bridges.ml_element.MLelement Class Reference

Inheritance diagram for bridges.ml_element.MLelement:

Detailed Description

This class can be used to instantiate Multi-list Elements.

This class extends SLelement (singly linked list element) to build multi-lists; Multilist elements contain a tag (boolean) that indicates if the element contains a sublist or not; if the tag is true, then there is a sublist beginning at this node and the starting point is the ‘sublist’ field in the element. If the tag is false, then the list continues as a normal singly linked list. The sublists are re recursive: any sublist can have its own sublists and so on. As in singly linked elements, the next pointer points to the following list element and each element contains a generic application specific object.

Multi-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, for instance, between the current element and its next element. In this case, the link in question is that which connects the element to the following elements; a similar logic follows for sublists.
