Class LongIterators.AbstractIndexBasedIterator

it.unimi.dsi.fastutil.longs.AbstractLongIterator
it.unimi.dsi.fastutil.longs.LongIterators.AbstractIndexBasedIterator
- All Implemented Interfaces:
LongIterator
,Iterator<Long>
,PrimitiveIterator<Long,
,LongConsumer> PrimitiveIterator.OfLong
- Direct Known Subclasses:
LongIterators.AbstractIndexBasedListIterator
- Enclosing class:
LongIterators
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 Details
-
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:
-
remove
public void remove() -
forEachRemaining
-
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()
forn
times (possibly stopping ifIterator.hasNext()
becomes false).- Parameters:
n
- the number of elements to skip.- Returns:
- the number of elements actually skipped.
