Annotation Type DynamoDBTypeConvertedJson

@Retention(value=RUNTIME)
 @Target(value={TYPE,FIELD,METHOD})
public @interface DynamoDBTypeConvertedJson

A simple JSON converter that uses the Jackson JSON processor.

It shares all limitations of that library. For more information about Jackson, see: http://wiki.fasterxml.com/JacksonHome

 @DynamoDBTypeConvertedJson
 public Currency getCurrency()
 

Where,

 public class Currency {
     private Double amount;
     private String unit;

     public Double getAmount() { return amount; }
     public void setAmount(Double amount) { this.amount = amount; }

     public String getUnit() { return unit; }
     public void setUnit(String unit) { this.unit = unit; }
 }
 

Would write the following value to DynamoDB given,

• Currency(79.99,"USD") = "{\"amount\":79.99,\"unit\":\"USD\"}"
