public abstract static class ShortIterators.AbstractIndexBasedIterator extends AbstractShortIterator
A skeletal implementation for an iterator backed by an index-based data store. High performance concrete implementations (like the main Iterator of ArrayList) generally should avoid using this and just implement the interface directly, but should be decent for less performance critical implementations.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 specificBigListIterators
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 Detail
-
hasNext
public boolean hasNext()
-
nextShort
public short nextShort()
Description copied from interface:ShortIterator
Returns the next element as a primitive type.- Returns:
- the next element in the iteration.
- See Also:
Iterator.next()
-
remove
public void remove()
-
forEachRemaining
public void forEachRemaining(ShortConsumer action)
Description copied from interface:ShortIterator
Performs the given action for each remaining element until all elements have been processed or the action throws an exception.- Parameters:
action
- the action to be performed for each element.- See Also:
Iterator.forEachRemaining(java.util.function.Consumer)
-
skip
public int skip(int n)
Description copied from interface:ShortIterator
Skips the given number of elements.The effect of this call is exactly the same as that of calling
ShortIterator.next()
forn
times (possibly stopping ifIterator.hasNext()
becomes false).- Parameters:
n
- the number of elements to skip.- Returns:
- the number of elements actually skipped.
- See Also:
Iterator.next()
