template<class Key, class Value>
XFcHashtableIterator< Key, Value >::XFcHashtableIterator | ( | XFcHashtable< Key, Value > * | aHashtable,
|  | typename XFcLinkedList< XFcHashtableNode< Key, Value > * >::forwardIterator | aIterator
| ) | `[private]`

| Creates an iterator pointing to a certain node.

## Member Function Documentation

template<class Key, class Value>
Key XFcHashtableIterator< Key, Value >::getKey | ( |  | ) | const

| Returns the key from this key-value pair.

template<class Key, class Value>
Value XFcHashtableIterator< Key, Value >::getValue | ( |  | ) | const

| Returns the value from this key-value pair.

template<class Key, class Value>
INT XFcHashtableIterator< Key, Value >::isValid | ( |  | ) | const

| Returns information about the validity of the node. Returns: 1 if the node is valid, 0 otherwise.

template<class Key, class Value>
INT XFcHashtableIterator< Key, Value >::operator!= | ( | const XFcHashtableIterator< Key, Value > & | aRef | ) | const

  | Inequality check. Tests if two nodes are inequal. Parameters:
  aRef | iterator to test this iterator against.
Returns: 1 if inequal, 0 otherwise.

template<class Key, class Value>
XFcHashtableIterator< Key, Value > XFcHashtableIterator< Key, Value >::operator++ | ( | int |  | ) |

| Advances to the next node, post-operation. Returns: next node.

template<class Key, class Value>
XFcHashtableIterator< Key, Value > & XFcHashtableIterator< Key, Value >::operator++ | ( |  | ) |

| Advances to the next node, pre-operation. Returns: reference to next node.

template<class Key, class Value>
XFcHashtableIterator< Key, Value > & XFcHashtableIterator< Key, Value >::operator= | ( | const XFcHashtableIterator< Key, Value > & | aClone | ) |

  | Makes this iterator a copy of another iterator. Parameters:
  aClone | iterator to copy state from.
Returns: reference to this iterator.

template<class Key, class Value>
INT XFcHashtableIterator< Key, Value >::operator== | ( | const XFcHashtableIterator< Key, Value > & | aRef | ) | const

  | Equality check. Tests if two nodes are equal. Parameters:
  aRef | iterator to test this iterator against.
Returns: 1 if equal, 0 otherwise.

template<class Key, class Value>
Value XFcHashtableIterator< Key, Value >::setValue | ( | const Value | aValue | ) |

  | Sets the value of this key-value pair. Parameters:
  aValue | new value to set.
