com.google.datastore.v1.AggregationQuery.Aggregation.Count
All Implemented Interfaces:
AggregationQuery.Aggregation.CountOrBuilder, com.google.protobuf.Message, com.google.protobuf.MessageLite, com.google.protobuf.MessageLiteOrBuilder, com.google.protobuf.MessageOrBuilder, Serializable
Enclosing class:
AggregationQuery.Aggregation
public static final class AggregationQuery.Aggregation.Count extends com.google.protobuf.GeneratedMessageV3 implements AggregationQuery.Aggregation.CountOrBuilder
 Count of entities that match the query.

 The `COUNT(*)` aggregation function operates on the entire entity
 so it does not require a field reference.
Protobuf type google.datastore.v1.AggregationQuery.Aggregation.Count

    • hasUpTo

      public boolean hasUpTo()
       Optional. Optional constraint on the maximum number of entities to
 count.

 This provides a way to set an upper bound on the number of entities
 to scan, limiting latency, and cost.

 Unspecified is interpreted as no bound.

 If a zero value is provided, a count result of zero should always be
 expected.

 High-Level Example:

 ```
 AGGREGATE COUNT_UP_TO(1000) OVER ( SELECT * FROM k );
 ```

 Requires:

 * Must be non-negative when present.
      .google.protobuf.Int64Value up_to = 1 [(.google.api.field_behavior) = OPTIONAL];
      Specified by:
      hasUpTo in interface AggregationQuery.Aggregation.CountOrBuilder
      Returns:
      Whether the upTo field is set.

    • getUpTo

      public com.google.protobuf.Int64Value getUpTo()
       Optional. Optional constraint on the maximum number of entities to
 count.

 This provides a way to set an upper bound on the number of entities
 to scan, limiting latency, and cost.

 Unspecified is interpreted as no bound.

 If a zero value is provided, a count result of zero should always be
 expected.

 High-Level Example:

 ```
 AGGREGATE COUNT_UP_TO(1000) OVER ( SELECT * FROM k );
 ```

 Requires:

 * Must be non-negative when present.
      .google.protobuf.Int64Value up_to = 1 [(.google.api.field_behavior) = OPTIONAL];
      Specified by:
      getUpTo in interface AggregationQuery.Aggregation.CountOrBuilder
      Returns:
      The upTo.
