org.eclipse.persistence.mappings.converters.Converter

Purpose: Conversion interface to allow conversion between object and data types. This can be used in any mapping to convert between the object and data types without requiring code placed in the object model. TopLink provides several common converters, but the application can also define it own. @see DirectToFieldMapping#setConverter(Converter) @see DirectCollectionMapping#setConverter(Converter) @see ObjectTypeConverter @see TypeConversionConverter @author James Sutherland @since OracleAS TopLink 10g (10.0.3)
