org.apache.mahout.math.list.IntArrayList.elements()
Returns the elements currently stored, including invalid elements between size and capacity, if any. WARNING: For efficiency reasons and to keep memory usage low, the array is not copied. So if subsequently you modify the returned array directly via the [] operator, be sure you know what you're doing. @return the elements currently stored.
