// Class : LinkedListNode
|
|
// Description : This just stores the pointers to implement a
|
|
// doubly-linked list of some kind of object. There are
|
|
// occasions when a hand-rolled linked list is more
|
|
// appropriate than an STL container.
|
|
//
|
|
// Typically, each node of the linked list, as well as
|
|
// the root of the list, will inherit from this class.
|
|
//
|
|
// Note that this class is not inherently thread-safe;
|
|
// derived classes are responsible for protecting any
|
|
// calls into it within mutexes, if necessary.
