Method Increment

sessions/session.go:267–272

Increment increments the stored int value saved as "key" by +"n". If value doesn't exist on that "key" then it creates one with the "n" as its value. It returns the new, incremented, value.

(key string, n int)

// If value doesn't exist on that "key" then it creates one with the "n" as its value.
// It returns the new, incremented, value.
func (s *Session) Increment(key string, n int) (newValue int) {
	newValue = s.GetIntDefault(key, 0)
	newValue += n
	s.Set(key, newValue)
	return
}

// Decrement decrements the stored int value saved as "key" by -"n".
// If value doesn't exist on that "key" then it creates one with the "n" as its value.
