Class Prefetcher

  • All Implemented Interfaces:
    java.io.Serializable, Component, Processor

    public class Prefetcher
    extends java.lang.Object
    implements 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.

        Description copied from interface: Processor
        Perform the processing task associated with this object.
        Specified by:
        process in interface 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).
