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.

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.

getUpToOrBuilder
