Method Summary |
void |
add(java.lang.Object o)
Inserts the specified element into the list (optional operation). |
boolean |
hasNext()
Returns true if this list iterator has more elements when traversing the list in the forward direction. |
boolean |
hasPrevious()
Returns true if this list iterator has more elements when traversing the list in the reverse direction. |
java.lang.Object |
next()
Returns the next element in the list. |
int |
nextIndex()
Returns the index of the element that would be returned by a subsequent call to next. |
java.lang.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 list the last element that was returned by next or previous (optional operation). |
void |
set(java.lang.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.ListIterator
- Removes from the list the last element that was returned by next or previous (optional operation). This call can only be made once per call to next or previous. It can be made only if ListIterator.add has not been called after the last call to next or previous.

remove

add
public void add(java.lang.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 java.util.ListIterator
-
- Parameters:
o
- the element to insert.
set
public void set(java.lang.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 java.util.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.ListIterator
- Returns true if this list iterator has more elements when traversing the list in the forward direction. (In other words, returns true if next would return an element rather than throwing an exception.)
-
- Specified by:
hasNext
in interface java.util.Iterator
- Specified by:
hasNext
in interface java.util.ListIterator
-
- Returns:
- true if the list iterator has more elements when traversing the list in the forward direction.
next
public java.lang.Object next()
- Description copied from interface:
java.util.ListIterator
- Returns the next element in the list. This method may be called repeatedly to iterate through the list, or intermixed with calls to previous to go back and forth. (Note that alternating calls to next and previous will return the same element repeatedly.)
-
- Specified by:
next
in interface java.util.Iterator
- Specified by:
next
in interface java.util.ListIterator
-
- Returns:
- the next element in the list.
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 java.util.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 java.util.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 java.util.ListIterator
-
- Returns:
- true if the list iterator has more elements when traversing the list in the reverse direction.
previous
public java.lang.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 java.util.ListIterator
-
- Returns:
- the previous element in the list.
