LongBigListIterators
public abstract static class LongBigListIterators.AbstractIndexBasedBigListIterator
extends LongBigListIterators.AbstractIndexBasedBigIterator
implements LongBigListIterator
A skeletal implementation for a list-iterator backed by an index based data store. High
performance concrete implementations (like the main ListIterator of ArrayList) generally should
avoid using this and just implement the interface directly, but should be decent for less
performance critical implementations.
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<Long>
- Returns:
- whether there is a previous element.
- See Also:
-
previousLong
public long previousLong()Description copied from interface:LongBidirectionalIterator
Returns the previous element as a primitive type.- Specified by:
previousLong
in interfaceLongBidirectionalIterator
- Returns:
- the previous element in the iteration.
- See Also:
-
nextIndex
public long nextIndex()Description copied from interface:BigListIterator
Returns the index of the element that would be returned by a subsequent call to next. (Returns list size if the list iterator is at the end of the list.)- Specified by:
nextIndex
in interfaceBigListIterator<Long>
- Returns:
- the index of the element that would be returned by a subsequent call to next, or list size if list iterator is at end of list.
- See Also:
-
previousIndex
public long previousIndex()Description copied from interface:BigListIterator
Returns the index of the element that would be returned by a subsequent call to previous. (Returns -1 if the list iterator is at the beginning of the list.)- Specified by:
previousIndex
in interfaceBigListIterator<Long>
- Returns:
- the index of the element that would be returned by a subsequent call to previous, or -1 if list iterator is at beginning of list.
- See Also:
-
add
public void add(long k) Description copied from interface:LongBigListIterator
Inserts the specified element into the list (optional operation).- Specified by:
add
in interfaceLongBigListIterator
- See Also:
-
set
public void set(long k) Description copied from interface:LongBigListIterator
Replaces the last element returned bynext()
orprevious()
with the specified element (optional operation).- Specified by:
set
in interfaceLongBigListIterator
- See Also:
-
back
public long back(long n) Description copied from interface:LongBigListIterator
Moves back for the given number of elements.The effect of this call is exactly the same as that of calling
previous()
forn
times (possibly stopping ifBidirectionalIterator.hasPrevious()
becomes false).- Specified by:
back
in interfaceLongBigListIterator
- Parameters:
n
- the number of elements to skip back.- Returns:
- the number of elements actually skipped.
