Method Detail

hasPrevious

public boolean hasPrevious()

Description copied from interface: DoubleListIterator

Returns true iff I have more elements when traversed in the reverse direction. (In other words, returns true iff a call to DoubleListIterator.previous() will return an element rather than throwing an exception.

Specified by:

hasPrevious in interface DoubleListIterator

Returns:

true iff I have more elements when traversed in the reverse direction

nextIndex

public int nextIndex()

Description copied from interface: DoubleListIterator

Returns the index of the element that would be returned by a subsequent call to DoubleListIterator.next(), or the number of elements in my iteration if I have no next element.

Specified by:

nextIndex in interface DoubleListIterator

Returns:

the index of the next element in me

previous

public double previous()

Description copied from interface: DoubleListIterator

Returns the next element in me when traversed in the reverse direction.

Specified by:

previous in interface DoubleListIterator

Returns:

the previous element in me

previousIndex

public int previousIndex()

Description copied from interface: DoubleListIterator

Returns the index of the element that would be returned by a subsequent call to DoubleListIterator.previous(), or -1 if I have no previous element.

Specified by:

previousIndex in interface DoubleListIterator

Returns:

the index of the previous element in me

getIterator

protected final DoubleIterator getIterator()

Specified by:
