Class DeleteAttributesRequest

java.lang.Object
  com.amazonaws.AmazonWebServiceRequest
      com.amazonaws.services.simpledb.model.DeleteAttributesRequest

public class DeleteAttributesRequest
extends AmazonWebServiceRequest

Container for the parameters to the DeleteAttributes operation.

Deletes one or more attributes associated with an item. If all attributes of the item are deleted, the item is deleted.

NOTE: If DeleteAttributes is called without being passed any attributes or values specified, all the attributes for the item are deleted.

DeleteAttributes is an idempotent operation; running it multiple times on the same item or attribute does not result in an error response.

Because Amazon SimpleDB makes multiple copies of item data and uses an eventual consistency update model, performing a GetAttributes or Select operation (read) immediately after a DeleteAttributes or PutAttributes operation (write) might not return updated item data.

Constructs a new DeleteAttributesRequest object. Callers should use the setter or fluent setter (with...) methods to initialize any additional object members.

Parameters:

domainName - The name of the domain in which to perform the operation.

itemName - The name of the item. Similar to rows on a spreadsheet, items represent individual objects that contain one or more value-attribute pairs.

DeleteAttributesRequest

public DeleteAttributesRequest(String domainName,

Parameters:

domainName - The name of the domain in which to perform the operation.

itemName - The name of the item. Similar to rows on a spreadsheet, items represent individual objects that contain one or more value-attribute pairs.

attributes - A list of Attributes. Similar to columns on a spreadsheet, attributes represent categories of data that can be assigned to items.
