Examples of cern.colt.list.DoubleArrayList

cern.colt.list.DoubleArrayList
Resizable list holding double elements; implemented with arrays. First see the package summary and javadoc tree view to get the broad picture.

  IntArrayList indexList = indexes[i];
  if (indexList != null) k = indexList.binarySearch(j);
  
  if (k>=0) { // found
    if (value==0) {
      DoubleArrayList valueList = values[i];
      indexList.remove(k);
      valueList.remove(k);
      int s = indexList.size();
      if (s>2 && s*3 < indexList.elements().length) {
        indexList.setSize(s*3/2);
        indexList.trimToSize();
        indexList.setSize(s);
        
        valueList.setSize(s*3/2);
        valueList.trimToSize();
        valueList.setSize(s);    
      }
    }
    else {
      values[i].setQuick(k,value);
    }
  }
  else { // not found
    if (value==0) return;


    k = -k-1;


    if (indexList == null) {
      indexes[i] = new IntArrayList(3);
      values[i]  = new DoubleArrayList(3);
    }
    indexes[i].beforeInsert(k,j);
    values[i].beforeInsert(k,value);
