Constructor Detail

ImmutableKeyList

protected ImmutableKeyList(KeyList<E> that)

Private constructor used internally.

Parameters:

that - list to create an immutable view of

Method Detail

doEnsureCapacity

protected void doEnsureCapacity(int capacity)

Description copied from class: IList

Increases the capacity of this list instance, if necessary, to ensure that it can hold at least the number of elements specified by the minimum capacity argument.

Overrides:

doEnsureCapacity in class KeyListImpl<E>

Parameters:

capacity - the desired minimum capacity

doAdd

protected boolean doAdd(int index,
                        E elem)

Description copied from class: IList

Helper method for adding an element to the list. This is the only method which really adds an element. Override if you need to validity checks before adding.

Overrides:

doAdd in class KeyListImpl<E>

Parameters:

index - index where element should be added (-1 means it is up to the implementation to choose the index)

elem - element to add

Returns:

true if element has been added, false otherwise

doSet

protected E doSet(int index,
                  E elem)

Description copied from class: IList

Helper method for setting an element in the list. This is the only method which really sets an element. Override if you need to validity checks before setting.

Overrides:

doSet in class KeyListImpl<E>

Parameters:

index - index where element will be placed

elem - element to set

Returns:

old element which was at the position

doReSet

protected E doReSet(int index,
                    E elem)

Description copied from class: IList

Sets an element at specified position. This method is used internally if existing elements will be moved etc. Override if you need to validity checks.

Overrides:

doReSet in class KeyListImpl<E>

Parameters:

index - index where element will be placed

elem - element to set

Returns:

old element which was at the position

doRemove

protected E doRemove(int index)

Description copied from class: IList

Helper method to remove an element. This is the only method which really removes an element. Override if you need to validity checks before removing.

Overrides:

doRemove in class KeyListImpl<E>

Parameters:

index - index of element to remove

Returns:

removed element

doRemoveAll

protected void doRemoveAll(int index,
                           int len)

Description copied from class: IList

Remove specified range of elements from list.

Overrides:

doRemoveAll in class KeyListImpl<E>

Parameters:

index - index of first element to remove

len - number of elements to remove

doClear

protected void doClear()

Overrides:

doClear in class IList<E>

doModify

protected void doModify()

Description copied from class: IList

This method is called internally before elements are allocated or freed. Override if you need to validity checks.

Overrides:

doModify in class IList<E>

removeByKey

protected E removeByKey(int keyIndex,
                        java.lang.Object key)

Description copied from class: KeyListImpl

Removes element by key. If there are duplicates, only one element is removed.

Overrides:

removeByKey in class KeyListImpl<E>

Parameters:

keyIndex - key index

key - key of element to remove

Returns:

removed element or null if no element has been removed

removeAllByKey

protected IList<E> removeAllByKey(int keyIndex,
                                  java.lang.Object key)

Description copied from class: KeyListImpl

Removes element by key. If there are duplicates, all elements are removed.

Overrides:

removeAllByKey in class KeyListImpl<E>

Parameters:

keyIndex - key index

key - key of element to remove

Returns:

true if elements have been removed, false otherwise

putByKey

protected E putByKey(int keyIndex,
                     E elem,
                     boolean replace)

Description copied from class: KeyListImpl

Put element by key into list.

Overrides:

putByKey in class KeyListImpl<E>

Parameters:

keyIndex - key index

elem - element to put

replace - true to replace an existing element with the same key, false to let the element unchanged

Returns:

element with the same key (i.e. element which was replaced if replace is true / which was left unchanged if false), null if no element with the same key has been found

invalidateKey

protected void invalidateKey(int keyIndex,
                             java.lang.Object oldKey,
                             java.lang.Object newKey,
                             E elem)

Description copied from class: KeyListImpl

Invalidate key value of element. You must call an invalidate method if an element's key value has changed after adding it to the collection.

Overrides:

invalidateKey in class KeyListImpl<E>

Parameters:

keyIndex - key index

oldKey - old key value

newKey - new key value

elem - element to invalidate (can be null if there are no duplicates with this key)

error

private void error()

Throw exception if an attempt is made to change an immutable list.
