LVParseTree::TerminalsBegin and LVParseTree::TerminalsEnd

TerminalsBegin and TerminalsEnd provide access to the "terminals" of the tree.  Terminals are the words and phrases in your grammar, so a TerminalIterator gives you access the the exact words the engine heard a speaker say to match a grammar, in the order that the engine heard those words.

Functions

LVParseTree::TerminalIterator TerminalsBegin()

LVParseTree::TerminalIterator TerminalsEnd()

Example

The following code prints out the sentence engine heard, with a word-level confidence score attached to each word.

LVParseTree::TerminalIterator Itr = Tree.TerminalsBegin();
LVParseTree::TerminalIterator End = Tree.TerminalsEnd();

for (; Itr != End; ++Itr)
{
     cout << "\"" << Itr->Text() << "\"":(" << Itr->Score() << ") ";
}
cout << endl;

So if the grammar being used was the top level navigation example grammar, and the engine recognized "go back", then the output of the above code might look like:

"go":(850) "back":(901)
