Constructor Detail

ConverterCollections.ConverterListIterator

public ConverterCollections.ConverterListIterator(java.util.ListIterator iter,
                                                  Converter convUp,
                                                  Converter convDown)

Constructor.

Parameters:

iter - the underlying ListIterator

convUp - the Converter from the underlying ListIterator

convDown - the Converter to the underlying 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 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()

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

Specified by:

next in interface java.util.Iterator

Specified by:

next in interface java.util.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 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()

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

Specified by:

previous in interface java.util.ListIterator

Returns:

the previous element in the list

Throws:

java.util.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 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()

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 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

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 java.util.Iterator

Specified by:

remove in interface java.util.ListIterator

set

public void set(java.lang.Object o)
