Class ItemCollectionMetrics

java.lang.Object
software.amazon.awssdk.services.dynamodb.model.ItemCollectionMetrics
All Implemented Interfaces:
Serializable, SdkPojo, ToCopyableBuilder<ItemCollectionMetrics.Builder,ItemCollectionMetrics>
@Generated("software.amazon.awssdk:codegen") public final class ItemCollectionMetrics extends Object implements SdkPojo, Serializable, ToCopyableBuilder<ItemCollectionMetrics.Builder,ItemCollectionMetrics>

Information about item collections, if any, that were affected by the operation. ItemCollectionMetrics is only returned if the request asked for it. If the table does not have any local secondary indexes, this information is not returned in the response.

  • Method Details

    • hasItemCollectionKey

      public final boolean hasItemCollectionKey()
      For responses, this returns true if the service returned a value for the ItemCollectionKey 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.

    • itemCollectionKey

      public final Map<String,AttributeValue> itemCollectionKey()

      The partition key value of the item collection. This value is the same as the partition key value of the item.

      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 hasItemCollectionKey() method.

      Returns:
      The partition key value of the item collection. This value is the same as the partition key value of the item.

    • hasSizeEstimateRangeGB

      public final boolean hasSizeEstimateRangeGB()
      For responses, this returns true if the service returned a value for the SizeEstimateRangeGB 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.

    • sizeEstimateRangeGB

      public final List<Double> sizeEstimateRangeGB()

      An estimate of item collection size, in gigabytes. This value is a two-element array containing a lower bound and an upper bound for the estimate. The estimate includes the size of all the items in the table, plus the size of all attributes projected into all of the local secondary indexes on that table. Use this estimate to measure whether a local secondary index is approaching its size limit.

      The estimate is subject to change over time; therefore, do not rely on the precision or accuracy of the estimate.

    • toBuilder

      public ItemCollectionMetrics.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<ItemCollectionMetrics.Builder,ItemCollectionMetrics>
      Returns:
      a builder for type T

    • builder

      public static ItemCollectionMetrics.Builder builder()

    • serializableBuilderClass

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

    • hashCode

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

    • equals

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

    • 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)

    • 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.
