getAlias

String getAlias()

 Optional. Optional name of the property to store the result of the
 aggregation.

 If not provided, Datastore will pick a default name following the format
 `property_<incremental_id++>`. For example:

 ```
 AGGREGATE
   COUNT_UP_TO(1) AS count_up_to_1,
   COUNT_UP_TO(2),
   COUNT_UP_TO(3) AS count_up_to_3,
   COUNT(*)
 OVER (
   ...
 );
 ```

 becomes:

 ```
 AGGREGATE
   COUNT_UP_TO(1) AS count_up_to_1,
   COUNT_UP_TO(2) AS property_1,
   COUNT_UP_TO(3) AS count_up_to_3,
   COUNT(*) AS property_2
 OVER (
   ...
 );
 ```

 Requires:

 * Must be unique across all aggregation aliases.
 * Conform to [entity property
 name][google.datastore.v1.Entity.properties] limitations.
 

string alias = 7 [(.google.api.field_behavior) = OPTIONAL];

Returns:

The alias.

getAliasBytes

com.google.protobuf.ByteString getAliasBytes()

 Optional. Optional name of the property to store the result of the
 aggregation.

 If not provided, Datastore will pick a default name following the format
 `property_<incremental_id++>`. For example:

 ```
 AGGREGATE
   COUNT_UP_TO(1) AS count_up_to_1,
   COUNT_UP_TO(2),
   COUNT_UP_TO(3) AS count_up_to_3,
   COUNT(*)
 OVER (
   ...
 );
 ```

 becomes:

 ```
 AGGREGATE
   COUNT_UP_TO(1) AS count_up_to_1,
   COUNT_UP_TO(2) AS property_1,
   COUNT_UP_TO(3) AS count_up_to_3,
   COUNT(*) AS property_2
 OVER (
   ...
 );
 ```

 Requires:

 * Must be unique across all aggregation aliases.
 * Conform to [entity property
 name][google.datastore.v1.Entity.properties] limitations.
 

string alias = 7 [(.google.api.field_behavior) = OPTIONAL];

Returns:

The bytes for alias.

getOperatorCase

AggregationQuery.Aggregation.OperatorCase getOperatorCase()
