Container for the parameters to the BatchDeleteAttributes operation.

Performs multiple DeleteAttributes operations in a single call, which reduces round trips and latencies. This enables Amazon SimpleDB to optimize requests, which generally yields better throughput.

NOTE: If you specify BatchDeleteAttributes without attributes or values, all the attributes for the item are deleted. BatchDeleteAttributes is an idempotent operation; running it multiple times on the same item or attribute doesn't result in an error. The BatchDeleteAttributes operation succeeds or fails in its entirety. There are no partial deletes. You can execute multiple BatchDeleteAttributes operations and other operations in parallel. However, large numbers of concurrent BatchDeleteAttributes calls can result in Service Unavailable (503) responses. This operation is vulnerable to exceeding the maximum URL size when making a REST request using the HTTP GET method. This operation does not support conditions using Expected.X.Name, Expected.X.Value, or Expected.X.Exists.

The following limitations are enforced for this operation:

  • 1 MB request size
  • 25 item limit per BatchDeleteAttributes operation

 
 public class BatchDeleteAttributesRequest extends AmazonWebServiceRequest implements Serializable {

    
The name of the domain in which the attributes are being deleted.
 
     private String domainName;

    
A list of items on which to perform the operation.
 
Default constructor for a new BatchDeleteAttributesRequest object. Callers should use the setter or fluent setter (with...) methods to initialize this object after creating it.
 
     public BatchDeleteAttributesRequest() {}
    
    
Constructs a new BatchDeleteAttributesRequest 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 the attributes are being deleted.
items A list of items on which to perform the operation.
 
     public BatchDeleteAttributesRequest(String domainNamejava.util.List<DeletableItemitems) {
         setDomainName(domainName);
         setItems(items);
     }

    
The name of the domain in which the attributes are being deleted.

Returns:
The name of the domain in which the attributes are being deleted.
 
     public String getDomainName() {
         return ;
     }
    
    
The name of the domain in which the attributes are being deleted.

Parameters:
domainName The name of the domain in which the attributes are being deleted.
    public void setDomainName(String domainName) {
        this. = domainName;
    }
    
    
The name of the domain in which the attributes are being deleted.

Returns a reference to this object so that method calls can be chained together.

Parameters:
domainName The name of the domain in which the attributes are being deleted.
Returns:
A reference to this updated object so that method calls can be chained together.
    public BatchDeleteAttributesRequest withDomainName(String domainName) {
        this. = domainName;
        return this;
    }

    
A list of items on which to perform the operation.

Returns:
A list of items on which to perform the operation.
    public java.util.List<DeletableItemgetItems() {
        if ( == null) {
               = new com.amazonaws.internal.ListWithAutoConstructFlag<DeletableItem>();
              .setAutoConstruct(true);
        }
        return ;
    }
    
    
A list of items on which to perform the operation.

Parameters:
items A list of items on which to perform the operation.
    public void setItems(java.util.Collection<DeletableItemitems) {
        if (items == null) {
            this. = null;
            return;
        }
        itemsCopy.addAll(items);
        this. = itemsCopy;
    }
    
    
A list of items on which to perform the operation.

Returns a reference to this object so that method calls can be chained together.

Parameters:
items A list of items on which to perform the operation.
Returns:
A reference to this updated object so that method calls can be chained together.
        if (getItems() == nullsetItems(new java.util.ArrayList<DeletableItem>(items.length));
        for (DeletableItem value : items) {
            getItems().add(value);
        }
        return this;
    }
    
    
A list of items on which to perform the operation.

Returns a reference to this object so that method calls can be chained together.

Parameters:
items A list of items on which to perform the operation.
