PresentableState (openjfx 8.0.202 API)

java.lang.Object
- com.sun.prism.PresentableState

```
public abstract class PresentableState
extends Object
```
PresentableState is intended to provide for a shadow copy of View/Window state for use off the event thread. It is the task of the invoker of Prism to make sure that the state is consistent for a rendering probably by use of the AbstractPainter.renderLock to ensure consistent state.
