java.lang.Object skyview.process.imagefinder.Prefetcher
public class Prefetcher
This class makes sure that all of the candidate images are actually present and then if any candidate was not already in the cache is redoes the image finding using the standard image finder. This accommodate cases where the proxy geometry is not a good approximation to the real geometry. It still requires that the image selection be done reasonably well.

- The array of input survey images.output
- The output user image. A null output may signal
that an error has taken place. If this processor wishes
to do something in response to the error, it may look at the ErrorMsg setting.source
- An array giving the source image for each output pixel.samp
- The sampler object used to do spatial sampling of the input images.dsamp
