      public static QueryEnhancedRequest.Builder builder()
      Creates a newly initialized builder for a request object.

    • toBuilder

      public QueryConditional queryConditional()
      Returns the matching condition of the query.

    • exclusiveStartKey

      public Map<String,AttributeValue> exclusiveStartKey()
      Returns the value of the exclusive start key set on this request object, or null if it doesn't exist.

    • scanIndexForward

      public Boolean scanIndexForward()
      Returns the value of scan index forward, meaning an ascending result sort order, or true if it has not been set.

    • limit

      public Integer limit()
      Returns the value of limit set on this request object, or null if it doesn't exist.

    • consistentRead

      Returns the value of consistent read, or false if it has not been set.

    • filterExpression

      public Expression filterExpression()
      Returns the return result filter Expression set on this request object, or null if it doesn't exist.

    • attributesToProject

      public List<String> attributesToProject()
      Returns the list of projected attributes on this request object, or an null if no projection is specified. Nested attributes are represented using the '.' separator. Example : foo.bar is represented as "foo.bar" which is indistinguishable from a non-nested attribute with the name "foo.bar". Use nestedAttributesToProject() if you have a use-case that requires discrimination between these two cases.

    • nestedAttributesToProject

      public List<NestedAttributeName> nestedAttributesToProject()
      Returns the list of projected attribute names, in the form of NestedAttributeName objects, for this request object, or null if no projection is specified. Refer NestedAttributeName .

      public ReturnConsumedCapacity returnConsumedCapacity()
      Whether to return the capacity consumed by this operation.
      See Also:

    • returnConsumedCapacityAsString

      public String returnConsumedCapacityAsString()
      Whether to return the capacity consumed by this operation.

      Similar to returnConsumedCapacity() but return the value as a string. This is useful in situations where the value is not defined in ReturnConsumedCapacity.
