UnmodifiableListIterator

public UnmodifiableListIterator(DoubleListIterator i)

Method Detail

hasNext

public boolean hasNext()

Description copied from interface: java.util.Iterator

Returns true if the iteration has more elements. (In other words, returns true if Iterator.next() would return an element rather than throwing an exception.)

Specified by:

hasNext in interface Iterator<Double>

Specified by:

hasNext in interface ListIterator<Double>

Returns:

true if the iteration has more elements

hasPrevious

public boolean hasPrevious()

Description copied from interface: BidirectionalIterator

Returns whether there is a previous element.

Specified by:

hasPrevious in interface BidirectionalIterator<Double>

Specified by:

hasPrevious in interface ListIterator<Double>

Returns:

whether there is a previous element.

See Also:

ListIterator.hasPrevious()

nextDouble

public double nextDouble()

Description copied from interface: DoubleIterator

Returns the next element as a primitive type.

Specified by:

nextDouble in interface DoubleIterator

Specified by:

nextDouble in interface PrimitiveIterator.OfDouble

Returns:

the next element in the iteration.

See Also:

Iterator.next()

previousDouble

public double previousDouble()

Description copied from interface: DoubleBidirectionalIterator

Returns the previous element as a primitive type.

Specified by:

previousDouble in interface DoubleBidirectionalIterator

Returns:

the previous element in the iteration.

See Also:

ListIterator.previous()

nextIndex

public int nextIndex()

Description copied from interface: java.util.ListIterator

Returns the index of the element that would be returned by a subsequent call to ListIterator.next(). (Returns list size if the list iterator is at the end of the list.)

Specified by:

nextIndex in interface ListIterator<Double>

Returns:

the index of the element that would be returned by a subsequent call to next, or list size if the list iterator is at the end of the list

previousIndex

public int previousIndex()

Description copied from interface: java.util.ListIterator

Returns the index of the element that would be returned by a subsequent call to ListIterator.previous(). (Returns -1 if the list iterator is at the beginning of the list.)

Specified by:

previousIndex in interface ListIterator<Double>

Returns:

the index of the element that would be returned by a subsequent call to previous, or -1 if the list iterator is at the beginning of the list
