All Known Implementing Classes:

AccumulateProjector, EmptyProjector, SimpleVolatileProjector, VolatileHierarchyProjector
```
public interface VolatileProjector
```
Render a 2D target copying pixels from a nD source.
Rendering can be interrupted, in which case map(boolean) will return false. Also, the rendering time for the last map(boolean) can be queried.

- Method Detail
  - map
```
boolean map(boolean clearUntouchedTargetPixels)
```
    Render the target image.
    
    Parameters:
    
    clearUntouchedTargetPixels -
    
    Returns:
    
    true if rendering was completed (all target pixels written). false if rendering was interrupted.
  - map
```
default boolean map()
```
  - cancel
```
void cancel()
```
    Abort map() if it is currently running.
  - getLastFrameRenderNanoTime
```
long getLastFrameRenderNanoTime()
```
    How many nano-seconds did the last map() take.
    
    Returns:
    
    time needed for rendering the last frame, in nano-seconds.
  - isValid
```
boolean isValid()
```
    Returns:
    
    true if all mapped pixels were valid.
