Naming of update method

[callum]

Hi,

I'm just curious how whatever script is controlling the overall window knows what method to call on the visual.

When creating a new visual, by default the name of the method is "update", so at first I assumed that it would simply be the "update" method that got called every time.

But then I was looking through the source code of the built-in map visual and it has no method called update. Instead there's methods like updateInternal. So how is it determined which method needs to be called on update?

Thanks

@callum,

The repository is deprecated. Look at the module, it is module powerbi.visuals, not module powerbi.extensibility.visual. The update method might be optional.

The update method was optional for the legacy API.

However, this method is required for cusom visuals that based on the new API.
