java.lang.Object org.joda.primitives.listiterator.impl.ArrayBooleanListIterator
public class ArrayBooleanListIterator
An iterator over an array of boolean
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.

public ArrayBooleanListIterator(boolean[] array)
boolean
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

public static ArrayBooleanListIterator copyOf(boolean[] array)
boolean
values.
The specified array is copied, ensuring the original data is unaltered.
Note that the class is not immutable due to the set
methods.
