Enum Values
SERVER
AggregateSource AggregateSource.SERVER
Perform the aggregation on the server and download the result.
The result received from the server is presented, unaltered, without considering any local state. That is, documents in the local cache are not taken into consideration, neither are local modifications not yet synchronized with the server. Previously-downloaded results, if any, are not used. Every request using this source necessarily involves a round trip to the server.
TheAggregateQuery will fail if the server cannot be reached, such as if the client is offline.
Public methods

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
