Field Detail

m_iter

protected ListIterator m_iter

The underlying ListIterator.

m_clz

protected Class m_clz

The class of Objects stored in the ListIterator.

Constructor Detail

RestrictedListIterator

public RestrictedListIterator(ListIterator iter,
                              Class clz)

Constructor.

Parameters:

iter - the underlying ListIterator

clz - the class of objects that may be stored in the ListIterator

Method Detail

hasNext

public boolean hasNext()

Returns true if this list iterator has more elements when traversing the list in the forward direction. Obeys the general contract of ListIterator.hasNext.

Specified by:

hasNext in interface Iterator

Specified by:

hasNext in interface ListIterator

Returns:

true if the list iterator has more elements when traversing the list in the forward direction

next

public Object next()

Returns the next element in the list. Obeys the general contract of ListIterator.next.

Specified by:

next in interface Iterator

Specified by:

next in interface ListIterator

Returns:

the next element in the list

hasPrevious

public boolean hasPrevious()

Returns true if this list iterator has more elements when traversing the list in the reverse direction. Obeys the general contract of ListIterator.hasPrevious.

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()

Returns the previous element in the list. Obeys the general contract of ListIterator.previous.

Specified by:

previous in interface ListIterator

Returns:

the previous element in the list

Throws:

NoSuchElementException - if the iteration has no previous element

nextIndex

public int nextIndex()

Returns the index of the element that would be returned by a subsequent call to next. Obeys the general contract of ListIterator.nextIndex.

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()

Returns the index of the element that would be returned by a subsequent call to previous. Obeys the general contract of ListIterator.previousIndex.

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

remove

public void remove()

Removes from the list the last element that was returned by next or previous. Obeys the general contract of ListIterator.remove.

Specified by:

remove in interface Iterator

Specified by:

remove in interface ListIterator

set

public void set(Object o)

Replaces the last element returned by next or previous with the specified element. Obeys the general contract of ListIterator.set.

Specified by:

set in interface ListIterator

Parameters:

o - the element with which to replace the last element returned by next or previous

Throws:

ClassCastException - if the class of the specified element prevents it from being added to this list

add

public void add(Object o)

Inserts the specified element into the list. Obeys the general contract of ListIterator.add.

Specified by:

add in interface ListIterator

Parameters:

o - the element to insert

Throws:

ClassCastException - if the class of the specified element prevents it from being added to this ListIterator

checkObject
