Detailed Description

template<class E>
class ogdf::List< E >

Doubly linked lists (maintaining the length of the list).

Use ogdf::ListConstIterator or ogdf::ListIterator in order to iterate over the list.

In contrast to ogdf::ListPure, instances of ogdf::List store the length of the list.

Template Parameters

E	is the data type stored in list elements.
