Grammar::IsStg Property

Gets whether a grammar is strongly typed.

Namespace:  System.Speech.Recognition
Assembly:  System.Speech (in System.Speech.dll)

protected public:
virtual property bool IsStg {
	bool get ();
}

Property Value

Type: System::Boolean
The IsStg property returns true if the grammar is strongly-typed; otherwise the property returns false.

A strongly-typed Grammar object (IsStg equals true) can return strongly-typed results (objects, rather than raw text) to a client application. For example, a strongly-typed grammar might return DataTime objects rather than raw recognized input.

You can implement strongly-typed grammars by attaching code to the rules of a grammar. As a recognition engine processes any given rule, taking as input the current partial results, the associated code is executed and the textual information becomes rich type objects. This allows a client to more easily make use of enhanced semantic checking, support for multiple cultures, and internal grammar logic.

Instances of strongly-typed Grammar objects are typically obtained from resources in an assembly as a Type of the Common Language Runtime (CLR). The localized types used to support different languages are examples of such Grammar objects.

Notes to Inheritors

Strongly-typed grammars inheriting from Grammar need to override the default behavior of IsStg, which is to return false.
