Member functions

Function name	Return type	Input type	Description
has_command_id() const	bool	void	Returns true if command_id is set.
command_id()	const MessageId&	void	Returns the current value of command_id. If command_id is not set, returns a MessageId with none of its fields set (possibly command_id::default_instance()).
mutable_command_id()	MessageId *	void	Returns a pointer to the mutable MessageId object that stores the field's value. If the field was not set prior to the call, then the returned MessageId will have none of its fields set (i.e. it will be identical to a newly-allocated MessageId). After calling this, has_command_id() will return true and command_id() will return a reference to the same instance of MessageId.
clear_command_id()	void	void	Clears the value of the field. After calling this, has_command_id() will return false and command_id() will return the default value.
set_allocated_command_id()	void	MessageId *	Sets the MessageId object to the field and frees the previous field value if it exists. If the MessageId pointer is not NULL, the message takes ownership of the allocated MessageId object and has_ MessageId() will return true. Otherwise, if the command_id is NULL, the behavior is the same as calling clear_command_id().
release_command_id()	MessageId *	void	Releases the ownership of the field and returns the pointer of the MessageId object. After calling this, caller takes the ownership of the allocated MessageId object, has_command_id() will return false, and command_id() will return the default value.
flags()	uint32	void	Returns the current value of flags. If the flags is not set, returns 0.
set_flags()	void	uint32	Sets the value of flags. After calling this, flags() will return value.
clear_flags()	void	void	Clears the value of flags. After calling this, flags() will return 0.
motor_cmd_size() const	int	void	Returns the number of elements currently in the field.
motor_cmd() const	const MotorCommand	int index	Returns the element at the given zero-based index. Calling this method with index outside of [0, motor_cmd_size()) yields undefined behavior.
mutable_motor_cmd()	MotorCommand*	int index	Returns a pointer to the mutable MotorCommand object that stores the value of the element at the given zero-based index. Calling this method with index outside of [0, motor_cmd_size()) yields undefined behavior.
add_motor_cmd()	MotorCommand*	void	Adds a new element and returns a pointer to it. The returned MotorCommand is mutable and will have none of its fields set (i.e. it will be identical to a newly-allocated MotorCommand).
clear_motor_cmd()	void	void	Removes all elements from the field. After calling this, motor_cmd_size() will return zero.
motor_cmd() const	const RepeatedPtrField< MotorCommand>&	void	Returns the underlying RepeatedPtrField that stores the field's elements. This container class provides STL-like iterators and other methods.
mutable_motor_cmd()	RepeatedPtrField< MotorCommand>*	void	Returns a pointer to the underlying mutable RepeatedPtrField that stores the field's elements. This container class provides STL-like iterators and other methods.
