public class PutAttributesRequest extends AmazonWebServiceRequest implements java.io.Serializable
PutAttributes operation
.
The PutAttributes operation creates or replaces attributes in an
item. The client may specify new attributes using a combination of the
Attribute.X.Name
and Attribute.X.Value
parameters. The client specifies the first attribute by the parameters
Attribute.0.Name
and Attribute.0.Value
,
the second attribute by the parameters Attribute.1.Name
and Attribute.1.Value
, and so on.
Attributes are uniquely identified in an item by their name/value
combination. For example, a single item can have the attributes
{ "first_name", "first_value" }
and { "first_name",
second_value" }
. However, it cannot have two attribute
instances where both the Attribute.X.Name
and
Attribute.X.Value
are the same.
Optionally, the requestor can supply the Replace
parameter for each individual attribute. Setting this value to
true
causes the new attribute value to replace the
existing attribute value(s). For example, if an item has the
attributes { 'a', '1' }
,
{ 'b', '2'}
and { 'b', '3'
}
and the requestor calls PutAttributes
using the
attributes { 'b', '4' }
with the Replace
parameter set to true, the final attributes of the item are changed to
{ 'a', '1' }
and { 'b', '4' }
, which
replaces the previous values of the 'b' attribute with the new value.
NOTE: Using PutAttributes to replace attribute values that do not exist will not result in an error response.
You cannot specify an empty string as an attribute name.
Because Amazon SimpleDB makes multiple copies of client data and uses an eventual consistency update model, an immediate GetAttributes or Select operation (read) immediately after a PutAttributes or DeleteAttributes operation (write) might not return the updated data.
