Constructor Detail

BaseProxyIntList

protected BaseProxyIntList()
Method Detail

getProxiedList

protected abstract IntList getProxiedList()

getProxiedCollection

protected final IntCollection getProxiedCollection()
Specified by:
getProxiedCollection in class BaseProxyIntCollection

add

public void add(int index,
                int element)
Description copied from interface: IntList
Inserts the specified element at the specified position (optional operation). Shifts the element currently at that position (if any) and any subsequent elements to the right, increasing their indices.

Specified by:
add in interface IntList
Parameters:
index - the index at which to insert the element
element - the value to insert

addAll

public boolean addAll(int index,
                      IntCollection collection)
Description copied from interface: IntList
Inserts all of the elements in the specified collection into me, at the specified position (optional operation). Shifts the element currently at that position (if any) and any subsequent elements to the right, increasing their indices. The new elements will appear in the order that they are returned by the given collection's iterator.

Specified by:
addAll in interface IntList
Parameters:
index - the index at which to insert the first element from the specified collection
collection - the IntCollection of elements to add
Returns:
true iff I changed as a result of this call

get

public int get(int index)
Description copied from interface: IntList
Returns the value of the element at the specified position within me.

Specified by:
get in interface IntList
Parameters:
index - the index of the element to return
Returns:
the value of the element at the specified position

indexOf

public int indexOf(int element)
Description copied from interface: IntList
Returns the index of the first occurrence of the specified element within me, or -1 if I do not contain the element.

Specified by:
indexOf in interface IntList
Parameters:
element - the element to search for
Returns:
the smallest index of an element matching the specified value, or -1 if no such matching element can be found

lastIndexOf

public int lastIndexOf(int element)
Description copied from interface: IntList
Returns the index of the last occurrence of the specified element within me, or -1 if I do not contain the element.

Specified by:
lastIndexOf in interface IntList
Parameters:
element - the element to search for
Returns:
the largest index of an element matching the specified value, or -1 if no such matching element can be found

listIterator

public IntListIterator listIterator()
Description copied from interface: IntList
Returns a bidirectional iterator over all my elements, in the appropriate sequence.

Specified by:
listIterator in interface IntList

listIterator

public IntListIterator listIterator(int index)
Description copied from interface: IntList
Returns a bidirectional iterator over all my elements, in the appropriate sequence, starting at the specified position. 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 IntList

removeElementAt

public int removeElementAt(int index)
Description copied from interface: IntList
Removes the element at the specified position in (optional operation). Any subsequent elements are shifted to the left, subtracting one from their indices. Returns the element that was removed.

Specified by:
removeElementAt in interface IntList
Parameters:
index - the index of the element to remove
Returns:
the value of the element that was removed

set

public int set(int index,
               int element)
Description copied from interface: IntList
Replaces the element at the specified position in me with the specified element (optional operation).

Specified by:
set in interface IntList
Parameters:
index - the index of the element to change
element - the value to be stored at the specified position
Returns:
the value previously stored at the specified position

subList

public IntList subList(int fromIndex,
                       int toIndex)
Description copied from interface: IntList
Returns a view of the elements within me between the specified fromIndex, inclusive, and toIndex, exclusive. The returned IntList is backed by me, so that any changes in the returned list are reflected in me, and vice-versa. The returned list supports all of the optional operations that I support.

Note that when fromIndex == toIndex, the returned list is initially empty, and when fromIndex == 0 && toIndex == size() the returned list is my "improper" sublist, containing all my elements.

The semantics of the returned list become undefined if I am structurally modified in any way other than via the returned list.

Specified by:
subList in interface IntList
Parameters:
fromIndex - the smallest index (inclusive) in me that appears in the returned list
toIndex - the largest index (exclusive) in me that appears in the returned list
Returns:
a view of this list from fromIndex (inclusive) to toIndex (exclusive)
