Public Member Functions
void	Visit (google::protobuf::Message &message, Callback callback)
	Execute a callback without recursion.
void	VisitRecursive (google::protobuf::Message &message, Callback callback)
	Execute a callback recursively.
void	Compile (const google::protobuf::Descriptor *descriptor)
	Compiles the visitor for the given message type and its dependent types.
void	Compile (const DescriptorList &descriptors)
	Compiles the visitor for the given message types and their dependent types.
void	CompileAllGenerated ()
	Compiles the visitor for all message types we can find. Not guaranteed to find all message types.
void	CompileGenerated (std::string_view message_name)
	Compiles the visitor for the given generated message type and its dependent types.
void	CompileGenerated (utils::span< std::string_view > message_names)
	Compiles the visitor for the given generated message type and their dependent types.
bool	ContainsSelected (const google::protobuf::Descriptor *descriptor)
	Efficiently checks if the message contains any selected structures.
virtual void	CompileOne (const google::protobuf::Descriptor &descriptor)=0
	Compile one message without nested.
virtual bool	IsSelected (const google::protobuf::Descriptor &) const =0
	Checks if the message is selected or has anything selected.

Protected Member Functions

LockBehavior

enum class ugrpc::VisitorCompiler::LockBehavior

stronginherited

Enumerator
kNone	Do not take shared_mutex locks for any operation on the visitor.
kShared	Take shared_lock for all read operations on the visitor and unique_lock for all Compile operations.

Member Function Documentation

ContainsSelected()

bool ugrpc::VisitorCompiler::ContainsSelected ( const google::protobuf::Descriptor * descriptor )

inherited

Efficiently checks if the message contains any selected structures.

You may want to call this before BaseVisitor::Visit and BaseVisitor::VisitRecursive to avoid a copy of the message beforehand if you require one.

Visit()

template<typename Callback>

void ugrpc::BaseVisitor< Callback >::Visit ( google::protobuf::Message & message, Callback callback )

inline

Execute a callback without recursion.

Equivalent to VisitFields but utilizes the precompilation data from Compile

Definition at line 176 of file protobuf_visit.hpp.

VisitRecursive()

template<typename Callback>

void ugrpc::BaseVisitor< Callback >::VisitRecursive ( google::protobuf::Message & message, Callback callback )

inline

Execute a callback recursively.

Equivalent to VisitFieldsRecursive and VisitMessagesRecursive but utilizes the precompilation data from Compile
