ISpDataKey (Windows Embedded CE 6.0)
1/6/2010
This interface provides a mechanism for storing and retrieving string and other data. The main use for this interface is in conjunction with object tokens, which implement the ISpObjectToken interface (which inherits from ISpDataKey). For example, data can be stored in an object token representing a recognizer or TTS engine by using this interface.
When to Implement
- SpObjectToken is the standard class used for all existing SAPI object tokens. The data for each object token is stored in the registry.
- SpDataKey is a class that stores the data associated with the data key in the registry.
Applications or engines can implement this interface directly to provide a custom data key implementation.
