@Retention(value=RUNTIME) @Target(value={FIELD,METHOD}) public @interface DynamoDBAttribute
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".
Getter methods not marked with this annotation are assumed to be modeled
properties, unless marked with DynamoDBIgnore
.
