Member functions

Function name	Return type	Input type	Description
has_handle() const	bool	void	Returns true if handle is set.
handle()	const ControllerHandle&	void	Returns the current value of handle. If handle is not set, returns a ControllerHandle with none of its fields set (possibly handle::default_instance()).
mutable_handle()	ControllerHandle *	void	Returns a pointer to the mutable ControllerHandle object that stores the field's value. If the field was not set prior to the call, then the returned ControllerHandle will have none of its fields set (i.e. it will be identical to a newly-allocated ControllerHandle). After calling this, has_handle() will return true and handle() will return a reference to the same instance of ControllerHandle.
clear_handle()	void	void	Clears the value of the field. After calling this, has_handle() will return false and handle() will return the default value.
set_allocated_handle()	void	ControllerHandle *	Sets the ControllerHandle object to the field and frees the previous field value if it exists. If the ControllerHandle pointer is not NULL, the message takes ownership of the allocated ControllerHandle object and has_ ControllerHandle() will return true. Otherwise, if the handle is NULL, the behavior is the same as calling clear_handle().
release_handle()	ControllerHandle *	void	Releases the ownership of the field and returns the pointer of the ControllerHandle object. After calling this, caller takes the ownership of the allocated ControllerHandle object, has_handle() will return false, and handle() will return the default value.
event_type() const	uint32	void	Returns the current value of event_type. If the event_type is not set, returns 0.
set_event_type()	void	uint32	Sets the value of event_type. After calling this, event_type() will return value.
clear_event_type()	void	void	Clears the value of event_type. After calling this, event_type() will return the empty string/empty bytes.
