bridges.base.DLelement< E > Class Template Reference

Inheritance diagram for bridges.base.DLelement< E >:

Detailed Description

This class is used to create doubly linked element objects.

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.

(

)

This method gets the data structure type

Returns

The date structure type as a string

Reimplemented from bridges.base.SLelement< E >.

Reimplemented in bridges.base.CircDLelement< E >.

getDataStructureRepresentation()

String bridges.base.DLelement< E >.getDataStructureRepresentation

(

)

Get the JSON representation of the the data structure

Returns

the JSON string of the element's representation

Reimplemented from bridges.base.SLelement< E >.

getNext()

DLelement<E> bridges.base.DLelement< E >.getNext

(

reverse_iterator()

Iterator<E> bridges.base.DLelement< E >.reverse_iterator

(

)

Return an reverse iterator over the elements in the array. This is generally not called directly, but is called by Java when used in a "simple" for loops

(

DLelement< E >

prv

)

This method sets the pointer to the previous DLelement
