bridges.dl_element.DLelement Class Reference

Inheritance diagram for bridges.dl_element.DLelement:

Detailed Description

This class is used to create doubly linked element objects.

Author

Mihai Mehedint, Kalpathi Subramanian

This class extends Element and takes a generic parameter <E> representing
application specific data. This element forms the basic building block for
doubly linked lists. Doubly linked elements have two links,
"next" and "previous", that point to the previous and succeeding nodes along the list.

Elements contain a visualizer (ElementVisualizer) object for setting visual
attributes (color, shape, opacity, size), necessary for displaying them in a web
browser.

Elements also have a LinkVisualizer object that is used when they are linked to
another element, appropriate for setting link attributes, such as in linked lists,
between the current element and its next or previous nodes.
