public abstract class AbstractLongIterator extends Object implements LongIterator
To create a type-specific iterator you need both a method returning the next element as primitive type and a method returning the next element as an object. However, if you inherit from this class you need just one (anyone).
This class implements also a trivial version of skip(int) that uses
type-specific methods; moreover, remove() will throw an UnsupportedOperationException.
Iterator| Modifier and Type | Method and Description |
|---|---|
Long |
next()
Delegates to the corresponding type-specific method.
|
long |
nextLong()
Delegates to the corresponding generic method.
|
void |
remove()
This method just throws an
UnsupportedOperationException. |
int |
skip(int n)
This method just iterates the type-specific version of
next() for at most
n times, stopping if Iterator.hasNext() becomes false. |
