Method Detail

requestItems

public Map<String,List<WriteRequest>> requestItems()

A map of one or more table names and, for each table, a list of operations to be performed ( DeleteRequest or PutRequest). Each element in the map consists of the following:

• DeleteRequest - Perform a DeleteItem operation on the specified item. The item to be deleted is identified by a Key subelement:

  • Key - A map of primary key attribute values that uniquely identify the item. Each entry in this map consists of an attribute name and an attribute value. For each primary key, you must provide all of the key attributes. For example, with a simple primary key, you only need to provide a value for the partition key. For a composite primary key, you must provide values for both the partition key and the sort key.

• PutRequest - Perform a PutItem operation on the specified item. The item to be put is identified by an Item subelement:

  • Item - A map of attributes and their values. Each entry in this map consists of an attribute name and an attribute value. Attribute values must not be null; string and binary type attributes must have lengths greater than zero; and set type attributes must not be empty. Requests that contain empty values will be rejected with a ValidationException exception.

    If you specify any attributes that are part of an index key, then the data types for those attributes must match those of the schema in the table's attribute definition.

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

Returns:

A map of one or more table names and, for each table, a list of operations to be performed ( DeleteRequest or PutRequest). Each element in the map consists of the following:

• DeleteRequest - Perform a DeleteItem operation on the specified item. The item to be deleted is identified by a Key subelement:

  • Key - A map of primary key attribute values that uniquely identify the item. Each entry in this map consists of an attribute name and an attribute value. For each primary key, you must provide all of the key attributes. For example, with a simple primary key, you only need to provide a value for the partition key. For a composite primary key, you must provide values for both the partition key and the sort key.

• PutRequest - Perform a PutItem operation on the specified item. The item to be put is identified by an Item subelement:

  • Item - A map of attributes and their values. Each entry in this map consists of an attribute name and an attribute value. Attribute values must not be null; string and binary type attributes must have lengths greater than zero; and set type attributes must not be empty. Requests that contain empty values will be rejected with a ValidationException exception.

    If you specify any attributes that are part of an index key, then the data types for those attributes must match those of the schema in the table's attribute definition.

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.

returnConsumedCapacityAsString

public String returnConsumedCapacityAsString()

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 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 are returned in the response. If set to NONE (the default), no statistics are returned.

getValueForField

public <T> Optional<T> getValueForField(String fieldName,
                                        Class<T> clazz)

Description copied from class: SdkRequest

Used to retrieve the value of a field from any class that extends SdkRequest. The field name specified should match the member name from the corresponding service-2.json model specified in the codegen-resources folder for a given service. The class specifies what class to cast the returned value to. If the returned value is also a modeled class, the SdkRequest.getValueForField(String, Class) method will again be available.

Overrides:

getValueForField in class SdkRequest

Parameters:

fieldName - The name of the member to be retrieved.

clazz - The class to cast the returned object to.

Returns:

Optional containing the casted return value
