Method Details

hasRequestItems
public final boolean hasRequestItems()For responses, this returns true if the service returned a value for the RequestItems property. This DOES NOT check that the value is non-empty (for which, you should check theisEmpty()
method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified. -
requestItems
A map of one or more table names or table ARNs and, for each table, a list of operations to be performed (
DeleteRequest
orPutRequest
). Each element in the map consists of the following:-
DeleteRequest
- Perform aDeleteItem
operation on the specified item. The item to be deleted is identified by aKey
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 aPutItem
operation on the specified item. The item to be put is identified by anItem
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 are rejected with aValidationException
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.
This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the
hasRequestItems()
method.- Returns:
- A map of one or more table names or table ARNs and, for each table, a list of operations to be performed
(
DeleteRequest
orPutRequest
). Each element in the map consists of the following:-
DeleteRequest
- Perform aDeleteItem
operation on the specified item. The item to be deleted is identified by aKey

For a composite primary key, you must provide values for both the partition key and the sort key.

- Perform aPutItem
operation on the specified item. The item to be put is identified by anItem
subelement:-

- 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 are rejected with aValidationException
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
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 returnReturnConsumedCapacity.UNKNOWN_TO_SDK_VERSION

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 toNONE

equalsBySdkFields
Description copied from interface:SdkPojo
Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in anSdkPojo
class, and is generated based on a service model.If an
SdkPojo
class does not have any inherited fields,equalsBySdkFields
andequals
are essentially the same.- Specified by:
equalsBySdkFields
in interfaceSdkPojo
- Parameters:
obj
- the object to be compared with- Returns:
- true if the other object equals to this object by sdk fields, false otherwise.
-
toString
Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value. -
getValueForField
Description copied from class:SdkRequest
Used to retrieve the value of a field from any class that extendsSdkRequest
. 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, theSdkRequest.getValueForField(String, Class)
method will again be available.- Overrides:
getValueForField
in classSdkRequest
- 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
