Member functions

Function name	Return type	Input type	Description
finger_size() const	int	void	Returns the number of elements currently in the field.
finger() const	const Finger	int index	Returns the element at the given zero-based index. Calling this method with index outside of [0, finger_size()) yields undefined behavior.
mutable_finger()	Finger*	int index	Returns a pointer to the mutable Finger object that stores the value of the element at the given zero-based index. Calling this method with index outside of [0, finger_size()) yields undefined behavior.
add_finger()	Finger*	void	Adds a new element and returns a pointer to it. The returned Finger is mutable and will have none of its fields set (i.e. it will be identical to a newly-allocated Finger).
clear_finger()	void	void	Removes all elements from the field. After calling this, finger_size() will return zero.
finger() const	const RepeatedPtrField< Finger>&	void	Returns the underlying RepeatedPtrField that stores the field's elements. This container class provides STL-like iterators and other methods.
mutable_finger()	RepeatedPtrField< Finger>*	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.
