Constructor Detail

RestrictedCollections.RestrictedList

public RestrictedCollections.RestrictedList(List list,
                                            Class clz)

Constructor.

Parameters:

list - the underlying List

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

Method Detail

get

public Object get(int index)

Returns the element at the specified position in this list.

Specified by:

get in interface List

Parameters:

index - index of element to return

Returns:

the element at the specified position in this list

set

public Object set(int index,
                  Object element)

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

Specified by:

set in interface 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.

Throws:

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

add

public void add(int index,
                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 List

Parameters:

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

element - element to be inserted

Throws:

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

addAll

public boolean addAll(int index,
                      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 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

Throws:

ClassCastException - if the class of one of elements of the specified collection prevents it from being added to this list

remove

public 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 List

Parameters:

index - the index of the element to removed

Returns:

the element previously at the specified position

indexOf

public int indexOf(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 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(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 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 ListIterator listIterator()

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

Specified by:

listIterator in interface List

Returns:

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

listIterator

public 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 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 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 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
