org.hibernate.shards.query
Class ShardedQueryImpl

java.lang.Object
  org.hibernate.shards.query.ShardedQueryImpl

All Implemented Interfaces:: org.hibernate.Query, ShardedQuery

public class ShardedQueryImpl
extends Object
implements ShardedQuery
extends Object
implements ShardedQuery

Concrete implementation of ShardedQuery provided by Hibernate Shards. This implementation introduces limits to the HQL language; mostly around limits and aggregation. Its approach is simply to execute the query on each shard and compile the results in a list, or if a unique result is desired, the fist non-null result is returned. The setFoo methods are implemented using a set of classes that implement the QueryEvent interface and are called SetFooEvent. These query events are used to call setFoo with the appropriate arguments on each Query that is executed on a shard.
