SplDoublyLinkedList::bottom - Peeks at the node from the beginning of the doubly linked list
SplDoublyLinkedList::__construct - Constructs a new doubly linked list
SplDoublyLinkedList::count - Counts the number of elements in the doubly linked list.
SplDoublyLinkedList::current - Return current array entry
SplDoublyLinkedList::getIteratorMode - Returns the mode of iteration
SplDoublyLinkedList::isEmpty - Checks whether the doubly linked list is empty.
SplDoublyLinkedList::key - Return current node index
SplDoublyLinkedList::next - Move to next entry
SplDoublyLinkedList::offsetExists - Returns whether the requested $index exists
SplDoublyLinkedList::offsetGet - Returns the value at the specified $index
SplDoublyLinkedList::offsetSet - Sets the value at the specified $index to $newval
SplDoublyLinkedList::offsetUnset - Unsets the value at the specified $index
SplDoublyLinkedList::pop - Pops a node from the end of the doubly linked list
SplDoublyLinkedList::prev - Move to previous entry
SplDoublyLinkedList::push - Pushes an element at the end of the doubly linked list
SplDoublyLinkedList::rewind - Rewind iterator back to the start
SplDoublyLinkedList::setIteratorMode - Sets the mode of iteration
SplDoublyLinkedList::shift - Shifts a node from the beginning of the doubly linked list
SplDoublyLinkedList::top - Peeks at the node from the end of the doubly linked list
