Examples of com.amazonaws.services.dynamodb.model.UpdateItemRequest

com.amazonaws.services.dynamodb.model.UpdateItemRequest
Container for the parameters to the {@link com.amazonaws.services.dynamodb.AmazonDynamoDB#updateItem(UpdateItemRequest) UpdateItem operation}.
Edits an existing item's attributes.

You can perform a conditional update (insert a new attribute name-value pair if it doesn't exist, or replace an existing name-value pair if it has certain expected attribute values).
