Interface DynamoDbMarshaller<T>

All Known Implementing Classes:

AbstractEnumMarshaller, JsonMarshaller

Deprecated.

Replaced by DynamoDbTypeConverter

A DynamoDbTypeConverted with 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 DynamoDbTypeConverted is created per field/attribute. In the old, an new instance of the marshaller was created for each call to marshall and 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
