Class AbstractKFList<T>

java.lang.Object

com.microej.kf.util.AbstractKFList<T>

All Implemented Interfaces:

ej.kf.FeatureStateListener, java.lang.Iterable<T>, java.util.Collection<T>

Direct Known Subclasses:

KFList, KFList2

public abstract class AbstractKFList<T>
extends java.lang.Object
implements java.util.Collection<T>, ej.kf.FeatureStateListener

Implementation of a Collection with multi-context support.

This class can only be embedded in Kernel code. It cannot be embedded into Feature code.

This collection does not allow to pass null elements.

The semantic is the following:

• Each context has its dedicated list, acting as an ArrayList.
• A Feature can add Feature or Kernel objects to its list.
• The Kernel can only add Kernel objects to its list. However it has the full control and visibility on all the elements of the collection. For example, the call of the Collection.clear() method clears the whole collection. The call to Collection.iterator() method return an iterator on all objects of the collection...
