/**
 * Marshaller interface for storing complex types in DynamoDB as Strings.
 * Implementors provide methods to transform instances of a class to and from
 * Strings.
 *
 * @deprecated Replaced by {@link DynamoDBTypeConverter}
 *
 * 

A {@link DynamoDBTypeConverted} with {@link String} as source would * perform the same conversion. Please consider, if your marshaller is thread * safe before replacing. In the new implementation, a single instance of * {@link DynamoDBTypeConverted} is created per field/attribute. In the old, * an new instance of the marshaller was created for each call to * {@code marshall} and {@code unmarshall}. If your marshaller/converter is not * thread safe, it is recomended to specify a converter which will instantiate * a new marshaller per call.

* *
 * public class CustomConverter<T> implements DynamoDBTypeConverter<String,T> {
 *     @Override
 *     public final String convert(final T object) {
 *         return ...
 *     }
 *     @Override
 *     public final T unconvert(final String object) {
 *         return ...
 *     }
 * }

*/ @Deprecated public interface DynamoDBMarshaller { /** * Turns an object of type T into its String representation. */ public String marshall(T getterReturnResult); /** * Turns a String representation of an object of type T into an object. */ public T unmarshall(Class clazz, String obj); }
