API Functions

1	Creating, Copying, and Releasing a LVParseTree Handle LVParseTree objects are fully copyable and assignable. Functions H_PARSE_TREE LVParseTree_Create() H_PARSE_TREE LVParseTree_CreateFromCopy(H_PARSE_TREE Other) void LVParseTree_Copy(H_PARSE_TREE Tree, H_PARSE_TREE Other) void LVParseTree_Release(H_PARSE_TREE…
2	LVParseTree_CreateIteratorBegin and LVParseTree_CreateIteratorEnd LVParseTree_CreateIteratorBegin and LVParseTree_CreateIteratorEnd provide iterators for visiting every node in the tree in a top-to-bottom, left-to-right descent. It is also the basis for the Tag and Terminal iterators. Functions H_PARSE_TREE_ITR LVParseTree_CreateIteratorBegin(H_PARSE_TREE…
3	LVParseTree_CreateTagIteratorBegin and LVParseTree_CreateTagIteratorEnd LVParseTree_CreateTagIteratorBegin and LVParseTree_CreateTagIteratorEnd provide iterators for visiting the tags in the tree's body. Functions H_PARSE_TREE_TAG_ITR LVParseTree_CreateTagIteratorBegin(H_PARSE_TREE Tree) H_PARSE_TREE_TAG_ITR LVParseTree_CreateTagIteratorEnd(H_PARSE_TREE…
4	LVParseTree_CreateTerminalIteratorBegin and LVParseTree_CreateTerminalIteratorEnd LVParseTree_CreateTerminalIteratorBegin and LVParseTree_CreateTerminalIteratorEnd 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 speech engine…
5	LVParseTree_GetGrammarLabel Returns the name of the grammar that generated this tree. Functions const char* LVParseTree_GrammarLabel (H_PARSE_TREE Tree) Parameter Tree Handle to a parse tree. Remarks LVParseTree_GetGrammarLabel( ) will always return the name of one of the grammars you…
6	LVParseTree_GetLanguage Returns the language identifier of the grammar that generated this tree. Functions const char* LVParseTree_GetLanguage(H_PARSE_TREE Tree) Parameter Tree Handle to a parse tree. Remarks This function will always return an RFC 3066 language identifier, such…
7	LVParseTree_GetMode Returns the interaction mode that created the tree. Functions const char* LVParseTree_GetMode(H_PARSE_TREE Tree) Parameter Tree Handle to a parse tree. Returns "voice" or "dtmf" See Also LVParseTree::Mode (C++ API)
8	LVParseTree_GetRoot Gets the root parse tree node. Functions H_PARSE_TREE_NODE LVParseTree_GetRoot(H_PARSE_TREE Tree); Parameter Tree Handle to a parse tree. Returns An H_PARSE_TREE_NODE handle representing the toplevel rule of the matching grammar. Remarks This node will always…
9	LVParseTree_GetTagFormat Returns the name of the tag format declared in the matching grammar for this tree. Function const char* LVParseTree_GetTagFormat(H_PARSE_TREE Tree) Parameter Tree Handle to a parse tree. See Also LVParseTree::TagFormat (C++ API)
