LongIterators.AbstractIndexBasedIterator (fastutil 8.5.15)

java.lang.Object
- it.unimi.dsi.fastutil.longs.AbstractLongIterator
- - it.unimi.dsi.fastutil.longs.LongIterators.AbstractIndexBasedIterator

All Implemented Interfaces:

LongIterator, java.util.Iterator<java.lang.Long>, java.util.PrimitiveIterator<java.lang.Long,java.util.function.LongConsumer>, java.util.PrimitiveIterator.OfLong

Direct Known Subclasses:

LongIterators.AbstractIndexBasedListIterator

Enclosing class:

LongIterators
```
public abstract static class LongIterators.AbstractIndexBasedIterator
extends AbstractLongIterator
```
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 specific BigListIterators 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()
```
  - nextLong
```
public long nextLong()
```
    Description copied from interface: LongIterator
    
    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(java.util.function.LongConsumer action)
```
  - skip
```
public int skip(int n)
```
    Description copied from interface: LongIterator
    
    Skips the given number of elements.
    The effect of this call is exactly the same as that of calling LongIterator.next() for n times (possibly stopping if Iterator.hasNext() becomes false).
    
    Parameters:
    
    n - the number of elements to skip.
    
    Returns:
    
    the number of elements actually skipped.
