RasterLayer

Represents a Raster Layer that can give detailed information about the Raster it represents, cache the raster, and get the raster cropped to an extent or at a different resolution.

This represents a layer in a bound Context, not an abstract representation of the Raster. In other words, if you are holding one of these objects, then the code that uses it should only execute on the machine that the RasterLayer is from. If you pass around RasterLayers, you will be passing around the cache as well, which is not ideal.

To implement a new RasterLayer, inherit from this class, implement the cache(c: Cache) method for caching the raster layer, and implement the getRaster() (for getting a Raster with it's native RasterExtent) and getRaster(rasterExtent: RasterExtent) (for getting a Raster at a different extent\resolution). Optionally you can override getRaster(extent: Extent), which by default just creates a RasterExtent with that extent snapped to the raster's native resolution.
