All Implemented Interfaces:

Persistable

public class AggregationQuery<P extends Persistable,R,T>
extends BaseQuery<R,AggregateTypeQueryOptions<P,R,T>>

As the name suggests, an aggregation query is a special-purposed query for performing an aggregation on your dataset. The same set of query criteria can be applied as the input of the aggregation. Typical use should be to use

Constructor Detail

AggregationQuery

public AggregationQuery()

default constructor useful only for serialization and deserialization

AggregationQuery

public AggregationQuery(CommonQueryOptions commonQueryOptions,
                        AggregateTypeQueryOptions<P,R,T> dataTypeQueryOptions,
                        IndexQueryOptions indexQueryOptions,
                        QueryConstraints queryConstraints)

This constructor should generally not be used directly. Instead use AggregationQueryBuilder to construct this object.

Parameters:

commonQueryOptions - basic query options

dataTypeQueryOptions - query options related to data type

indexQueryOptions - query options related to index

queryConstraints - constraints defining the range of data to query
