Constructor Detail

AppendListIterator

public AppendListIterator(java.util.ListIterator iter1,
                          java.util.ListIterator iter2)

Creates new AppendListIterator

Method Detail

hasPrevious

public boolean hasPrevious()

Description copied from interface: java.util.ListIterator

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 java.util.ListIterator

---

hasNext

public boolean hasNext()

Description copied from interface: java.util.ListIterator

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 java.util.ListIterator

---

previous

public java.lang.Object previous()

Description copied from interface: java.util.ListIterator

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 java.util.ListIterator

---

next

public java.lang.Object next()

Description copied from interface: java.util.ListIterator

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 java.util.ListIterator

---

previousIndex

public int previousIndex()

Description copied from interface: java.util.ListIterator

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 java.util.ListIterator

---

nextIndex

public int nextIndex()

Description copied from interface: java.util.ListIterator

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 java.util.ListIterator

---

remove

public void remove()

Description copied from interface: java.util.ListIterator

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 java.util.ListIterator

---

set

public void set(java.lang.Object o)

Description copied from interface: java.util.ListIterator

Replace the element last returned by a call to next or previous with a given object (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:

set in interface java.util.ListIterator

---

add

public void add(java.lang.Object o)

Description copied from interface: java.util.ListIterator

Insert an element into the list at the current position of the iterator (optional operation). The element is inserted in between the element that would be returned by previous and the element that would be returned by next. After the insertion, a subsequent call to next is unaffected, but a call to previous returns the item that was added. The values returned by nextIndex() and previousIndex() are incremented.

Specified by:

add in interface java.util.ListIterator
