  - getCacheKey
```
 final String getCacheKey(String documentHash, Integer page, RectF bounds, Float zoom)
```
    Generate a unique cache key for a tile.
    
    Parameters:
    
    documentHash - Unique identifier for the document (e.g.
    
    page - Page index
    
    bounds - Tile bounds (relative coordinates)
    
    zoom - Zoom level
  - hasTile
```
 final Boolean hasTile(String cacheKey)
```
    Check if a tile exists in disk cache.
  - loadTile
```
 final Bitmap loadTile(String cacheKey)
```
    Load a tile from disk cache.
  - saveTile
```
 final Unit saveTile(String cacheKey, Bitmap bitmap)
```
    Save a tile to disk cache synchronously.
  - saveTileAsync
```
 final Unit saveTileAsync(String cacheKey, Bitmap bitmap)
```
    Save a tile asynchronously to avoid blocking render thread. Creates a copy of the bitmap since original may be recycled.
  - clearCache
```
 final Unit clearCache()
```
    Clear all cached tiles.
  - clearDocument
```
 final Unit clearDocument(String documentHash)
```
    Clear cache for a specific document.
  - getCacheSize
```
 final Long getCacheSize()
```
    Get current cache size in bytes.
  - shutdown
```
 final Unit shutdown()
```
    Shutdown the executor when no longer needed.
