Method Summary

Modifier and Type	Method and Description
void	add(float value) Inserts the specified element into my underlying collection (optional operation).
protected FloatIterator	getIterator()
protected FloatListIterator	getListIterator()
boolean	hasNext() Returns true iff I have more elements.
boolean	hasPrevious() Returns true iff I have more elements when traversed in the reverse direction.
float	next() Returns the next element in me.
int	nextIndex() Returns the index of the element that would be returned by a subsequent call to FloatListIterator.next(), or the number of elements in my iteration if I have no next element.
float	previous() Returns the next element in me when traversed in the reverse direction.
int	previousIndex() Returns the index of the element that would be returned by a subsequent call to FloatListIterator.previous(), or -1 if I have no previous element.
void	remove() Removes from my underlying collection the last element returned by FloatListIterator.next() or FloatListIterator.previous() (optional operation).
void	set(float value) Replaces in my underlying collection the last element returned by FloatListIterator.next() or FloatListIterator.previous() with the specified value (optional operation).

Method Detail

remove

public void remove()

Description copied from interface: FloatListIterator

Removes from my underlying collection the last element returned by FloatListIterator.next() or FloatListIterator.previous() (optional operation).

add

public void add(float value)

Description copied from interface: FloatListIterator

Inserts the specified element into my underlying collection (optional operation). The element is inserted immediately before the next element that would have been returned by FloatListIterator.next(), if any, and immediately after the next element that would have been returned by FloatListIterator.previous(), if any.

The new element is inserted immediately before the implied cursor. A subsequent call to FloatListIterator.previous() will return the added element, a subsequent call to FloatListIterator.next() will be unaffected. This call increases by one the value that would be returned by a call to FloatListIterator.nextIndex() or FloatListIterator.previousIndex().

Parameters:

value - the value to be inserted

set

public void set(float value)

Description copied from interface: FloatListIterator

Replaces in my underlying collection the last element returned by FloatListIterator.next() or FloatListIterator.previous() with the specified value (optional operation).

Parameters:

value - the value to replace the last returned element with

getListIterator

protected FloatListIterator getListIterator()

wrap

public static final FloatListIterator wrap(FloatListIterator iterator)

hasPrevious

public boolean hasPrevious()

Description copied from interface: FloatListIterator

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

Specified by:

hasPrevious in interface FloatListIterator

Returns:

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

nextIndex

public int nextIndex()

Description copied from interface: FloatListIterator

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

Specified by:

nextIndex in interface FloatListIterator

Returns:

the index of the next element in me

previous

public float previous()

Description copied from interface: FloatListIterator

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

Specified by:

previous in interface FloatListIterator

Returns:

the previous element in me

previousIndex

public int previousIndex()

Description copied from interface: FloatListIterator

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

Specified by:

previousIndex in interface FloatListIterator

Returns:

the index of the previous element in me

getIterator

protected final FloatIterator getIterator()

hasNext

public boolean hasNext()

Description copied from interface: FloatIterator

Returns true iff I have more elements. (In other words, returns true iff a subsequent call to next will return an element rather than throwing an exception.)

Specified by:

hasNext in interface FloatIterator

Returns:

true iff I have more elements

next

public float next()

Description copied from interface: FloatIterator

Returns the next element in me.

Specified by:

next in interface FloatIterator

Returns:

the next element in me
