Detailed Description

template<class PAYLOAD>
class TreeItem< PAYLOAD >

Template class for tree items that can handle tree children in a generic way - firstChild(), next() and parent(). Each item stores one value of type 'PAYLOAD'.

Class 'PAYLOAD' needs to provide operator=().


Constructor & Destructor Documentation

template<class PAYLOAD>
TreeItem< PAYLOAD >::TreeItem ( const PAYLOAD &  val,
TreeItem< PAYLOAD > *  parent = 0 
) [inline]

Constructor. Creates a new tree item with value "val" and inserts it ( without maintaining any meaningful sort order! ) into the children list of "parent".

template<class PAYLOAD>
TreeItem< PAYLOAD >::TreeItem ( PAYLOAD  val,
bool  autoAddChild,
TreeItem< PAYLOAD > *  parent = 0 
) [inline, protected]

Constructor to be called for derived classes: Decide whether or not to automatically insert this item into the parent's children list. Useful for derived classes that want to maintain a specific sort order among children.

template<class PAYLOAD>
virtual TreeItem< PAYLOAD >::~TreeItem ( ) [inline, virtual]

Destructor. Takes care of children - they will be deleted along with this item.


Member Function Documentation

template<class PAYLOAD>
void TreeItem< PAYLOAD >::addChild ( TreeItem< PAYLOAD > *  newChild) [inline]

Add a child to the internal children list - usually called from within the child's default constructor.

This default method does not maintain any meaningful sorting order - derived classes that require this might want to use the other constructor ( with 'autoAddChild' set to 'false' ) take care of child insertion themselves.

template<class PAYLOAD>
TreeItem<PAYLOAD>* TreeItem< PAYLOAD >::firstChild ( ) const [inline]

Returns this item's first child or 0 if there is none.

Reimplemented in SortedTreeItem< PAYLOAD >.

template<class PAYLOAD>
TreeItem<PAYLOAD>* TreeItem< PAYLOAD >::next ( ) const [inline]

Returns this item's next sibling or 0 if there is none.

Reimplemented in SortedTreeItem< PAYLOAD >.

template<class PAYLOAD>
TreeItem<PAYLOAD>* TreeItem< PAYLOAD >::parent ( ) const [inline]

Returns this item's parent or 0 if there is none.

Reimplemented in SortedTreeItem< PAYLOAD >.

template<class PAYLOAD>
void TreeItem< PAYLOAD >::setFirstChild ( TreeItem< PAYLOAD > *  newFirstChild) [inline]

Sets this item's first child.

template<class PAYLOAD>
void TreeItem< PAYLOAD >::setNext ( TreeItem< PAYLOAD > *  newNext) [inline]

Sets this item's next sibling.

template<class PAYLOAD>
void TreeItem< PAYLOAD >::setParent ( TreeItem< PAYLOAD > *  newParent) [inline]

Sets this item's parent.

template<class PAYLOAD>
void TreeItem< PAYLOAD >::setValue ( PAYLOAD  newValue) [inline]

Set this item's value, the "payload".

If the sort order among children of one level is important, overwrite this method and change the sort order according to the new value. The template class itself never calls this.

template<class PAYLOAD>
const PAYLOAD& TreeItem< PAYLOAD >::value ( ) const [inline]

Returns this item's value, the "payload".
