  • Method Details

    • hasResponses

      public final boolean hasResponses()
      For responses, this returns true if the service returned a value for the Responses property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() 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.

    • responses

      public final Map<String,List<Map<String,AttributeValue>>> responses()

      A map of table name or table ARN to a list of items. Each object in Responses consists of a table name or ARN, along with a map of attribute data consisting of the data type and attribute value.

      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 hasResponses() method.

      Returns:
      A map of table name or table ARN to a list of items. Each object in Responses consists of a table name or ARN, along with a map of attribute data consisting of the data type and attribute value.

    • hasUnprocessedKeys

      public final boolean hasUnprocessedKeys()
      For responses, this returns true if the service returned a value for the UnprocessedKeys property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() 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.

    • unprocessedKeys

      public final Map<String,KeysAndAttributes> unprocessedKeys()

      A map of tables and their respective keys that were not processed with the current response. The UnprocessedKeys value is in the same form as RequestItems, so the value can be provided directly to a subsequent BatchGetItem operation. For more information, see RequestItems in the Request Parameters section.

      Each element consists of:

      • Keys - An array of primary key attribute values that define specific items in the table.

      • ProjectionExpression - One or more attributes to be retrieved from the table or index. By default, all attributes are returned. If a requested attribute is not found, it does not appear in the result.

      • ConsistentRead - The consistency of a read operation. If set to true, then a strongly consistent read is used; otherwise, an eventually consistent read is used.

      If there are no unprocessed keys remaining, the response contains an empty UnprocessedKeys map.

      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 hasUnprocessedKeys() method.

      Returns:
      A map of tables and their respective keys that were not processed with the current response. The UnprocessedKeys value is in the same form as RequestItems, so the value can be provided directly to a subsequent BatchGetItem operation. For more information, see RequestItems in the Request Parameters section.

      Each element consists of:

      • Keys - An array of primary key attribute values that define specific items in the table.

      • ProjectionExpression - One or more attributes to be retrieved from the table or index. By default, all attributes are returned. If a requested attribute is not found, it does not appear in the result.

      • ConsistentRead - The consistency of a read operation. If set to true, then a strongly consistent read is used; otherwise, an eventually consistent read is used.

      If there are no unprocessed keys remaining, the response contains an empty UnprocessedKeys map.

    • hasConsumedCapacity

      public final boolean hasConsumedCapacity()
      For responses, this returns true if the service returned a value for the ConsumedCapacity property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() 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.

    • consumedCapacity

      public final List<ConsumedCapacity> consumedCapacity()

      The read capacity units consumed by the entire BatchGetItem operation.

      Each element consists of:

      • TableName - The table that consumed the provisioned throughput.

      • CapacityUnits - The total number of capacity units consumed.

      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 hasConsumedCapacity() method.

      Returns:
      The read capacity units consumed by the entire BatchGetItem operation.

      Each element consists of:

      • TableName - The table that consumed the provisioned throughput.

      • CapacityUnits - The total number of capacity units consumed.

    • toBuilder

      public BatchGetItemResponse.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<BatchGetItemResponse.Builder,BatchGetItemResponse>
      Specified by:
      toBuilder in class AwsResponse
      Returns:
      a builder for type T

    • builder

      public static BatchGetItemResponse.Builder builder()

    • serializableBuilderClass

      public static Class<? extends BatchGetItemResponse.Builder> serializableBuilderClass()

    • hashCode

      public final int hashCode()
      Overrides:
      hashCode in class AwsResponse

    • equals

      public final boolean equals(Object obj)
      Overrides:
      equals in class AwsResponse

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      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 an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • toString

      public final String 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.
      Overrides:
      toString in class Object

    • getValueForField

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)
      Description copied from class: SdkResponse
      Used to retrieve the value of a field from any class that extends SdkResponse. 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 SdkResponse.getValueForField(String, Class) method will again be available.
      Overrides:
      getValueForField in class SdkResponse
      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

    • sdkFields

      public final List<SdkField<?>> sdkFields()
      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.
