Examples of org.apache.mahout.math.list.ShortArrayList

org.apache.mahout.math.list.ShortArrayList
Resizable list holding short elements; implemented with arrays.

  /**
   * Returns a string representation of the receiver, containing the String representation of each key-value pair,
   * sorted ascending by key.
   */
  public String toString() {
    ShortArrayList theKeys = keys();
    //theKeys.sort();


    StringBuilder buf = new StringBuilder();
    buf.append('[');
    int maxIndex = theKeys.size() - 1;
    for (int i = 0; i <= maxIndex; i++) {

      buf.append("->");
      buf.append(String.valueOf(get(key)));
