C# Class OpenADK.Library.Tools.Mapping.DataReaderAdaptor

Implements IFieldAdaptor for the ADK, based on an IDataReader instance.

To use this class, create an instance of it based on an open IDataReader instance. You are responsible for navigation of the IDataReader by calling IDataReader.Read. When you are ready to map the current IDataReader row to a SIFElement, pass this class into the MappingsContext.MapOutbound() method.

Public Methods

Method	Description
DataReaderAdaptor ( IDataReader reader ) : System
GetSifValue ( string fieldName, TypeConverter typeConverter, FieldMapping mapping ) : SifSimpleType	Gets a value from the underlying data store to be used in an outbound field mapping operation
GetValue ( string key ) : object	Returns the underlying value being stored for the field. This method is not called during Mappings operations. It may be called by classes such as the OpenADK.Library.IValueBuilder class
HasField ( string fieldName ) : bool	Returns whether the field being requested for mapping has a value that can be mapped to SIF
SetSifValue ( string fieldName, SifSimpleType value, FieldMapping mapping ) : void	Sets a value that has been retrieved from a SIF Element in an inbound field mapping operation.
