Class SegmentSplitter

java.lang.Object

hlcd.testing.arrayTester.SegmentSplitter

public class SegmentSplitter
extends Object

Uses a 1-D array of ints to mimic the splitting of segments. The length of the array represents the number of segments required. The value stored in each cell represents the length the segment.

 //minimal example to execute this class:
 public static void main(String[] args) {
     System.out.println("Running SegmentSplitter...");
     //number of complete 1D arrays
     long fullSegments = (long) (Math.random() * 100000);
     //extra is a value between 0 and maxSegmentLength, including both
     long extra = (long) (Math.random() * (MAX_SEGMENT_LENGTH + 1));

     long size = fullSegments * MAX_SEGMENT_LENGTH + extra;

     double sizeInGb = (64 * size) / 8000000000.0;
     //System.out.println("Total GBs of RAM used: " + sizeInGb);

     SegmentSplitter data = new SegmentSplitter(size);
     System.out.println("The size of each segment in the 2-D array: ");
     System.out.println(data);

     //count the number of cells allocated
     long cells = 0;
     for (int i = 0; i < data.array.length; i++) {
         cells += data.array[i];
     }
     //ensure the number of allocated cells matches the size specified
     if (size != cells) {
         System.out.println("Failed.");
     }else{
         System.out.println("Success!");
     }
     System.out.println("SegmentSplitter completed.");
 }
