LVParseTree::Iterator

Reference Number: AA-00979 Views: 864 0 Rating/ Voters

An LVParseTree::Iterator Object traverses a parse tree in a top-to-bottom, left-to-right fashion (sometimes called a pre-order or LL traversal)

Use <LVSpeechPort.h> or <LV_SRE_ParseTree.h>

Function Return Type Description
Iterator(void)   Constructs a blank Iterator; its not pointing over anything.
Iterator(const Iterator& other)   Copy constructor.
operator=(const Iterator& other) LVParseTree::Iterator& Assignment operator.
~Iterator(void)   Destructor.
operator ++ (void) LVParseTree::Iterator& pre-increments the iterator (++itr).
operator ++ (int) LVParseTree::Iterator post-increments the iterator (itr++).
operator -> (void) const LVParseTree::Node* provides pointer-like access to the node the iterator is currently over
( e.g const char* text = itr->Text( ) )
operator * (void) const LVParseTree::Node& provides access to the node the iterator is currently over
(e.g. LVParseTree::Node n  = *itr )
operator == (const Iterator& other) bool Tests equality with another Iterator.  Two Iterators are equal if they are pointing to the same node in the same tree.
operator != (const Iterator& other) bool returns true if and only if the equality operator returns false.
