LVParseTree::TerminalIterator

An LVParseTree::TerminalIterator object is an adaptation of the standard LVParseTree::Iterator. It only visits the nodes in a tree that are terminals. You get a TerminalIterator by calling:

Return Type	Function	Description

	Iterator(void)	Constructs a blank TerminalIterator; its not pointing over anything.
	Iterator(const TerminalIterator& other)	Copy constructor.
LVParseTree::TerminalIterator&	operator=(const TerminalIterator& other)	Assignment operator.
	~TerminalIterator(void)	Destructor.

LVParseTree::TerminalIterator&	operator ++ (void)	pre-increments the iterator (++itr).
LVParseTree::TerminalIterator	operator ++ (int)	post-increments the iterator (itr++).
const LVParseTree::Node*	operator -> (void)	provides pointer-like access to the node the iterator is currently over ( e.g const char* text = itr->Text( ) )
const LVParseTree::Node&	operator * (void)	provides access to the node the iterator is currently over (e.g. LVParseTree::Node n = *itr )
bool	operator==(const TerminalIterator& other)	Tests equality with another TerminalIterator. Two TerminalIterators are equal if they are pointing to the same node in the same tree. (e.g if itr1 == itr2 do something)
bool	operator!=(const TerminalIterator& other)	returns true if and only if the equality operator returns false.
