Summary:
Changelog: [Internal] - Refactor JSPointerDispatcher to group secondary actions (pointer_up, pointer_down) to use same logic and emit non-direct events
This diff re-arranges some code and re-uses some logic for different MotionEvent types.
Specifically, before our code for handling a motionEvent looked like
```
func onMotionEvent(event) {
if (event is HOVER_MOVE) {
handleHoverEvent(event)
}
if (event is ACTION_DOWN) {
// logic for dispatching down, enter, over
}
if (event is ACTION_POINTER_DOWN) { // this represents any secondary pointer going down
// logic for dispatching down
}
if (event is ACTION_MOVE) {
// logic for dispatching touch move
}
if (event is ACTION_UP) {
// logic for dispatching up, out, leave
}
if (event is ACTION_POINTER_UP) { // this represents any secondary pointer going up
// logic for dispatching up
}
....
}
```
now, we've refactored it to be like:
```
func onMotionEvent(event) {
if (event is HOVER_MOVE) { // Still keep this as separate because it does some special things. Will refactor in follow-up diff
handleHoverEvent(event)
}
switch() {
case ACTION_DOWN or ACTION_POINTER_DOWN:
// do same logic
break;
case ACTION_UP or ACTION_POINTER_UP:
// do same logic
break;
case ACTION_MOVE:
// do same logic, we will want to converge this logic with HOVER_MOVE, todo in a follow-up
break;
...
}
....
}
```
This refactor adds the functionality of `enter, over, out, leave` to secondary pointer events in which they weren't fired before.
