Class Prefetcher

java.lang.Object
skyview.process.Processor
skyview.process.imagefinder.Prefetcher
All Implemented Interfaces:
java.io.Serializable, Component

public class Prefetcher
extends Processor
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.

    • process

      public void process​(Image[] inputs, Image output, int[] source, Sampler samp, DepthSampler dsamp)
      Description copied from class: Processor
      Perform the processing task associated with this object.
      Specified by:
      process in class Processor
      Parameters:
      inputs - 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 - The sampler in the energy dimension (often null).
    • updateHeader

      public void updateHeader​(nom.tam.fits.Header header)
      Update the FITS header to indicate what processing was done.
