Method Summary
`void` | `listUpdated()` Called when the provided OMGraphicList has another tile added to it, so the list can be repainted if the caller is interested in incremental updates.
`boolean` | `shouldContinue()` Asked by the MapTileFactory if the tile fetching should continue.

Method Detail

### listUpdated

    void listUpdated()

  Called when the provided OMGraphicList has another tile added to it, so the list can be repainted if the caller is interested in incremental updates.

### shouldContinue

    boolean shouldContinue()

  Asked by the MapTileFactory if the tile fetching should continue. Called during stable times, just to make sure that the currently fetched tile set is still wanted. Safe to always return true, but if you want the TileFactory to forget what it's doing (like the projection changed), then return false;

  Returns:
    true of the MapTileFactory should keep collecting tiles for the current request.
