- Enclosing class:
DoubleIterators
This class is only appropriate for sequences that are at most Integer.MAX_VALUE
long. If
your backing data store can be bigger then this, consider the equivalently named class in the
type specific BigListSpliterators
class.
As the abstract methods in this class are used in inner loops, it is generally a good idea to
override the class as final
as to encourage the JVM to inline them (or alternatively,
override the abstract methods as final).

Method Details
-
hasPrevious
public boolean hasPrevious()Description copied from interface:BidirectionalIterator
Returns whether there is a previous element.- Specified by:
hasPrevious
in interfaceBidirectionalIterator<Double>
- Specified by:
hasPrevious
in interfaceListIterator<Double>
- Returns:
- whether there is a previous element.
- See Also:
-
previousDouble
public double previousDouble()Description copied from interface:DoubleBidirectionalIterator
Returns the previous element as a primitive type.- Specified by:
previousDouble
in interfaceDoubleBidirectionalIterator
- Returns:
- the previous element in the iteration.
- See Also:
-
nextIndex
public int nextIndex()- Specified by:
nextIndex
in interfaceListIterator<Double>
-
previousIndex
public int previousIndex()- Specified by:
previousIndex
in interfaceListIterator<Double>
-
add
public void add(double k) Description copied from interface:DoubleListIterator
Inserts the specified element into the list (optional operation).This default implementation just throws an
UnsupportedOperationException
.- Specified by:
add
in interfaceDoubleListIterator
- Parameters:
k
- the element to insert.- See Also:
-
set
public void set(double k) Description copied from interface:DoubleListIterator
Replaces the last element returned byDoubleListIterator.next()
orDoubleListIterator.previous()
with the specified element (optional operation).- Specified by:
set
in interfaceDoubleListIterator
- Parameters:
k
- the element used to replace the last element returned.This default implementation just throws an
UnsupportedOperationException
.- See Also:
-
back
public int back(int n) Description copied from interface:DoubleBidirectionalIterator
Moves back for the given number of elements.The effect of this call is exactly the same as that of calling
DoubleBidirectionalIterator.previous()
forn
times (possibly stopping ifBidirectionalIterator.hasPrevious()
becomes false).- Specified by:
back
in interfaceDoubleBidirectionalIterator
- Specified by:
back
in interfaceObjectBidirectionalIterator<Double>
- Parameters:
n
- the number of elements to skip back.- Returns:
- the number of elements actually skipped.
