RasterCache class

Handles Raster image caching.

You can cache your raster images for faster access in a RasterCache with the load() or loadAll() methods. Pogo provides a static RasterCache for general use in the Assets static class.

await Assets.rasterCache.loadAll(['player.png', 'enemy.png']);

Or, you can instantiate your own copy of a RasterCache if needed. But, given that you can clear and reload the static cache, the use case of needing your own cache may not be common.

Methods

clear	Clears all data from the cache.
get	Returns an image, by filename, from the cache.
load	Loads a single file into the cache. Returns a Raster Future.
loadAll	Loads a List of files into the cache. Returns a List Future.
remove	Removes a single image, by filename, from the cache.
setSubPath	Override the default subdirectory for image files. Must specify a path underneath assets/ (or set to empty for assets/ root). Default: images/.
