SurfaceObjectTileBuilder.SurfaceObjectTileStateKey (NASA WorldWind)

java.lang.Object
- gov.nasa.worldwind.render.SurfaceObjectTileBuilder.SurfaceObjectTileStateKey

All Implemented Interfaces:

Cacheable

Enclosing class:

SurfaceObjectTileBuilder
```
protected static class SurfaceObjectTileBuilder.SurfaceObjectTileStateKey
extends java.lang.Object
implements Cacheable
```
Represents a surface renderable tile's current state. TileStateKey distinguishes the tile's state by comparing the individual state keys of the surface renderables intersecting the tile. This does not retain any references to the surface renderables themselves. Should the tile state key live longer than the surface renderables, the state key does not prevent those objects from being reclaimed by the garbage collector.

public SurfaceObjectTileStateKey(DrawContext dc,
                                 SurfaceObjectTileBuilder.SurfaceObjectTile tile)
```
    Construsts a tile state key for the specified surface renderable tile.
    
    Parameters:
    
    dc - the draw context the state key is related to.
    
    tile - the tile to construct a state key for.

  - getSizeInBytes
```
public long getSizeInBytes()
```
    Returns the tile state key's size in bytes. The total size of the intersecting object keys, plus the size of the array itself. The tileKey is owned by the SurfaceObjectTile, so we don't include it in the state key's size.

    Returns:
    
    The state key's size in bytes.
