Method Detail

hasTransactItems

public boolean hasTransactItems()

Returns true if the TransactItems property was specified by the sender (it may be empty), or false if the sender did not specify the value (it will be empty). For responses returned by the SDK, the sender is the AWS service.

transactItems

public List<TransactWriteItem> transactItems()

An ordered array of up to 25 TransactWriteItem objects, each of which contains a ConditionCheck, Put, Update, or Delete object. These can operate on items in different tables, but the tables must reside in the same AWS account and Region, and no two of them can operate on the same item.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

You can use hasTransactItems() to see if a value was sent in this field.

Returns:

An ordered array of up to 25 TransactWriteItem objects, each of which contains a ConditionCheck, Put, Update, or Delete object. These can operate on items in different tables, but the tables must reside in the same AWS account and Region, and no two of them can operate on the same item.

returnConsumedCapacity

public ReturnConsumedCapacity returnConsumedCapacity()

Returns the value of the ReturnConsumedCapacity property for this object.

If the service returns an enum value that is not available in the current SDK version, returnConsumedCapacity will return ReturnConsumedCapacity.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from returnConsumedCapacityAsString().

Returns:

The value of the ReturnConsumedCapacity property for this object.

ReturnConsumedCapacity

returnConsumedCapacityAsString

public String returnConsumedCapacityAsString()

Returns the value of the ReturnConsumedCapacity property for this object.

If the service returns an enum value that is not available in the current SDK version, returnConsumedCapacity will return ReturnConsumedCapacity.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from returnConsumedCapacityAsString().

Returns:

The value of the ReturnConsumedCapacity property for this object.

returnItemCollectionMetrics

public ReturnItemCollectionMetrics returnItemCollectionMetrics()

Determines whether item collection metrics are returned. If set to SIZE, the response includes statistics about item collections (if any), that were modified during the operation and are returned in the response. If set to NONE (the default), no statistics are returned.

If the service returns an enum value that is not available in the current SDK version, returnItemCollectionMetrics will return ReturnItemCollectionMetrics.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from returnItemCollectionMetricsAsString().

Returns:

Determines whether item collection metrics are returned. If set to SIZE, the response includes statistics about item collections (if any), that were modified during the operation and are returned in the response. If set to NONE (the default), no statistics are returned.

returnItemCollectionMetricsAsString

public String returnItemCollectionMetricsAsString()

Determines whether item collection metrics are returned. If set to SIZE, the response includes statistics about item collections (if any), that were modified during the operation and are returned in the response. If set to NONE (the default), no statistics are returned.

If the service returns an enum value that is not available in the current SDK version, returnItemCollectionMetrics will return ReturnItemCollectionMetrics.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from returnItemCollectionMetricsAsString().

Returns:

clientRequestToken

public String clientRequestToken()

Providing a ClientRequestToken makes the call to TransactWriteItems idempotent, meaning that multiple identical calls have the same effect as one single call.

Although multiple identical calls using the same client request token produce the same result on the server (no side effects), the responses to the calls might not be the same. If the ReturnConsumedCapacity> parameter is set, then the initial TransactWriteItems call returns the amount of write capacity units consumed in making the changes. Subsequent TransactWriteItems calls with the same client token return the number of read capacity units consumed in reading the item.

A client request token is valid for 10 minutes after the first request that uses it is completed. After 10 minutes, any request with the same client token is treated as a new request. Do not resubmit the same request with the same client token for more than 10 minutes, or the result might not be idempotent.

If you submit a request with the same client token but a change in other parameters within the 10-minute idempotency window, DynamoDB returns an IdempotentParameterMismatch exception.

Returns:
