Class DoubleArray

java.lang.Object

  +--Util.DoubleArray

public class DoubleArray

extends java.lang.Object

This class implements an array of doubles in a similar way ArrayLists are implemented. They serve to decrease memory space (as opposed to ArrayLists) and allow functions directly operate on doubles.
The working will further not be discussed here.
