DataFormat for tiles?

[ahinchman1]

I am writing a Kotlin/TornadoFX app using TilesFX, and I've reached the point where I'm ready to interact with them. I created a DataFormat such that

private var TILES: DataFormat = DataFormat("eu.hansolo.tilesfx.Tile")

But in my java app, it says

java.lang.IllegalArgumentException: DataFormat 'eu.hansolo.tilesfx.Tile' already exists.

Is there an existing DataFormat for a tile in TilesFX?

Update: I was able to progress using a companion object. I just have to figure out how I can either cast Tile to be serializable or be a BufferByte
