Member functions

Function name	Return type	Input type	Description
has_group_handle() const	bool	void	Returns true if group_handle is set.
group_handle()	const MapGroupHandle&	void	Returns the current value of group_handle. If group_handle is not set, returns a MapGroupHandle with none of its fields set (possibly group_handle::default_instance()).
mutable_group_handle()	MapGroupHandle *	void	Returns a pointer to the mutable MapGroupHandle object that stores the field's value. If the field was not set prior to the call, then the returned MapGroupHandle will have none of its fields set (i.e. it will be identical to a newly-allocated MapGroupHandle). After calling this, has_group_handle() will return true and group_handle() will return a reference to the same instance of MapGroupHandle.
clear_group_handle()	void	void	Clears the value of the field. After calling this, has_group_handle() will return false and group_handle() will return the default value.
set_allocated_group_handle()	void	MapGroupHandle *	Sets the MapGroupHandle object to the field and frees the previous field value if it exists. If the MapGroupHandle pointer is not NULL, the message takes ownership of the allocated MapGroupHandle object and has_ MapGroupHandle() will return true. Otherwise, if the group_handle is NULL, the behavior is the same as calling clear_group_handle().
release_group_handle()	MapGroupHandle *	void	Releases the ownership of the field and returns the pointer of the MapGroupHandle object. After calling this, caller takes the ownership of the allocated MapGroupHandle object, has_group_handle() will return false, and group_handle() will return the default value.
name()	const string&	void	Returns the current value of name. If name is not set, returns the empty string/empty bytes.
set_name()	void	const string&	Sets the value of name. After calling this, name() will return a copy of value.
set_name()	void	string&&	(C++11 and beyond): Sets the value of name, moving from the passed string. After calling this, name() will return a copy of value.
set_name()	void	const char*	Sets the value of name using a C-style null-terminated string. After calling this, name() will return a copy of value.
mutable_name()	string *	void	Returns a pointer to the mutable string object that stores name's value. If the field was not set prior to the call, then the returned string will be empty. After calling this, name() will return whatever value is written into the given string.
clear_name()	void	void	Clears the value of name. After calling this, name() will return the empty string/empty bytes.
set_allocated_name()	void	string*	Sets the string object to the field and frees the previous field value if it exists. If the string pointer is not NULL, the message takes ownership of the allocated string object. The message is free to delete the allocated string object at any time, so references to the object may be invalidated. Otherwise, if the value is NULL, the behavior is the same as calling clear_name().
release_name()	string *	void	Releases the ownership of name and returns the pointer of the string object. After calling this, caller takes the ownership of the allocated string object and name() will return the empty string/empty bytes.
has_related_mapping_handle() const	bool	void	Returns true if related_mapping_handle is set.
related_mapping_handle()	const MappingHandle&	void	Returns the current value of related_mapping_handle. If related_mapping_handle is not set, returns a MappingHandle with none of its fields set (possibly related_mapping_handle::default_instance()).
mutable_related_mapping_handle()	MappingHandle *	void	Returns a pointer to the mutable MappingHandle object that stores the field's value. If the field was not set prior to the call, then the returned MappingHandle will have none of its fields set (i.e. it will be identical to a newly-allocated MappingHandle). After calling this, has_related_mapping_handle() will return true and related_mapping_handle() will return a reference to the same instance of MappingHandle.
clear_related_mapping_handle()	void	void	Clears the value of the field. After calling this, has_related_mapping_handle() will return false and related_mapping_handle() will return the default value.
set_allocated_related_mapping_handle()	void	MappingHandle *	Sets the MappingHandle object to the field and frees the previous field value if it exists. If the MappingHandle pointer is not NULL, the message takes ownership of the allocated MappingHandle object and has_ MappingHandle() will return true. Otherwise, if the related_mapping_handle is NULL, the behavior is the same as calling clear_related_mapping_handle().
release_related_mapping_handle()	MappingHandle *	void	Releases the ownership of the field and returns the pointer of the MappingHandle object. After calling this, caller takes the ownership of the allocated MappingHandle object, has_related_mapping_handle() will return false, and related_mapping_handle() will return the default value.
has_parent_group_handle() const	bool	void	Returns true if parent_group_handle is set.
parent_group_handle()	const MapGroupHandle&	void	Returns the current value of parent_group_handle. If parent_group_handle is not set, returns a MapGroupHandle with none of its fields set (possibly parent_group_handle::default_instance()).
mutable_parent_group_handle()	MapGroupHandle *	void	Returns a pointer to the mutable MapGroupHandle object that stores the field's value. If the field was not set prior to the call, then the returned MapGroupHandle will have none of its fields set (i.e. it will be identical to a newly-allocated MapGroupHandle). After calling this, has_parent_group_handle() will return true and parent_group_handle() will return a reference to the same instance of MapGroupHandle.
clear_parent_group_handle()	void	void	Clears the value of the field. After calling this, has_parent_group_handle() will return false and parent_group_handle() will return the default value.
set_allocated_parent_group_handle()	void	MapGroupHandle *	Sets the MapGroupHandle object to the field and frees the previous field value if it exists. If the MapGroupHandle pointer is not NULL, the message takes ownership of the allocated MapGroupHandle object and has_ MapGroupHandle() will return true. Otherwise, if the parent_group_handle is NULL, the behavior is the same as calling clear_parent_group_handle().
release_parent_group_handle()	MapGroupHandle *	void	Releases the ownership of the field and returns the pointer of the MapGroupHandle object. After calling this, caller takes the ownership of the allocated MapGroupHandle object, has_parent_group_handle() will return false, and parent_group_handle() will return the default value.
children_map_group_handles_size() const	int	void	Returns the number of elements currently in the field.
children_map_group_handles() const	const MapGroupHandle	int index	Returns the element at the given zero-based index. Calling this method with index outside of [0, children_map_group_handles_size()) yields undefined behavior.
mutable_children_map_group_handles()	MapGroupHandle*	int index	Returns a pointer to the mutable MapGroupHandle object that stores the value of the element at the given zero-based index. Calling this method with index outside of [0, children_map_group_handles_size()) yields undefined behavior.
