public class AVListImpl extends java.lang.Object implements AVList
An implementation class for theAVList
interface. Classes implementingAVList
can subclass or aggregate this class to provide defaultAVList
functionality. This class maintains a hash table of attribute-value pairs.This class implements a notification mechanism for attribute-value changes. The mechanism provides a means for objects to observe attribute changes or queries for certain keys without explicitly monitoring all keys. See
PropertyChangeSupport
.
