[VTM] make getRules() in RenderTheme public and maybe add a setter

[Karsten T.]

Hello,

I want to make getRules() in RenderTheme public, so I can access rules for existing themes to create new themes.

I don't know how the rules work, but a setter method would also be nice.

The rules variable is final in the RenderTheme.

You can use the RenderTheme.traverseRules method to modify them.
See the ThemeStylerActivity and the RuleVisitorTest examples.

Or use a TileLoaderThemeHook, see the MapsforgeActivity example.

i ended up using this approach and it works, thanks. one question remains: in my current implementation i'm only resetting the TextStyle - does this have a negative impact on performance or can i even remove the TextStyle? i didn't try to remove the style yet because styles in Rule is also final

If you want to hide a rule you could try the TileLoaderThemeHook (see the MapsforgeActivity).

Check for your key / value tag and the needed style and could return true to skip it.


But you just have to customize your own theme instead of reverse engineering with code.
