ISpGrammarBuilder::AddWordTransition

ISpGrammarBuilder::AddWordTransition adds a word or a sequence of words to the grammar.

HRESULT AddWordTransition(
   SPSTATEHANDLE          hFromState,
   SPSTATEHANDLE          hToState,
   const WCHAR           *psz,
   const WCHAR           *pszSeperators,
   SPGRAMMARWORDTYPE      eWordType,
   float                  Weight,
   const SPPROPERTYINFO  *pPropInfo
);

Parameters

hFromState

[in] Handle of the state from which the arc (or sequence of arcs in the case of multiple words) should originate.

hToState

[in] Handle of the state where the arc (or sequence of arcs) should terminate. If NULL, the final arc will be to the (implicit) terminal node of this grammar rule.

psz

[in] Address of a null-terminated string containing the word or words to be added. If psz is NULL, an epsilon arc will be added.

pszSeperators

[in] Address of a null-terminated string containing the transition word separation characters.
psz points to a single word if pszSeperators is NULL, or else pszSeperators specifies the valid separator characters. This parameter may not contain a forward slash ("/") as that is used for the complex word format.

eWordType

[in] The SPGRAMMARWORDTYPE enumeration that specifies the word type. Currently, only SPWT_LEXICAL is supported.

Weight

[in] Value specifying the arc's relative weight in case there are multiple arcs originating from hFromState.

pPropInfo

[in] The SPPROPERTYINFO structure containing property name and value information that is associated with this arc or sequence of arcs.
