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).
@see com.amazonaws.services.dynamodb.AmazonDynamoDB#updateItem(UpdateItemRequest)

        Key key = new Key();
        key.setHashKeyElement(new AttributeValue().withS("1"));


        HashMap<String, AttributeValueUpdate> dynValues = new HashMap<String, AttributeValueUpdate> ();
        dynValues.put("value", new AttributeValueUpdate(new AttributeValue().withN("1"), AttributeAction.ADD));
        UpdateItemRequest update = new UpdateItemRequest(tableName, key, dynValues);
        getClient().updateItem(update);


        inProcessClient.save(PERSISTENCE_PATH);
        createNewInProcessClient().restore(PERSISTENCE_PATH);
