-
protected class ImmutableMultiList.MultiIterator
- extends Object
- implements ListIterator
ListIterator implementation based on the ImmutableMultiList.
Method Summary |
void |
add(Object o)
Inserts the specified element into the list (optional operation). |
boolean |
hasNext()
Returns true if the iteration has more elements. |
boolean |
hasPrevious()
Returns true if this list iterator has more elements when traversing the list in the reverse direction. |
Object |
next()
Returns the next element in the iteration. |
int |
nextIndex()
Returns the index of the element that would be returned by a subsequent call to next. |
Object |
previous()
Returns the previous element in the list. |
int |
previousIndex()
Returns the index of the element that would be returned by a subsequent call to previous. |
void |
remove()
Removes from the underlying collection the last element returned by the iterator (optional operation). |
void |
set(Object o)
Replaces the last element returned by next or previous with the specified element (optional operation). |
ImmutableMultiList.MultiIterator
public ImmutableMultiList.MultiIterator(int i)
remove
public void remove()
- Description copied from interface:
java.util.Iterator
- Removes from the underlying collection the last element returned by the iterator (optional operation). This method can be called only once per call to next. The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method.

remove

in interface ListIterator
add
public void add(Object o)
- Description copied from interface:
java.util.ListIterator
- Inserts the specified element into the list (optional operation). The element is inserted immediately before the next element that would be returned by next, if any, and after the next element that would be returned by previous, if any. (If the list contains no elements, the new element becomes the sole element on the list.) The new element is inserted before the implicit cursor: a subsequent call to next would be unaffected, and a subsequent call to previous would return the new element. (This call increases by one the value that would be returned by a call to nextIndex or previousIndex.)
-
- Specified by:
add
in interface ListIterator
-
- Parameters:
o
- the element to insert.
set
public void set(Object o)
- Description copied from interface:
java.util.ListIterator
- Replaces the last element returned by next or previous with the specified element (optional operation). This call can be made only if neither ListIterator.remove nor ListIterator.add have been called after the last call to next or previous.
-
- Specified by:
set
in interface ListIterator
-
- Parameters:
o
- the element with which to replace the last element returned by next or previous.
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 next would return an element rather than throwing an exception.)
-
- Specified by:
hasNext
in interface Iterator
- Specified by:
hasNext
in interface ListIterator
-
- Returns:
- true if the iterator has more elements.
next
public Object next()
- Description copied from interface:
java.util.Iterator
- Returns the next element in the iteration. Calling this method repeatedly until the
Iterator.hasNext()
method returns false will return each element in the underlying collection exactly once.
-
- Specified by:
next
in interface Iterator
- Specified by:
next
in interface ListIterator
-
- Returns:
- the next element in the iteration.
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 next. (Returns list size if the list iterator is at the end of the list.)
-
- Specified by:
nextIndex
in interface ListIterator
-
- Returns:
- the index of the element that would be returned by a subsequent call to next, or list size if list iterator is at end of 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 previous. (Returns -1 if the list iterator is at the beginning of the list.)
-
- Specified by:
previousIndex
in interface ListIterator
-
- Returns:
- the index of the element that would be returned by a subsequent call to previous, or -1 if list iterator is at beginning of list.
hasPrevious
public boolean hasPrevious()
- Description copied from interface:
java.util.ListIterator
- Returns true if this list iterator has more elements when traversing the list in the reverse direction. (In other words, returns true if previous would return an element rather than throwing an exception.)
-
- Specified by:
hasPrevious
in interface ListIterator
-
- Returns:
- true if the list iterator has more elements when traversing the list in the reverse direction.
previous
public Object previous()
- Description copied from interface:
java.util.ListIterator
- Returns the previous element in the list. This method may be called repeatedly to iterate through the list backwards, or intermixed with calls to next to go back and forth. (Note that alternating calls to next and previous will return the same element repeatedly.)
-
- Specified by:
previous
in interface ListIterator
-
- Returns:
- the previous element in the list.
