ITypeHandlerCallback Interface
A simple interface for implementing custom type handlers. Using this interface, you can implement a type handler that will perform customized processing before parameters are set on a IDbCommand and after values are retrieved from a IDataReader. Using a custom type handler you can extend the framework to handle types that are not supported, or handle supported types in a different way. For example, you might use a custom type handler to implement proprietary BLOB support (e.g. Oracle), or you might use it to handle booleans using "Y" and "N" instead of the more typical 0/1.
