                                          Converter convDown)

Constructor.

Parameters:

list - the underlying List

convUp - the Converter from the underlying List

convDown - the Converter to the underlying List

Method Detail

get

public java.lang.Object get(int index)

Returns the element at the specified position in this list.

Specified by:

get in interface java.util.List

Parameters:

index - index of element to return

Returns:

the element at the specified position in this list

set

public java.lang.Object set(int index,
                            java.lang.Object element)

Replaces the element at the specified position in this list with the specified element (optional operation).

Specified by:

set in interface java.util.List

Parameters:

index - index of element to replace.

element - element to be stored at the specified position.

Returns:

the element previously at the specified position.

add

public void add(int index,
                java.lang.Object element)

Inserts the specified element at the specified position in this list (optional operation). Shifts the element currently at that position (if any) and any subsequent elements to the right (adds one to their indices).

Specified by:

add in interface java.util.List

Parameters:

index - index at which the specified element is to be inserted

element - element to be inserted

addAll

public boolean addAll(int index,
                      java.util.Collection col)

Inserts all of the elements in the specified collection into this list at the specified position (optional operation).

Specified by:

addAll in interface java.util.List

Parameters:

index - index at which to insert first element from the specified collection

col - elements to be inserted into this list

Returns:

true if this list changed as a result of the call

remove

public java.lang.Object remove(int index)

Removes the element at the specified position in this list (optional operation). Shifts any subsequent elements to the left (subtracts one from their indices). Returns the element that was removed from the list.

Specified by:

remove in interface java.util.List

Parameters:

index - the index of the element to removed

Returns:

the element previously at the specified position

indexOf

public int indexOf(java.lang.Object o)

Returns the index in this list of the first occurrence of the specified element, or -1 if this list does not contain this element. More formally, returns the lowest index i such that (o==null ? get(i)==null : o.equals(get(i))), or -1 if there is no such index.

Specified by:

indexOf in interface java.util.List

Parameters:

o - element to search for

Returns:

the index in this list of the first occurrence of the specified element, or -1 if this list does not contain this element

lastIndexOf

public int lastIndexOf(java.lang.Object o)

Returns the index in this list of the last occurrence of the specified element, or -1 if this list does not contain this element. More formally, returns the highest index i such that (o==null ? get(i)==null : o.equals(get(i))), or -1 if there is no such index.

Specified by:

lastIndexOf in interface java.util.List

Parameters:

o - element to search for

Returns:

the index in this list of the last occurrence of the specified element, or -1 if this list does not contain this element.

listIterator

public java.util.ListIterator listIterator()

Returns a list iterator of the elements in this list (in proper sequence).

Specified by:

listIterator in interface java.util.List

Returns:

a list iterator of the elements in this list (in proper sequence)

listIterator

public java.util.ListIterator listIterator(int index)

Returns a list iterator of the elements in this list (in proper sequence), starting at the specified position in this list. The specified index indicates the first element that would be returned by an initial call to the next method. An initial call to the previous method would return the element with the specified index minus one.

Specified by:

listIterator in interface java.util.List

Parameters:

index - index of first element to be returned from the list iterator (by a call to the next method)

Returns:

a list iterator of the elements in this list (in proper sequence), starting at the specified position in this list

subList

public java.util.List subList(int fromIndex,
                              int toIndex)

Returns a view of the portion of this list between the specified fromIndex, inclusive, and toIndex, exclusive. Obeys the general contract of List.subList.

Specified by:

subList in interface java.util.List

Parameters:

fromIndex - low endpoint (inclusive) of the subList

toIndex - high endpoint (exclusive) of the subList

Returns:

a view of the specified range within this list

equals

public boolean equals(java.lang.Object o)

Compares the specified object with this collection for equality.

Obeys the general contract of Collection.equals.

Specified by:

equals in interface java.util.Collection

Specified by:

equals in interface java.util.List

Overrides:

equals in class ConverterCollections.ConverterCollection

Parameters:

o - Object to be compared for equality with this Collection

Returns:

true if the specified object is equal to this Collection

See Also:

Object.equals(Object), Set.equals(Object), List.equals(Object)

hashCode

public int hashCode()

Returns the hash code value for this list. The hash code of a list is defined to be the result of the following calculation:

  hashCode = 1;
  Iterator i = list.iterator();
  while (i.hasNext()) {
      Object obj = i.next();
      hashCode = 31*hashCode + (obj==null ? 0 : obj.hashCode());
  }
 

This ensures that list1.equals(list2) implies that list1.hashCode()==list2.hashCode() for any two lists, list1 and list2, as required by the general contract of Object.hashCode.

Specified by:

hashCode in interface java.util.Collection

Specified by:

hashCode in interface java.util.List

Returns:

the hash code value for this list.

See Also:

Object.hashCode(), Object.equals(Object), List.equals(Object)

                                         Converter convUp,
                                         Converter convDown)

Create a Converter List.

Parameters:

list - the underlying List

convUp - the Converter to view the underlying List through

convDown - the Converter to pass items down to the underlying List through

Returns:

a Converter List

instantiateListIterator

protected java.util.ListIterator instantiateListIterator(java.util.ListIterator iter,
                                                         Converter convUp,
                                                         Converter convDown)

Create a Converter ListIterator.

Parameters:

iter - the underlying ListIterator

convUp - the Converter to view the underlying ListIterator through

convDown - the Converter to pass items down to the underlying ListIterator through

Returns:

a Converter ListIterator

getList

public java.util.List getList()

Return the underlying List.
