Interface Item

All Superinterfaces:: ContentSource, Handler, Invokable, Propertied, Referrer, java.io.Serializable, Typed, UContained

All Known Subinterfaces:: JAFable, View

All Known Implementing Classes:: ItemImpl, ViewImpl

public interface Item
extends UContained, Propertied, Invokable, Referrer, Typed, java.io.Serializable, Handler, ContentSource

A generic interface for an item in a view, describing its properties and actions. Think icon in a file-manager as a starting point, but it could be a database table, a row in a database, a jini service, an element in a vector or hashtable, a live object, an email message, etc. etc.

A Item may also implement View, in which case we get a nice tree structure e.g. filesystem directories

By default it is Serializable - this first came up as an issue when implementing drag'n'drop in the ui/gui viewer, but seems like a good thing to do anyway, given the network-centric nature of the whole project

refactored to use UField/Umethod April 2002
refactored to delegate to various aspect-oriented interfaces Jan 2003
