Constructor Details

ExtensionsIterator

public ExtensionsIterator()
The basic constructor. Object is special, because it has no superclass, so there is no call to super().

Method Details

add

public void add(Extension e)

hasNext

public boolean hasNext()
Tests whether there are elements remaining in the list in the forward direction. In other words, next() will not fail with a NoSuchElementException.
Specified by:
hasNext in interface ListIterator<E>
hasNext in interface Iterator<E>
Returns:
true if the list continues in the forward direction

hasPrevious

public boolean hasPrevious()
Tests whether there are elements remaining in the list in the reverse direction. In other words, previous() will not fail with a NoSuchElementException.
Specified by:
hasPrevious in interface ListIterator<E>
Returns:
true if the list continues in the reverse direction

next

public Extension next()
            throws NoSuchElementException
Obtain the next element in the list in the forward direction. Repeated calls to next may be used to iterate over the entire list, or calls to next and previous may be used together to go forwards and backwards. Alternating calls to next and previous will return the same element.
Specified by:
next in interface ListIterator<E>
next in interface Iterator<E>
Returns:
the next element in the list in the forward direction
Throws:
NoSuchElementException - if there are no more elements

nextIndex

public int nextIndex()
Find the index of the element that would be returned by a call to next. If hasNext() returns false, this returns the list size.
Specified by:
nextIndex in interface ListIterator<E>
Returns:
the index of the element that would be returned by next()

previous

public Extension previous()
            throws NoSuchElementException
Obtain the next element in the list in the reverse direction. Repeated calls to previous may be used to iterate backwards over the entire list, or calls to next and previous may be used together to go forwards and backwards. Alternating calls to next and previous will return the same element.
Specified by:
previous in interface ListIterator<E>
Returns:
the next element in the list in the reverse direction
Throws:
NoSuchElementException - if there are no more elements

previousIndex

public int previousIndex()
Find the index of the element that would be returned by a call to previous. If hasPrevious() returns false, this returns -1.
Specified by:
previousIndex in interface ListIterator<E>
Returns:
the index of the element that would be returned by previous()

remove

public void remove()
Remove from the list the element last returned by a call to next or previous (optional operation). This method may only be called if neither add nor remove have been called since the last call to next or previous.
Specified by:
remove in interface ListIterator<E>
remove in interface Iterator<E>
Throws:
IllegalStateException - if neither next or previous have been called, or if add or remove has been called since the last call to next or previous
UnsupportedOperationException - if this ListIterator does not support the remove operation

set

public void set(Extension e)
