@Deprecated
public class BbDeleteTrackingList
extends BbList

An extension of BbList that maintains a tracking set of elements that have been removed through one mechanism or another. Useful within the persistence framework to track child objects attached to heavyweight objects, and delete them as needed.

For instance, imagine a class Foo, containing an array of Bar objects. When a Foo instance is loaded, and then one of the Bar elements is removed from its list, it would be difficult to update the database to reflect the deletion of that object. Now, however, a call to getDeletedElements() returns a complete set of elements unlinked one way or another.

Note: This class is typically for Blackboard-only use and should be considered unstable.

Since:

Bb 6.0

Constructor Detail

BbDeleteTrackingList

public BbDeleteTrackingList()

Deprecated.

Default Constructor. Constructs a list that does not enforce type safety and can accept any type of object as a member.

BbDeleteTrackingList

public BbDeleteTrackingList(java.lang.Class typeClass)

Deprecated.

Constructs a BbList designated to only accept objects that are instances of the object represented by the provided Class value for addition to the list. Any attempt to add objects of a different type will result in an exception being thrown. An example declaration of a BbList designed to only contain object of type Integer:

 BbList list = new BbList( Integer.class );
 list.add( Integer.valueOf( 1 ) );  <-- successful
 list.add( new Float( 1.0 ) );  <-- throws IllegalArgumentException
 

Parameters:

typeClass - An instance of Class that represents the type of object that can be added to the list

Method Detail

add

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

Deprecated.

Inserts the specified element at the specified position in this list. Ensures that equivalent objects are removed from the tracking set.

Specified by:

add in interface java.util.List

Overrides:

add in class BbList

Parameters:

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

element - The element to be inserted

Throws:

java.lang.IndexOutOfBoundsException - If the index is out of range (index < 0 || index > size())

add

public boolean add(java.lang.Object o)

Deprecated.

Appends the specified element to this list. Ensures that equivalent objects are removed from the tracking list.

Specified by:

add in interface java.util.Collection

Specified by:

add in interface java.util.List

Overrides:

add in class BbList

Parameters:

o - The object to be added

Returns:

true As per the general contract of Collection.add

addAll

public boolean addAll(java.util.Collection c)

Deprecated.

Appends all of the elements in the specified Collection to the end of this list, in the order that they are returned by the specified Collection's Iterator. The behavior of this operation is undefined if the specified Collection is modified while the operation is in progress. (This implies that the behavior of this call is undefined if the specified Collection is this list, and this list is nonempty.) Ensures that equivalent objects are removed from the tracking list.

Specified by:

addAll in interface java.util.Collection

Specified by:

addAll in interface java.util.List

Overrides:

addAll in class java.util.ArrayList

Parameters:

c - The collection to be added

Returns:

true As per the general contract of Collection.addAll

addAll

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

Deprecated.

Inserts all of the elements in the specified Collection to the end of this list, in the order that they are returned by the specified Collection's Iterator. The behavior of this operation is undefined if the specified Collection is modified while the operation is in progress. (This implies that the behavior of this call is undefined if the specified Collection is this list, and this list is nonempty.) Ensures that equivalent objects are removed from the tracking list.

Specified by:

addAll in interface java.util.List

Overrides:

addAll in class java.util.ArrayList

Parameters:

index - The index at which the specified collection is to be inserted

c - The collection to be added

Returns:

true As per the general contract of Collection.addAll

Throws:

java.lang.IndexOutOfBoundsException - If the index is out of range (index < 0 || index > size())

clear

public void clear()

Deprecated.

Removes all of the elements from this list. The list will be empty after this call returns. Copies all elements into the tracking list that are not already there.

Specified by:

clear in interface java.util.Collection

Specified by:

clear in interface java.util.List

Overrides:

clear in class java.util.ArrayList

remove

public java.lang.Object remove(int index)

Specified by:

remove in interface java.util.List

Overrides:

remove in class java.util.ArrayList

Parameters:

index - The index of the element to be removed

Returns:

The element that was removed from the list

Throws:

java.lang.IndexOutOfBoundsException - If the index is out of range (index < 0 || index > size())

remove

public boolean remove(java.lang.Object o)

Deprecated.

Removes a single instance of the specified element from this collection, if it is present. Copies the object into the tracking list if it is not already there.

Specified by:

remove in interface java.util.Collection

Specified by:

remove in interface java.util.List

Overrides:

remove in class java.util.ArrayList

removeAll in interface java.util.List

Overrides:

removeAll in class java.util.AbstractCollection

Parameters:

c - The collection that defines which elements will be removed

Returns:

true If the list changes as a result of the call

retainAll

public boolean retainAll(java.util.Collection c)

Deprecated.

Retains only the elements in this list that are not contained in the specified collection. Copies each element not retained into the tracking list if it is not already there.
