Examples of ar.Transfer.specialize()

ar.Transfer.specialize()

Determine control parameter values for the passed set of a aggregates. This method should be called at least once before the first value of an aggregate set is presented to the transfer function. Some transfer functions rely on relationships that exist inside of an aggregate set. This method allows the transfer function to compute relevant relationship quantities once, and then use them multiple times in the "at" method. For example, high-definition alpha composition needs to know the maximum and minimum value in the dataset. "Specialize" will compute those maximum/minimum values. TODO: Java 8 -- default for specialized types is to return 'this' @param aggregates Aggregates to determine the parameters for.

        Aggregates<Integer> aggs = render.aggregate(glyphs, s, aggregator, vt, width, height);
        long end = System.currentTimeMillis();
        long aggTime = end-start;


        start = System.currentTimeMillis();
        Transfer.Specialized<Number,Color> ts = transfer.specialize(aggs);
        Aggregates<Color> colors = render.transfer(aggs, ts);
        end = System.currentTimeMillis();
        long transTime = end-start;


        aggs.get(0, 0);

      transfer = t;
    } else {
      transfer = transfers.get(0);
    }
    
    Transfer.Specialized ts = transfer.specialize(aggs);
    Aggregates<?> rslt = r.transfer(aggs, ts);
    return rslt;
  }
