public class ArrayLongListIterator extends java.lang.Object implements LongListIterator
long
values.
This class implements ListIterator
allowing
seamless integration with other APIs.
The iterator can be reset to the start if required.
add()
and remove()
are unsupported, but
set()
is supported.

long
values.
The array is assigned internally, thus the caller holds a reference to the internal state of the returned iterator. It is not recommended to modify the state of the array after construction.
array
- the array to iterate over, must not be nulljava.lang.IllegalArgumentException
- if the array is nullpublic static ArrayLongListIterator copyOf(long[] array)
long
values.
The specified array is copied, ensuring the original data is unaltered.
Note that the class is not immutable due to the set
methods.
