ITypeHandlerCallback Members

The null value for this type

GetResult	Performs processing on a value before after it has been retrieved from a IDataReader.
SetParameter	Performs processing on a value before it is used to set the parameter of a IDbCommand.
ValueOf	Casts the string representation of a value into a type recognized by this type handler. This method is used to translate nullValue values into types that can be appropriately compared. If your custom type handler cannot support nullValues, or if there is no reasonable string representation for this type (e.g. File type), you can simply return the String representation as it was passed in. It is not recommended to return null, unless null was passed in.
