Annotation Type DynamoDBAttribute


@Retention(RUNTIME) @Target({FIELD,METHOD}) public @interface DynamoDBAttribute
Interface for marking a class property as an attribute in a DynamoDB table. Applied to the getter method or the class field for a modeled property. If the annotation is applied directly to the class field, the corresponding getter and setter must be declared in the same class.

This annotation is optional when the name of the DynamoDB attribute matches the name of the property declared in the class. When they differ, use this annotation with the attributeName() parameter to specify which DynamoDB attribute this property corresponds to. Furthermore, the DynamoDBMapper class assumes Java naming conventions, and will lower-case the first character of a getter method's property name to determine the name of the property. E.g., a method getValue() will map to the DynamoDB attribute "value". Similarly, a method isValid() maps to the DynamoDB attribute "valid".

Even getter method not marked with this annotation are assumed to be modeled properties, unless marked with DynamoDBIgnore.
