public abstract class AbstractDoubleBigList
extends it.unimi.dsi.fastutil.doubles.AbstractDoubleCollection
implements DoubleBigList, it.unimi.dsi.fastutil.doubles.DoubleStack

An abstract class providing basic methods for big lists implementing a type-specific big list interface.

Most of the methods in this class are optimized with the assumption that the List will have have constant-time random access. If this is not the case, you should probably at least override listIterator(long) and the xAll() methods (such as addAll(long, java.util.Collection<? extends java.lang.Double>)) with a more appropriate iteration scheme. Note the subList(long, long) method is cognizant of random-access or not, so that need not be reimplemented.

Description copied from interface: DoubleBigList

Set (hopefully quickly) elements to match the array given. Sets each in this list to the corresponding elements in the array, as if by

 ListIterator iter = listIterator(index);
 long i = 0;
 while (i < length) {
   iter.next();
   iter.set(BigArrays.get(a, offset + i++);
