Detailed Description

template<typename E>
class bridges::datastructure::DLelement< E >

The doubly linked list element, derived from SLelement.

This class extends the SLelelement class by adding a previous DLelement pointer

There is a tutorial about Doubly Linked Lists : https://bridgesuncc.github.io/tutorials/DoublyLinkedList.html

Parameters

E	the application data type
