I am building an interface where the user updates the interface state by
clicking buttons. When a button is clicked it changes appearance to
indicate the state change.
For the purposes of my question imagine a button that first shows "A"
then when clicked changes to "B", then "C" and then "D". Clicking when
the button shows "D" moves the state back to "A".
It may be that the user clicks at "A" and keeps on clicking until they
reach "D" - so we have a series of state changes - A->B->C->D
The only thing that needs to be known is that the final state is "D". So
I need to save the update to "D", but not the intermediate values.
I am planning to run a timer that is reset on every click, so that when
the timer expires, the state is saved. The timer would only then restart
once clicking resumes. I would most likely also have a maximum "wait" too.
Is there an alternative pattern for this?
