb.FieldDescriptorProto)

Types

type SourceInfoComputeFunc 

type SourceInfoComputeFunc func()

SourceInfoComputeFunc is the type that a desc.Descriptor will embed. It will be aliased in the desc package to an unexported name so it is not marked as an exported field in reflection and not present in Go docs.

type SourceInfoComputer 

type SourceInfoComputer interface {
	// contains filtered or unexported methods
}

SourceInfoComputer is a single method which will be invoked to recompute source info. This is needed for the protoparse package, which needs to link descriptors without source info in order to interpret options, but then needs to re-compute source info after that interpretation so that final linked descriptors expose the right info.

type SourceInfoMap 

type SourceInfoMap map[string][]*dpb.SourceCodeInfo_Location

SourceInfoMap is a map of paths in a descriptor to the corresponding source code info.

func CreateSourceInfoMap 

func CreateSourceInfoMap(fd *dpb.FileDescriptorProto) SourceInfoMap

CreateSourceInfoMap constructs a new SourceInfoMap and populates it with the source code info in the given file descriptor proto.

func (SourceInfoMap) Add 

func (m SourceInfoMap) Add(path []int32, loc *dpb.SourceCodeInfo_Location)

Add stores the given source code info for the given path.

func (SourceInfoMap) Get 

func (m SourceInfoMap) Get(path []int32) *dpb.SourceCodeInfo_Location

Get returns the source code info for the given path. If there are multiple locations for the same path, the first one is returned.

func (SourceInfoMap) GetAll 

func (m SourceInfoMap) GetAll(path []int32) []*dpb.SourceCodeInfo_Location

GetAll returns all source code info for the given path.

func (SourceInfoMap) PutIfAbsent 

func (m SourceInfoMap) PutIfAbsent(path []int32, loc *dpb.SourceCodeInfo_Location) bool

PutIfAbsent stores the given source code info for the given path only if the given path does not exist in the map. This method returns true when the value is stored, false if the path already exists.
