Detailed Description

template<class T>
class semf::LinkedList< T >::Node

Implements the previous() and next() functionality for every element in a list.

A class type using LinkedList has to inherit from this class.

Member Function Documentation

isInAList()

template<class T >

bool semf::LinkedList< T >::Node::isInAList ( )

inline

Returns if a node is part of a LinkedList.

Note

This is done by checking if the pointer to the previous and next element is nullptr.

Returns

false for is not in a LinkedList, otherwise true.

Definition at line 97 of file linkedlist.h.

next()

template<class T >

T * semf::LinkedList< T >::Node::next ( ) const

inline

Returns a pointer to the next element in a list.

Attention

The last element in a list will return nullptr.

Returns

The next element in a list.

Definition at line 61 of file linkedlist.h.

Here is the caller graph for this function:

previous()

template<class T >

T * semf::LinkedList< T >::Node::previous ( ) const

inline

Returns a pointer to the previous element in a list.

Attention

The first element in a list will return nullptr.

Returns

The previous element in a list.

Definition at line 79 of file linkedlist.h.

Here is the caller graph for this function:

setNext()

template<class T >

void semf::LinkedList< T >::Node::setNext ( T *  next )

inline

Sets a pointer to the next element in a list.

Attention

Do not use outside LinkedList. That leads to undefined behavior.

Parameters

next	The next element in a list.

Definition at line 70 of file linkedlist.h.

Here is the call graph for this function:

setPrevious()

template<class T >

void semf::LinkedList< T >::Node::setPrevious ( T *  previous )

inline

Sets a pointer to the previous element in a list.

Attention

Do not use outside LinkedList. That leads to undefined behavior.

Parameters

previous

The previous element in a list.
