public class ArrayDoubleIterator extends Object implements DoubleIterator
double
values.
This class implements Iterator
allowing
seamless integration with other APIs.
The iterator can be reset to the start if required.
It is unmodifiable and remove()
is unsupported.

public ArrayDoubleIterator(double[] array)
double
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.

double
values.
The specified array is copied, making this class effectively immutable.
Note that the class is not final
thus it is not truly immutable.
