Public Member Functions

virtual ~TNode ()
 each virtual class needs a virtual destructor (this one does nothing)
TNodeType nodeType () const
 returns the type of this node
short priority () const
 returns the node priority
TNode< T > * parent () const
 returns the parent node (returns 0 if this node is the root node)
virtual TNode< T > * left () const
 returns the left child node (returns 0 if this node doesn't support one)
virtual TNode< T > * right () const
 returns the right child node (returns 0 if this node doesn't support one)
virtual void accept (TNodeVisitor< T > &)=0
 calls the visit method in TNodeVisitor<>
virtual TNode< T > * clone () const =0
 clones that node
iterator begin ()
 iterator access to the first value node in this operator level
iterator end ()
 iterator access to the end
virtual bool equals (const TNode< T > *ANode) const =0
 returns true, if given node equals to this one

Protected Member Functions

 TNode (TNodeType ANodeType, short APriority, TNode< T > *AParentNode=0)
 initializes this node for given node type.
 TNode (const TNode< T > &n)
void parent (TNode< T > *AParent)
 initializes the parent node with the given one

Detailed Description

template<typename T>
class math::TNode< T >

TNode<T> represents the abstract node base.

Member Enumeration Documentation

template<typename T>
enum math::TNode::TNodeType

This enumeration, TNodeType, is implemented for node type access. This makes it also faster because it replaces the dynamic_cast<> operator.
